And when equal amounts of energy were expended (meaning walkers spent more time exercising), one study found runners still lost more weight.Greater weight loss from running than walking during a 6.2-yr prospective follow-up. Williams PT. Medicine and science in sports and exercise, 2013, Nov.;45(4):1530-0315. In this study, not only did the runners begin with lower weights than the walkers; they also had a better chance of maintaining their BMI and waist circumference.
Pedometers also work well for people who simply don't have time or don't take time to walk consistently as a form of exercise. By tracking the number of steps you take each day simply doing your regular daily activities, you may find that you're getting in plenty of exercise. Some experts recommend 10,000 steps a day. Others say this would be an eventual target.
The best way to warm up is to walk slowly. Start off each walk at a leisurely pace to give your muscles time to warm up, and then pick up the speed. Afterwards, gently stretch your leg muscles – particularly your calves and front and back thighs. Stretches should be held for about 20 seconds. If you feel any pain, ease off the stretch. Don’t bounce or jolt, or you could overstretch muscle tissue and cause microscopic tears, which lead to muscle stiffness and tenderness.
Walking helps you get fitter and means your body gets better at using oxygen, so you find it easier to be more active and tire less quickly. Getting active releases feel-good hormones known as endorphins into the bloodstream, and getting that natural high reduces stress and anxiety and ultimately helps to build self-esteem. That’s got to be a good thing!
You can use the cue "warm and slightly out of breath" to gauge your aerobic activity, or you can get more precise and use heart rate. I recommend the heart rate reserve method for calculating a target heart rate. The formula and an example of the method for someone 27 years old, assuming a resting heart rate of 70 beats per minute (bpm), and a training range of 70%, may be found below. Aerobic exercise falls in the range from 40% to 85%. You can plug in your own values to find your aerobic range.

This article provides some general guidelines to help you improve aerobic fitness and gain the many health benefits associated with it. Because everyone has individual health needs and concerns, the fitness suggestions here may not be the best approach for you. The most important thing is to incorporate exercise into your daily routine and to stick with it.
HOW TO START: First of all, start out slow and easy. Just walk out the door. For most people this means head out the door, walk for 10 minutes, and walk back. That's it? Yes, that's it. Do this every day for a week. If this was easy for you, add five minutes to your walks next week (total walking time 25 minutes). Keep adding 5 minutes until you are walking as long as desired. Use one of the plans on the following page as an easy guide.
A loose bottom and loose top is the perfect way to feel comfortable and start the journey of “loving” exercise. I think people get “tired” just from trying to squeeze into spandex. Go straight to the clothes you know are most comfortable—clothes you could fall asleep in. You can weave in some spandex as the weeks go on, but for a beginning fitness walker, keep it comfortable.
The average sedentary adult will reach a level of oxygen consumption close to 35 ml/kg/minute during a maximal treadmill test (where you're asked to walk as hard as you can). Translated, that means the person is consuming 35 milliliters of oxygen for every kilogram of body weight per minute. That'll get you through the day, but elite athletes can reach values as high as 90 ml/kg/minute! How do they do it? They may have good genes for one, but they also train hard. And when they do, their bodies adapt. The good news is that the bodies of mere mortals like the rest of us adapt to training too. Here's how.

Every session of aerobic exercise should include a warm-up and cool-down. The warm-up period should not include static stretching, but should instead be a gradual increase in pace and intensity of the exercise. This allows for the body to increase blood flow to the muscles, and decreases the likelihood of a muscle or joint injury. The warm-up should last between 5 and 10 minutes. The cool-down session should last a similar amount of time as the warm-up, with the pace gradually decreasing. Stretching exercises would be appropriate after aerobic exercise.
Aerobic exercise comprises innumerable forms. In general, it is performed at a moderate level of intensity over a relatively long period of time. For example, running a long distance at a moderate pace is an aerobic exercise, but sprinting is not. Playing singles tennis, with near-continuous motion, is generally considered aerobic activity, while golf or two person team tennis, with brief bursts of activity punctuated by more frequent breaks, may not be predominantly aerobic. Some sports are thus inherently "aerobic", while other aerobic exercises, such as fartlek training or aerobic dance classes, are designed specifically to improve aerobic capacity and fitness. It is most common for aerobic exercises to involve the leg muscles, primarily or exclusively. There are some exceptions. For example, rowing to distances of 2,000 meters or more is an aerobic sport that exercises several major muscle groups, including those of the legs, abdominals, chest, and arms.
