To achieve a training response, athletes should exercise 3 to 5 times per week for at least 20 to 60 minutes. Fitness level can be improved with as little as 10 minutes of exercise if done 2 to 3 times per day. If the goal is also to lose body fat, athletes should exercise for at least 30 to 60 minutes. Athletes who are not fit will need to start with lesser amounts of exercise. They can slowly add more time as their endurance improves. Increasing the level of exercise at about 10% per week is a good goal to prevent overuse injury.
Aerobic exercise involves regular body part (e.g., arms or legs) movements that increase workload on the cardiovascular system. It is convenient and useful to think of the intensity of aerobic exercises in metabolic equivalents, or METs. One MET represents the amount of energy used at rest, and two METs is twice that much energy expenditure per unit of time, and so on. Aerobic exercise is widely recommended in contemporary guidelines. However, guidelines also indicate that exercise regimens are contraindicated in patients with unstable cardiovascular conditions, including but not limited to uncontrolled severe hypertension (BP ≥ 180/110 mm Hg). Conditions under which stress testing should be performed before initiation of an exercise regimen have been described.37 

Imagine that you're exercising. You're working up a sweat, you're breathing hard, your heart is thumping, blood is coursing through your vessels to deliver oxygen to the muscles to keep you moving, and you sustain the activity for more than just a few minutes. That's aerobic exercise (also known as "cardio" in gym lingo), which is any activity that you can sustain for more than just a few minutes while your heart, lungs, and muscles work overtime. In this article, I'll discuss the mechanisms of aerobic exercise: oxygen transport and consumption, the role of the heart and the muscles, the proven benefits of aerobic exercise, how much you need to do to reap the benefits, and more.
A recent randomized crossover trial of lower-intensity or high-intensity exercise showed decreases in clinical SBP with both types of exercise. However, there was no decrease in mean day or nighttime ambulatory BP with either form of exercise.42 Aerobic interval training (AIT) combines episodes of high-intensity with episodes of low-intensity aerobic exercise. At least two randomized studies have suggested an advantage of AIT over continuous aerobic exercise.43,44 Some patients, of course, have limited ability to use their legs, and upper extremity aerobic exercise also has been shown to lower BP.45
No matter how fast you walk, though, make sure you’re moving at a pace that will challenge your heart and improve your health. You should be able to hold a conversation, but not be moving so leisurely that you could sing a song. If you feel your body begin to get warm and sense that your heart rate is slightly elevated those are other signs you’re moving at an appropriate pace. (Looking for a challenge? This simple, surprising move will make your walking routine way more effective.)

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.
Regardless of how many calories you burn, adding walking into your daily routine can have profound health benefits! Going on regular, brisk walks can help you maintain a healthy body weight and stave off diseases like diabetes, heart disease, high cholesterol and hypertension. In addition, regular walking helps improve bone density and leads to increased muscle strength.
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!

The research, presented at the European Society of Cardiology (ESC) Congress, followed 69 people between the ages of 30 and 60. Those who engaged in daily moderate exercise, such as a brisk walk or jog, high-intensity interval training (HIIT), and strength training experienced anti-aging benefits that could add an additional three to seven years to your life.1 