Walking doesn't burn calories as quickly as a number of other aerobic exercises, including jogging, swimming or riding a bicycle. Walking, however, is a low-impact exercise that is ideal for a wide range of people, including those who contend with joint pain and aren't physically able to perform more up-tempo exercises. If you choose to use walking as your main source of aerobic exercise, set your weekly schedule to allow for a minimum of 2.5 hours of walking.

You can use the cue "warm and slightly out of breath" to gauge your aerobic activity, or you can get more precise and use heart rate. I recommend the heart rate reserve method for calculating a target heart rate. The formula and an example of the method for someone 27 years old, assuming a resting heart rate of 70 beats per minute (bpm), and a training range of 70%, may be found below. Aerobic exercise falls in the range from 40% to 85%. You can plug in your own values to find your aerobic range.


Here’s what’s happening in your body when you’re running and walking: “Muscle action that propels you from point A to B requires the utilization of a thing called ATP,” explains Janet Hamilton, an exercise physiologist and running coach with RunningStrong. “Your body stores only a limited amount of ATP (enough for only a few seconds of activity), so it needs to replenish that supply, and it does so by metabolizing your stored fuels (glycogen and fat). The process of making useable energy (ATP) from stored fuel (glycogen and fat) is dependent on how much you need and how quickly you need it.” So the more intense the activity, the greater the demand for fuel—and since walking is less intense and demanding than running, it doesn’t demand that ATP be produced at the same rate.
Aerobic fitness can be defined as the ability of the body’s cardiovascular and muscular systems to provide the necessary energy to sustain activity that uses the large muscle groups over an extended period of time. To reach aerobic fitness, a person must engage in continuous activity like jogging, walking, cycling, stair climbing, rowing, or swimming at an intensity level you can maintain for at least 30 minutes, three to seven days per week.

READ: 10,000 Steps Blueprint 11 Steps to a Daily Walking Habit:1. Set a daily target.8,000 to 10,000 steps a day is a decent goal for daily walking. “Walk more” is not specific enough! The power of small wins where you can make a “difficult” but “achievable” goal, such as 10,000 steps a day, means that you constantly challenge yourself.This will help to make walking an ingrained habit. You get positive reinforcement each and every single day when you reach your goal.eval(ez_write_tag([[300,250],'developgoodhabits_com-banner-1','ezslot_3',680,'0']));“Walk more” is not specific enough! 8,000 to 10,000 steps a day is a decent goal for daily walking.2. Make it a 30 Day Habit Challenge (30DHC).One thing I preach about here on the Develop Good Habits (DGH) website is the simple process of the 30 day challenge. If you force yourself to do something each and every day for 30 days, it begins to become an ingrained habit.For 30 days force yourself to walk each and every day. No excuses. You will find that you feel the positive effects and it becomes a habit in this short periods of time.3. Keep a daily log.You can use a notebook, spreadsheet, digital app, website or write it on the wall. How you keep track of your daily walking does not matter.eval(ez_write_tag([[300,250],'developgoodhabits_com-box-4','ezslot_5',149,'0']));All that is important is that you keep track each and every single day. Set daily and weekly goals. Track your results and see how you improve over time.4. Set reminders to walk.Making a goal of 10,000 steps a day does not mean you need to set aside a block of 2 ½ hours for a walk. Set reminders on your one of your electronic devices (computer, cell, etc.) on app like Todoist to buzz you and let you know to take a break and a quick walk.A simple 5 minute walk each hour throughout your working day will put you on the path to reaching the daily walking goal, as well as making you feel better throughout the day (and likely increasing your productivity).5. Buy a Pedometer.It is important to get an idea of how much your walk each and every day. It is also important to all of those logs you will be keeping.There are quite a few pedometers on the market: simple pedometers, pedometers that will do the log-keeping for you, and even ones that make a “game” out of your daily walking. A Pedometer is a simple tool, but an important one.Check out this article on the Best Pedometers, where I discuss 4 different types of pedometers and you can see the best pedometers for Cheapskates, Techies, Multi-taskers and Gamers/Social Addicts.6. Increase incidental walking.Incidental walking is the walking you do each and every day, just to get from Point A to Point B. It is actually quite easy to increase chances of reaching your 10,000 step goal by increasing your incidental walking.Do not search for the closet parking spot, park far away and walk to the stores. If you need to pick something up at the grocery store, don’t drive ¼ of a mile - walk it.7. Make it fun.One of the good things about walking it that it CAN be enjoyable. Bring your iPod. Vary your location. Take a walk on the beach one day, a walk through the city the next and a walk in the forest the day after that.Walking does not need to be a chore. It's a positive lifestyle change that can become quite enjoyable.You can take pictures, meet people and have a good time. Walking does not need to be a chore. Remember it is a positive lifestyle change, and it can become a habit that's quite enjoyable.8. Buy a good pair of sneakers.If you are going to walk a lot, make sure you have comfortable and well cushioned walking shoes. Your legs and feet will thank you, and the lack of pain and discomfort will make the process go smoothly.To find the best pair of sneakers check out the best: Walking Shoes for Men OR Walking Shoes for WomenAdditionally, if your walking takes you off road and is more about hiking than a nice walk through the city, you may want to think about getting footwear for both hiking and walking.The different terrain of hiking rough trails and off-road means your feet have different needs than city walking.Here are two places to help you find the right hiking shoes/boots for your needs. The best hiking boots for women OR hiking boots for men9. Socialize and walk.If you are able to find some friends or family to walk with. This is a good idea for two reasons. The first is that others will help you to stick to your plan. The second is that walking with others can be simply more fun. A nice stroll on with a friend or family member will seem more enjoyable than trying to reach an arbitrary goal.Walk with someone and the walk will be over before you know it. Even if no family and friends are interested, you could join a local “walking club” and find others who will be interested in walking and socializing.10. Drink more water.It is important to drink water before and after your walk (for long walks: during the walk). Staying hydrated helps to keep you feeling great and increases the be positive effects of your walking.Staying hydrated helps to keep you feeling great and increases the be positive effects of your walking.11. Reward yourself.If you have been good about reaching your walking goals, reward yourself. Buy that new dress, go out to the movies or do something to “reward” your efforts. (Sidebar: grabbing a “Big Mac” might be counterproductive here) 155 Ways to Reward Yourself Walk your way to Fitness and Mental HealthMany people have grand ideas of fitness and exercise, only to fall short over a long period of time. Walking has the highest “success ratio” of any new exercise and fitness regime. It is an easy lifestyle change, which brings about huge benefits.When people begin to walk more frequently they often find it a fun and enjoyable part of their routine. They look forward to each and every day, rather than being something they “have to do” to stay fit and healthy.Over time the intensity and duration of the walks can be increased. Remember that for calorie burning purposes, you burn just as many calories walking a mile as you do running it. (The run just gets it done quicker).There are quite a few benefits of walking you will enjoy from making a minimum of walking 10,000 steps part of your regime.It is an essential part of your physical and mental health. Daily walking will make you feel better and become more productive and happy.15 Health Benefits of Walking Every DayWe could all benefit from being a little healthier, but many of us aren’t quite sure where to begin. Fortunately, something as simple as walking every day can greatly improve your health, help you lose weight, and get you feeling more confident about yourself and your body.There are dozens of reasons how walking every day can help you improve your lifestyle, but we’ve compiled this list of the 15 major benefits to every day walking.1. Increase Your LifespanStaying healthy is a crucial part to living a long and happy life, but you don’t need to be running marathons into your seventies to reap the benefits of staying active. A new study has shown that frequent walking can add up to 7.2 years onto the life of an individual.According to the study, the amount of walking the individual does will influence the number of years added to the individual’s life. Even just 75 minutes a week, less than 11 minutes of walking a day, can add almost 2 years onto an individual's life. The American Heart Association recommends that individuals get about 150 minutes of walking a week, which comes to just over 20 minutes a day.For most people, getting 20 minutes of walking is easy. Taking a pet for a walk or just strolling around the block for some relaxation is a great way to get the exercise you need to live longer.2. Manage Your WeightYou don't need to go on extreme diets or exercise rigorously to begin losing weight. Just walking can be enough to see a few pounds drop away. When you walk for extended periods of time, you can actually find that walking helps jump start your weight loss program and may even help you walk off an entire pants size in just a few weeks.If you're looking to use walking to help you lose weight, you may need to engage in a stronger program than just walking from Point A to Point B. Adding interval walking, keeping a certain pace, and walking with exercise bands are all great ways to help promote weight loss as you walk.3. Burns FatWhen we're looking to lose weight or just feel better in our own skin, burning fat is one of the biggest priorities we may have. Many of us who suffer with excess body fat got that way because of a lack of exercise and movement. Luckily, it isn't difficult to begin losing