No study has been more conclusive about the role of lifestyle changes (diet and exercise) in preventing diabetes than the Diabetes Prevention Program. It was a study of more than 3,000 individuals at high risk for diabetes who lost 12-15 pounds and walked 150 minutes per week (five 30-minute walks per day) for three years. They reduced their risk of diabetes by 58%. That's significant considering there are 1 million new cases of diabetes diagnosed each year. Aerobic exercise can also improve insulin resistance. Insulin resistance is a condition in which the body doesn't use insulin properly, and this condition can occur in individuals who do and do not have diabetes. Insulin is a hormone that helps the cells in the body convert glucose (sugar) to energy. Many studies have shown the positive effects of exercise on insulin resistance. In one, 28 obese postmenopausal women with type 2 diabetes did aerobic exercise for 16 weeks, three times per week, for 45-60 minutes, and their insulin sensitivity improved by 20%.
Raise your hand if you’re stressed out. OK, OK, put both your hands back down. Most of us swim in a pool of stress every day and that takes a serious toll on our mental and physical health.  But science says one of the benefits of walking is it’s one of the fastest, most effective ways to calm down. Moving clears cortisol, the “stress hormone”, out of your system and also helps stop the never-ending stream of worries going through your mind, according to a study published in The American Journal of Cardiology. Here are tricks for getting the most happiness out of your walk.
Regular cardio (at any speed) is part of a healthy lifestyle. But, lap for lap, running burns about 2.5 times more calories than walking. Running may also help control appetite, so runners may lose more weight than walkers no matter how far the walkers go. Still, running isn't for everyone, and going full-speed might increase injury risk. Adding weights or an incline can help pick up the intensity while maintaining a slower pace.
Select an activity with a high probability that you will stick with it. It doesn't necessarily have to be fun, it just has to be something realistic that you are willing and able to do. You're probably setting yourself up to fail if you work 12 hours a day, take care of three young children, and still plan to use a treadmill at a gym that's a 45-minute commute from where you work or live. Instead, choose something more convenient. I love the "five minutes out, five minutes back" plan to get started. Just like it sounds, you walk out for five minutes at a moderate intensity (aerobic exercise), turn around, and walk back. That's it. Ten minutes of walking and off you go about your day. If you feel ambitious, start with seven and a half or even 10 minutes out and back, and add some abdominal crunches if you like when you finish. Keep in mind that you can always add more later on. The important thing is to get started.
In normal daily activity, adults cover about 2-3 miles. About 2,000 steps equal a mile. To make walking a beneficial activity, you would need to come up with at least another 4,000 steps in a day. You can find ways to add steps here and there, such as walking farther from parking lots, taking stairs when available instead of escalators and elevators, walking the long way to get somewhere in your office building, walking your children to school, having a walk/talk meeting instead of sitting down in a conference room, or planning a short walk around the block as a break.
The statistics are impressive: The American Diabetes Association says walking lowers your blood sugar levels and your overall risk for diabetes. Researchers at the University of Boulder Colorado and the University of Tennessee found that regular walking lowered blood pressure by as much as 11 points and may reduce the risk of stroke by 20% to 40%. One of the most cited studies on walking and health, published in the New England Journal of Medicine in 2002, found that those who walked enough to meet physical activity guidelines (30 or more minutes of moderate activity on 5 or more days per week) had a 30% lower risk of cardiovascular disease, compared with those who did not walk regularly. "The physical benefits of walking are well documented," says Scott Danberg, director of fitness at Pritikin Longevity Center + Spa in Miami. With impressive results like these, there's a good chance you'll get a pat on the back from your doc at your next checkup.
‘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.

Bone density may not be one of the most exciting health benefits of walking, but it’s an important one. People with stronger bones avoid osteoporosis and all the problems that come with it like fractures, disability, and spine shrinkage (seriously, you can get shorter). And the best way to get strong, healthy bones is by doing weight-bearing exercises like running, dancing and, yes, walking, according to a large study done by Oxford. But when it comes to bones, it’s definitely use it or lose it: To keep your bones strong you have to keep exercising. The researchers found that adults who walked regularly had better bone density throughout their lives than their inactive friends. Find out which common walking mistake causes 11,000 injuries every year.
Nina Barough is well known to power walkers in the UK. She founded the Walk the Walk Charity in 1999, and organises events, including The Moonwalk, a unique power walking marathon. The annual walk, which starts and ends in Battersea Park, London, attracted 15,000 walkers in 2003 and is in the process branching out worldwide. Nina lives in Finchampstead, Berkshire.

Still, running isn't for everyone, and going full-speed might increase injury risk. Adding weights or an incline can help pick up the intensity while maintaining a slower pace.
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.
1. It counteracts the effects of weight-promoting genes. Harvard researchers looked at 32 obesity-promoting genes in over 12,000 people to determine how much these genes actually contribute to body weight. They then discovered that, among the study participants who walked briskly for about an hour a day, the effects of those genes were cut in half.
Increase your time. With each walk, increase your walking time by 30 seconds to 1 minute until you are able to sustain a 10-minute walk. Again, do not fret if you can't go longer than the day before. Set the goal and keep at it and you will reach it faster than you think. After reaching 10 minutes, your rate of increasing may slow, but continue trying to increase your walking time by 5 minutes each week.

The effect of this is even more striking than that of the active foot: the abdominal muscles seem to kick in on their own, and the collar bones drop and straighten in a queenly, warrior fashion. My walk becomes a lot more regal, yet paradoxically, faster. “May I touch you?” Hall asks again, because I can only keep this up for maybe 20 paces before I forget and sink back into my hips.
The good news is that you don’t need to walk at a vigorous intensity for health or aerobic fitness benefits. Walking at a moderate intensity will increase your aerobic fitness and, more importantly, your endurance (the ability to carry out activities for longer with less fatigue). This is because it allows your body to burn fat more efficiently, improves delivery and use of oxygen in the muscles, and improves mitochondria density and efficiency (these are producers of energy in our body), all leading to greater capacity to undertake tasks with less fatigue.
I recommend using a pedometer, or better yet, one of the newer wearable fitness trackers, to keep track and find out how far you normally walk. At first, you may be surprised to realize just how little you move each day. Tracking your steps can also show you how simple and seemingly minor changes to the way you move around during the day can add up. Plus, it’s motivating to see your steps increase throughout the day, which makes it easier to push yourself a little farther to reach your 10,000-step goal.
These changes yield major heart health benefits, with research published in the American Journal of Cardiology showing that aerobic training is the most efficient method of exercise for improving cardiovascular health.