weight, it just takes a few days of brisk walking.Like discussed in point #2, walking is usually used more as a boost to a more intense workout plan. While walking can help you to lose excess fat, you probably aren't going to get the body of your dreams from walking alone. That being said, brisk walking can help you prevent belly fat from growing or from gaining fat.4. Helps Overweight People Get into ShapeSimilar to points #2 and #3, frequent walking is a great exercise for anyone looking to jump start a weight loss plan or workout regimen, particularly those who are currently overweight. Walking is an easy way for individuals who are overweight to get the movement and exercise they need. As walking gets easier, they can begin jogging or running to further promote weight loss and getting in shape.5. Reduces StressWalking can actually reduce stress in a number of ways, including setting your mind into a meditative state, boost endorphins, and give you more energy. The stress-reducing benefits of walking increase even more if you walk outside or bring a friend along.When you walk, you are getting exercise while still taking the time to appreciate your surroundings, which can allow you to forget about your stresses and worries, catch up with a friend in a non-stressful environment, and get the benefits of a good exercise.6. Reduces DementiaThe way that walking helps manage stress is very similar to the way it can help prevent dementia. A recent study showed that just a 20 minute walk a day actually reduced the susceptibility to dementia by 40%. Researchers on the study believe that walking can reduce the risk of dementia by opening up the window of the mind. Walking keeps the brain stress-free, releases endorphins, and allows the blood to flow more freely and fluidly through the brain.The best way walking can reduce the risk of dementia is through preventative measures, but it can also reduce some of the symptoms if patients of dementia begin walking regularly.7. Easy on the JointsWalking has a very low impact on the joints, so it is a great form of exercise for individuals with problems or pain in their joints. Walking is also a great exercise for individuals with joint pain because it is low cost and can be done anywhere, unlike other forms of exercise that may require a certain location, like a pool, or special equipment. Additionally, walking is also one of the top low-impact exercises that can help you lose weight and burn calories.Walking can also be a great way for athletes who have been injured to continue getting exercise they need. As something that is easy on the joints, going for frequent walks can allow them to stay mobile while they are recovering from their injury without needing to worry about compromising their condition.8. Lowers Blood PressureExercise in general can help you to keep your blood pressure at normal, lower rates. Luckily, walking is included in that spectrum and you don't even need to walk for long distance.If you are having trouble finding or making the time to get an adequate exercise in, walking for just three separate times a day can help you keep your blood pressure low.Taking a short, brisk walk in the morning, mid-day, and in the evening can be just as beneficial as getting 30 minutes of intense exercise when it comes to your blood pressure.Walking is an exercise that can help you to keep your blood pressure at normal, lower rates.Having high blood pressure can be extremely damaging to the body and the heart and can lead to serious health conditions like stroke or heart disease.Those who have a family history of such diseases or high blood pressure should seriously consider adding a walking routine into their daily lives and habits.9. Strengthens Your HeartYour heart health is incredibly important to your overall health, which means you need to pay attention to all diseases and illness that can harm your heart.Luckily, frequent walks can keep many of those diseases and conditions at bay, including high blood pressure, high cholesterol, and diabetes. Frequent walking is one of the best things you can do for your heart and preventing heart disease from developing.Getting the recommended 20 minutes a day is a great start for ensuring your heart stays healthy and disease-free.10. Strengthens Your Bones and Reduces Your Risk of OsteoporosisOsteoporosis is a serious condition that causes the bones to weaken and become brittle. While there is no cure for osteoporosis, there are a number of things you can do to strengthen your bones, including walking.Walking is considered a weight-bearing exercise, which means it puts weight on the bones. When doing a weight-bearing exercise, you're fighting against gravity to put pressure on the bones, which forces the bones to work more and gain strength.Staying still can be very harmful if you have osteoporosis, but it can also be difficult to find exercises that are not too risky for the condition. This makes walking one of the best exercises for individuals with osteoporosis.As we already mentioned, walking is easy on the joints, so while individuals with osteoporosis do not need to worry about further damaging their bones, they can still burn calories and get the exercise everyone needs.11. Reduces Depression and Improves Your MoodAs we already pointed out, walking can reduce your stress level. Having a high level of stress can cause you to be irritable and may even result in mental conditions like depression.In a recent study, researchers looked at how walking effected those suffering from depression. By having some of the group walk for 25 minutes in different areas of a city, they examined how walking in certain environments influenced the individual's moods.According to the study, those who spent their time walking in green areas had better moods and felt more engaged when they left their walking environment.Whether you're suffering from depression or just need to clear your head, taking about a half hour walk through a park can get you feeling better.This suggests that frequent walking in green, natural areas can reduce feelings of depression and make you feel happier.Whether you're suffering from depression or just need to clear your head, taking about a half hour walk through a park can get you feeling better.12. Boosts Your MemoryWhen we are physically fit and take the time to take care of our bodies, we usually experience higher levels of cognitive function. This means we can think more clearly, have an easier time remembering things, and are less likely to experience things like dementia when we grow older.In a recent study that looked at women, their physical activity, and their level of cognitive decline as they aged, it found that the more physical an individual is, the less likely they are to experience high levels of mental decline.By completing the 20 minutes of walking suggested each day, we can improve our memory and ward off cognitive diseases that can drastically decrease our quality of living.13. Improves Your SleepThere are a number of ways that walking can help you to improve your sleep. Exercise in general helps our body deal with stress, work off excess energy, and better prepare for sleep.As we've addressed in previous points, walking is a great way to deal with our stresses and help to manage our moods, which can frequently result in us staying up all night worrying about things like relationships, work, or finances.Frequent walking can help individuals who have trouble sleeping both by helping them fall asleep faster and stay asleep longer.In a study with chronic insomnia sufferers, which includes individuals who cannot fall asleep easily as well as individuals who have trouble staying asleep through the night, they found that a moderate-intensity exercise helped reduce the symptoms associated with chronic insomnia. That same study found that other forms of exercise, like running or lifting weights, did not help individuals sleep.This allows us to believe that even if you are an avid runner or weight lifter, you should still consider adding walking into your routine, especially if you find yourself having trouble staying asleep or falling asleep.14. Tones Up Your Legs, Butt, and StomachWe already addressed the many ways that walking can help you to lose weight and drop fat, but did you know it can also help you tone up? When you switch up your walking routine by adding new elements and locations, you can start to see the benefits you may have only believed came with intense workout plans.There are number of things you can do to tone your legs, butt, and stomach as you walk. One of the biggest suggestions is walking up hill, which can engage many muscles in your body and allow you to see results.If you don't have hills to walk up, find a place that requires you to walk up stairs, which can provide a similar effect. Other ways to increase your muscle movement and engagement when walking is to tighten your muscles as you walk. This gives them a similar experience to being naturally engaged, only they are experiencing manual engagement, causing them to work hard.Additional ways to tone up from walking include picking up your speed. If you're looking to get more benefit from your walking, consider walking faster or for longer periods of time. It is recommended to walk somewhere that you enjoy the scenery, which can increase the amount of time you're willing to walk.15. Boosts Your Vitamin DVitamin D is crucial to our health and happiness, and the best way to get enough of the necessary vitamin is through spending time in the sun.Being deficient in Vitamin D can lead to an increase of developing cardiovascular disease, and cause asthma in children, and may even cause cancer. It is also known to cause things like bone pain and muscle weakness.Taking frequent walks outside, particularly in the middle of the day when the sun is at its brightest, can boost your levels of Vitamin D and get you feeling better. Mid-day walking is also crucial in the winter, when the days are shorter and it can be harder for individuals to get the amount of time in the sun that they need.Did you enjoy this list?eval(ez_write_tag([[336,280],'developgoodhabits_com-large-leaderboard-2','ezslot_7',150,'0']));We hope that you found some useful information!If you're looking to get a little healthier, don't let yourself believe it is too difficult. Adopting just 20 minutes a day of brisk walking can give you all the above benefits and get you feeling better, more confident, and happier.Walking is a great exercise when used alone, but when used in conjunction with more rigorous exercises and physical exertions, adding walking to your routine can give you the health you've always dreamed of.​Also, if you'd like additional tools ​to lose weight and maximize your exercise, then check out these 11 apps that will help you plan out healthy meals.