Your weight x distance = energy used walking. Time does not matter as much as distance. If you speed up to walking a mile in 13 minutes or less, you will be burning more calories per mile. But for most beginning walkers, it is best to increase the distance before working on speed. A simple rule of thumb is 100 calories per mile for a 180 pound person.


The hamstring, by the way, has two functions, hip extension and knee flexion. One it really enjoys – knee flexion – and the other, not so much. If you stand on one leg and swing the other backwards and forwards, you can see this immediately: your forward swing will be higher than your backward, and on the backswing you’ll want to bend your knee. But when the hamstring is properly “recruited” – this is what it’s called, when a movement activates a muscle – it has huge propulsive power, as well as opening up the world in which your glutes (butt muscles) can also do some of the work.

"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.”
Active women are less likely to get breast cancer.There are reports showing that other cancers are reduced with moderate physical activity as well. Esophageal cancer, liver cancer and others are reported to be reduced by exercise.Exercise lowers that level of some hormones like estrogen, insulin and certain growth factors that increase cancer risk.
Add Weights: Another way to add intensity to a walking routine is to use weights. “Whether you're on the treadmill or you hop off on your ‘rest interval,’ you can add weight to keep your heart rate up and add some strength training into the mix,” says Crockett. “While you're walking on an incline, adding some dumbbell shoulder presses or dumbbell jabs can help you tone your arms and burn even more calories. [Or] hop off the treadmill after your fast interval and try some quick high repetition exercises, such as dumbbell squats, squat to press, weighted jumping jacks or weighted sit ups.”
There is also an ever increasing array of affordable home fitness products available, such as steps, skipping ropes (remember to put your breakables a safe distance away), rebounders (rebounding is considered by NASA to be the “most efficient and effective exercise yet devised by man”), dance mats that you can use with your games console and exercise videos so that you can workout with your favourite celebrity.

You need hand-eye coordination to punch a pad or punching bag so it may be trickier than you think — but you’ll soon improve with regular practice. You won’t get a black eye because there’s no combat involved, but there’s a risk of injury to hands and wrists if you’re punching a pad or punching bag. Many gyms provide boxing mitts, however you’ll need to bring your own cotton gloves to wear inside.
Use the 1-to-10 scale of perceived rate of exertion to measure endurance. Think of 1 as watching TV; 10 is gasping for air (you can't go any further). Daily walks, for example, are 5 or even 6-6.5 sometimes. Twice a week, crank it up to 7, 8, or 9 on a steep hill for a few minutes. Now you're burning serious calories and building real aerobic fitness through interval training.
Metabolic syndrome—the evil trifecta of increased blood pressure/cholesterol, high blood sugar, and fat around your waist—is one of the worst side effects of our sedentary lifestyle. It signals diabetes, heart disease, and even early death. But we have an old-fashioned cure to this modern-day disease: exercise. Any cardio exercise, including walking, can stop metabolic syndrome and even reverse the damage, according to a study published in Circulation. But intensity is the key to revving up your metabolism. Rather than just taking a leisurely stroll, try alternating walking fast and slow.  Here 16 more ways to channel the benefits of walking into weight-loss.

Your heart gets stronger and pumps more blood with each beat (larger stroke volume). Elite athletes, as I just mentioned, can have stroke volumes more than twice as high as average individuals. But it's not just that. Conditioned hearts also have greater diameter and mass (the heart's a muscle too and gets bigger when you train it), and they pump efficiently enough to allow for greater filling time, which is a good thing because it means that more blood fills the chambers of the heart before they pump so that more blood gets pumped with each beat.


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.

In the end, vigorous running wins out for calorie burn, but remember that calories aren't everything. Obsessing over exactly how many calories you consume or burn is just as unhealthy as not exercising at all. So choose the activity you love most—whether it be walking or running—and focus less on the calories and more on how much better you feel after doing it.
My suggestion for getting started is almost always the same. Keep it simple, keep it practical, keep it convenient, keep it realistic, keep it specific, and don't try to make up for years of inactivity all at once. Select any activity and amount of time where the probability of sticking with it is high. You may not love walking, but if you can do it right outside your door, and it requires no special equipment, and you already know how to do it (you've been walking your entire life!), then walking might be your best bet for getting started because it's so convenient.
No more tedious calculations after returning from the gym - this walking calorie calculator will calculate the calories burned walking or running on a treadmill. All that it needs are some basic information about your walking or running exercise, such as the distance and average speed, and it will provide you with the most accurate measure of how many calories does walking burn.
Also known as a cooling vest or ice vest, the revolutionary vests must be used appropriately for you to experience the best results. You need to use it only when you are at a comfortable temperature. Examples of these scenarios are sitting in your car, watching a football game, driving, working in the office or resting in a room or in an outdoor area when not exercising.
Physical therapist, Col. Pauline Potts and Dr. Kenneth Cooper, both of the United States Air Force, advocated the concept of aerobic exercise. In the 1960s, Cooper started research into preventive medicine. He conducted the first extensive research on aerobic exercise on over 5,000 U.S. Air Force personnel[13][14] after becoming intrigued by the belief that exercise can preserve one's health. Cooper published his ideas in a 1968 book titled, "Aerobics". In 1970, he created his own institute (the Cooper Institute) for non-profit research and education devoted to preventive medicine and published a mass-market version of his book "The New Aerobics" in 1979. Cooper encouraged millions into becoming active and is now known as the "father of aerobics".[15][16] Aerobics developed as an exercise form in the 1970s and became popular worldwide in the 1980s after the release of Jane Fonda's exercise videos in 1982.[17][18]