Keep in mind that both fuels are almost always burned simultaneously, except during the most intense, short-term bursts of energy, like sprinting and weightlifting. It's the percentage of fat and carbohydrate burned that changes during a workout depending on the intensity, but you almost never burn just one exclusively. You burn fat while you're at rest, and you burn it during virtually every moment of exercise. It's a myth to think that it takes 20-30 minutes of exercise before your muscles start burning fat.

There’s no need to try to squeeze in all of your steps in one shot. In fact, you may get more benefit if you spread them out throughout the day. If you often get stuck at your desk for hours on end during your workday, try setting a reminder for every hour, and spend 15 minutes walking. If you’re able to repeat this five times a day, you may reach your 10,000 step goal before you leave work!


Whatever makes you feel comfortable is the easy answer. There is no need for fancy spandex or workout clothes, unless that’s what you like. As you start moving farther and faster, you may want to get dedicated fitness walking clothes that wick away sweat or allow you to layer for different weather conditions, but for a beginning fitness walker, comfort trumps everything else.
There you have it. Aerobic exercise is awesome stuff! It strengthens your heart, adds strength to your muscles and makes them more efficient fuel-burners, increases your endurance and your energy, improves your mood, makes you fit and healthy, and much, much more. It could take as little as 30 minutes out of your day for a tremendous payoff so I suggest giving it a shot. Follow my advice for getting started by doing only what is realistic and build up slowly. You have only health and fitness to gain, and you're worth it! Good luck!
Exercise is good for the brain but walking in specific is good for boosting your memory. A 2011 study published in The Proceedings of the National Academy of Sciences showed how walking for 40 minutes at a stretch three times a week could increase the volume of the hippocampus by 2%, which is fairly significant. Another study that was presented at the 2014 annual meeting of the American Association for the Advancement of Science, regular brisk walks can slow down the shrinking of the brain and the faltering mental skills that old age often bring. The study was done with men and women between the ages of 60 and 80 and it concluded that taking a short walk three times a week increased the size of that part of the brain linked to planning and memory.
Greater stroke volume means the heart doesn't have to pump as fast to meet the demands of exercise. Fewer beats and more stroke volume mean greater efficiency. Think about a pump emptying water out of a flooded basement. The pump works better and lasts longer if it can pump larger volumes of water with each cycle than if it has to pump faster and strain to get rid of the water. High stroke volume is why athletes' hearts don't pump as fast during exercise and why they have such low resting heart rates; sometimes as low as 40 beats per minute, whereas the average is 60-80 beats per minutes.

Osteoporosis is a disease characterized by low bone density, which can lead to an increased risk of fracture. The good news is that exercise may increase bone density or at least slow the rate of decrease in both men and women. It may not work for everyone, and the precise amount and type of exercise necessary to accrue benefits is unknown, but there is evidence that it can help. In children there is good news, too. It seems that active children have greater bone density than sedentary children and that this may help prevent fractures later in life.

A 2014 study published in the Journal of the American Medical Association showed how walking from an early age can help you stay mobile and independent during old age. The sample size included people between the ages of 70 and 89. After 2.5 years, researchers found that the group of adults which exercised regularly were 28% less likely to become disabled and also 18% less likely to have any episode of physical disability.
It makes the world feel more fundamentally right. I think it’s because our species is supposed to walk. We are built to walk. We are not built to sit, or crouch, over computers or phones. We are not built to slump on sofas, binge-watching box sets. We are built to stand up, swing our legs, plant our feet, and just go. Of course doing one of the things our bodies are primarily designed to do, would make our heads feel really and truly good.
Your body’s immune system should function properly at all times to prevent infections, diseases, and death. Walking is a great way to boost your immunity. Walking at least 30 minutes a day can help bolster the activities of the immune cells, namely, the B-cells, T-cells, and the natural killer cells (13). It helps release the WBCs at a faster rate, thereby allowing your body to heal quickly (14). 

Walking is one of the simplest ways to get fit and maintain heart health. The American Heart Association's guidelines for physical activity indicate that healthy adults should aim to walk a minimum of 150 minutes per week, or 30 minutes every weekday. Walking seven days per week will burn more calories, and you can add challenges to your walking workout that make it more of a cardiovascular or strengthening exercise.
The biggest variable in burning calories walking is how far you walk and how much you weigh. Going faster will allow you to go farther and therefore burn more calories in a set period of time. But you will burn approximately the same calories per mile over a wide range of walking speed. Running can burn more calories per mile as it includes lifting the body off the ground.
"By adding some variables into the mix you can turn a simple walk into a fun, fast interval session, burning a high level of calories, and in turn, crushing your fat cells,” adds Rob McGillivray, Founder of RETROFIT in West Hollywood. “Essentially we burn the most calories by repeatedly raising and lowering the heart rate, as opposed to keeping the heart rate at one steady pace, whether that be high or low. So, if you were to compare the heart rate fluctuations of someone walking up a mixture of steep hills and then add in variations of walking speeds, styles of walking (such as lunging, striding, side cross overs, etc.) to that of someone primarily running at a medium pace on a level gradient, you could see greater all round results on both your body's caloric burn and a greater degree of lower limb muscle groups being targeted. It is also said that hill walking, as opposed to running on a level gradient, can enable you to burn more fat without attacking lean muscle tissue.”
Add a simple four-minute stretch routine a few days a week after your walk to maintain your natural range of motion. Just stand up, even if you're at work fully dressed in work clothes. Put one leg back, bend the front knee, and lean forward to stretch the calf muscle. For thighs, grab your ankle from behind, keep your knees close together. Lean forward to stretch your lower back.

‘Aerobic’ exercise refers to exercise that requires the consumption of substantially more oxygen than at rest. It is of a light to moderate intensity, and can be undertaken for a prolonged duration (many minutes to several hours) without excessive fatigue. Examples of aerobic exercise include walking, jogging, swimming or cycling at a steady pace. Another example would be dancing or ‘aerobics’ classes.Regular exercise causes your body to make adjustments that result in improved health and physical functioning. Continuing with regular exercise enables your body to maintain these benefits. Regularly doing the right types of exercise at the correct intensity, and for an appropriate duration, results in the most benefit.The benefits of aerobic exercise can be broadly categorised as either ‘fitness’ (physical capacity) or ‘health’. Fitness and health are linked, and most forms of aerobic exercise will help you achieve both.Fitness — including increased cardiorespiratory fitness and endurance (stamina)Regular aerobic exercise improves your cardiovascular fitness by increasing your capacity to use oxygen. It does this by increasing your heart’s capacity to send blood (and hence oxygen) to the muscles. This is mainly achieved through an increase in the size of the heart’s pumping chambers (ventricles), which means that your heart doesn’t have to beat as fast to deliver the same amount of blood. This is evident in a slower resting heart rate, and a slower heart rate for the same exercise intensity.As you get ‘fitter’, particular activities (such as walking or jogging at a specified speed) will become easier.You’ll also be able to undertake the activity for longer (known as endurance), and/or at a higher intensity (e.g. jogging at a faster speed). The same applies to activities such as cycling or swimming, but it should be noted that fitness tends to be specific. So jogging will provide only limited benefits to your swimming fitness and vice versa. However, a side-benefit you may notice is that you also have increased stamina for the everyday activities of life, not just for exercise.Other fitness improvements occur in the exercising muscles, and are specific to those muscles being used in the mode of exercise (e.g. walking, running, cycling, or swimming). These include an increased capacity for the muscles to take up and use the additional oxygen being delivered by the heart.Reduced risk of certain health problemsRegular aerobic exercise has been shown to reduce the risk of heart disease, high blood pressure, type 2 diabetes, colon cancer and breast cancer. It can lower blood pressure and improve your blood cholesterol by reducing the levels of LDL-cholesterol (so-called ‘bad’ cholesterol) and increasing the amount of HDL-cholesterol (so-called ‘good’ cholesterol). It can also reduce anxiety, stress and depression, as well as instilling a general sense of well-being. Regular aerobic exercise has even been shown to have the potential to increase your lifespan.Low-impact aerobic exercise such as swimming is valuable for improving general health and fitness in people who have arthritis or other conditions that limit their ability to