Despite the weakness, fatigue, loss of joint range of motion, and orthopedic changes, maintaining aerobic activity must be part of a comprehensive rehabilitation program. Studies have shown that aerobic capacity can be increased, improving functional abilities (Wright et al., 1996; Taivassalo et al., 1999). Continuous low to moderate resistive and aerobic exercises to promote fitness are suggested (Ansved, 2003). However, few if any studies have evaluated the long-term benefit or risks. Cardiac disease is one of the most common causes of death in patients with DMD. Potentially, cardiomyopathies and conduction abnormalities pose serious risks for patients with MD during aerobic and/or resistance training. The American Academy of Pediatrics (2005) recommended that, after the confirmation of DMD or Becker muscular dystrophy (BMD), a referral for cardiac evaluation with a specialist be made. The cardiac evaluation should include a complete history and physical, ECG, and transthoracic echocardiography (TTE). A complete cardiac evaluation should be completed every other year. In addition, starting at the age of 10 years or after the onset of cardiac signs/symptoms, cardiac evaluations should be completed annually. Specifically, symptoms of dilated cardiomyopathy, heart failure, cardiac arrhythmias, and respiratory abnormalities should be identified and treated.
The research, presented at the European Society of Cardiology (ESC) Congress, followed 69 people between the ages of 30 and 60. Those who engaged in daily moderate exercise, such as a brisk walk or jog, high-intensity interval training (HIIT), and strength training experienced anti-aging benefits that could add an additional three to seven years to your life.1
Whether you’re just having a down day or a down life, taking a walk can instantly lift your mood—especially when you go outdoors. Not only can walking make you less depressed, but according to a study published in the Archives of Internal Medicine, depression sufferers who took a daily walk showed just as much improvement in their symptoms as people on medication. In fact, 60 to 70 percent of the subjects could no longer even be classified as depressed. And a follow-up study foun5d that the mood boost from the walk lasted longer than that of the medication. Find out exactly how long you should walk if you want a mood boost.
“With that being said, walking is a really good form of exercise and can help you reach your fitness and weight-loss goals. As a lifelong track athlete, who has marveled at race walkers (check out the Olympic walkers on YouTube!), I don’t scoff at walking,” says Ford. “In fact, walking is the suggested workout over running for many people. For example, those with knee, ankle and back problems and also for people who are overweight to obese. Walking is a lower impact exercise and can be done for longer periods of time.”
The thinking has also changed somewhat on whether there’s a threshold minimum workout duration required to reap cardiovascular health benefits from aerobic activity. HHS’s new physical activity guidelines eliminated the long-standing recommendation that exercise had to last at least 10 minutes to count toward your daily total. (4) The new guidelines emphasize that small bouts of activity throughout the day can add up to big health benefits.
Vary your walking workout to keep it interesting and you will also burn more calories. Incorporate a couple of inclines into your walking route. If you exercise on a treadmill, set it at a slope for part of the time. Walking more extreme inclines makes your workout more like hiking, which burns twice the amount of calories than walking on a flat route.
So to recap, walking daily is excellent. Walking daily for 10,000 steps or more is even better. And if you can do so outdoors in the sunshine, and barefoot for grounding, you’ll enjoy even greater benefits. To be clear, you don’t have to do your 10,000 steps a day all at once. You can break up your daily steps into any size increments that work for you. You might walk for one hour in the early morning, 30 minutes during your lunch hour, and another hour in the evening. Or you might enjoy taking shorter 20-minute walks throughout your day.
Recent research showed that wearing a fitness-tracking wristband (the FitBit One) did help overweight postmenopausal women increase their activity levels by nearly 40 minutes (and 789 steps) a week.2 Wearing a pedometer did not have such an effect. However, if you're committed to making your 10,000 steps a day, does that mean you're on your way to becoming physically fit?