do weight-bearing exercise.Importantly, whereas fitness tends to be quite specific, many health benefits can be gained from any form of aerobic exercise. Additionally, the health gains can be achieved from relatively moderate amounts of exercise — moving from a lifestyle involving no exercise to one that involves some exercise can lead to substantial improvements in health.Weight controlAerobic exercise burns up energy (calories). Regular sessions of 30 to 60 minutes of low to moderate intensity aerobic exercise (at around 55 to 70 per cent of maximum heart rate) can be an important part of a weight loss or weight management programme that is also mindful of the energy (calories) consumed as food.However, many of the health benefits associated with aerobic exercise occur independently of weight loss. Evidence from large studies has shown that active, overweight people do not have a greater risk of many diseases than inactive people who are not overweight. From a health perspective, it is of course best to be both active and a healthy weight, but if weight reduction is a problem, it doesn’t mean that the exercise is having no benefit.Improved bone and muscle healthYour risk of osteoporosis (excessive bone thinning as you age) can be reduced by regular weight-bearing aerobic exercise such as brisk walking.By stimulating the growth of tiny blood vessels in your muscle tissues, aerobic exercise has also been shown to lessen the pain experienced by people who have fibromyalgia or chronic low back pain, as the oxygen supply to the muscles is improved and waste products are removed more efficiently.Social benefitsRegular aerobic exercise can have social benefits too, whether you walk with a friend, play tennis with workmates, or form a social cycling team. Exercising with friends can also be the most effective way of ensuring that you do it regularly.Aerobic exercise precautionsAs with any form of exercise, be aware of over-exercising, either by doing aerobic exercise too hard, for too long or too often. This approach can lead to injury, and abandoning of your fitness programme. Remember to build up gradually from your current activity level, and not to progress too rapidly. If you are new to regular aerobic exercise, several weeks of low to moderate intensity aerobic exercise are usually advised before introducing more vigorous aerobic exercise sessions.If you have existing health problems, are at high risk of cardiovascular disease, or have muscle, bone or joint injuries, check with your doctor before undertaking an aerobic exercise programme. Also, men aged over 40 years and women aged over 50 years who have not exercised regularly in the recent past should check with a doctor before undertaking a programme of vigorous physical activity.

There’s no need to try to squeeze in all of your steps in one shot. In fact, you may get more benefit if you spread them out throughout the day. If you often get stuck at your desk for hours on end during your workday, try setting a reminder for every hour, and spend 15 minutes walking. If you’re able to repeat this five times a day, you may reach your 10,000 step goal before you leave work!

Classes are great for people who like to exercise with others, who like to dance, who like music and rhythm, who want the extra motivation and energy that an instructor and class provides, and who prefer the structure and schedule of a regular class. Classes, equipment, and videos are all great ways to stay fit and healthy, but if you're limited by injury or other conditions, then aerobic exercise chair workouts may be just the thing (see resources for online vendors). The instructor leads you through a workout in a chair and it's great exercise. You might not need chair exercise, but you may have a parent or friend who does. Exercise videos and DVDs make great gifts!
1. Walk as much as you can. The University of Warwick study compared people with at least one sign of metabolic syndrome—a group of risk factors (high blood pressure, fat around the waist, high blood sugar, and high triglycerides and cholesterol) for heart disease—to those with no risk factors. They found that those who got the least activity had the most risk factors, and those who walked the most—accumulating at least 15,000 steps per day—had healthy BMIs, smaller waists, lower cholesterol and blood pressure, and better blood sugar control.
It is appropriate to do aerobic exercise every day. There is no need to rest in between sessions unless you are at an extreme level of training, such as preparing for a marathon, or if you experience reoccurring joint pain. If joint pain is a limiting factor, it would be appropriate to alternate less painful exercises with those that may cause joint pain or to discontinue the painful exercise altogether.
The second recommendation is from the American College of Sports Medicine. The ACSM recommends 20-60 minutes of continuous aerobic activity (biking, walking, jogging, dancing, swimming, etc.) three to five times a week, at 60%-90% of maximum heart rate, and two to three days of resistance training. This is a more formal, "workout" recommendation, although you can also accumulate the more intense workout in bouts of 10-15 minutes throughout the day if you like. Follow this recommendation and your fitness and your health will improve.
