The more I walked, the more thoroughly immersed I became in its how miraculous it was. It calmed me down. I could start my daily tramp in a foul mood: riled by my partner, anxious about a meeting or wrong-footed by a nightmare; sad or scared or emotionally a little lost. By the time I arrived at wherever I was supposed to be: I was fine. Something about walking gives you perspective.
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.
Taking a 30-minute walk a day is kind of like that proverbial apple: There's a good chance it'll keep the doctor away. From helping you lose weight and de-stress to lowering your blood pressure and reducing your risk of many chronic diseases—going for regular walks is one of the best and easiest things you can do for your health, says Melina B. Jampolis, MD, author of The Doctor on Demand Diet. "Walking is the number one exercise I recommend to most of my patients because it is very easy to do, requires nothing but a pair of tennis shoes, and has tremendous mental and physical benefits," she says. Here's what you can expect when you start walking for just 30 minutes every day, most days of the week.
Part of my walk tutorial is in the original YMCA building in central London – a cavernous gym with incongruous snatches of stained glass reminding exercisers of a higher religious purpose. Every time someone walks past, Hall waspishly critiques their walk (eg: “Look at the bend in his knees and his arms are swinging like hinges”). This becomes more and more enjoyable as her meaning unfolds.

Structurally diverse aromatic chemicals are degraded via the common products such as catechol, protocatechuate, gentisate, hydroquinone (benzene-1,4-diol), homoprotocatechuate, dihydroxyphenyl propionates, and homogentisate (Vaillancourt et al., 2006). The ring cleavage of catechol is performed by two distinct enzymes: intradiol oxygenases (utilize nonheme Fe(III) to cleave the aromatic nucleus ortho to (between) the hydroxyl substituents) and extradiol oxygenases (extradiol dioxygenases utilize non-heme Fe(II) to cleave the aromatic nucleus meta (adjacent) to the hydroxyl substituents) (Harayama and Rekik, 1989).
There are three phases to speeding up: start to use your toes in a more determined way, as if you’re kicking off the back wall of a swimming pool; then concentrate on your hip lift and hark, your glutes will propel you forward; finally, start to swing your arms, concentrating on the elbows – speeding up your arms will naturally make your walk faster.
Start exercising: Many exercise programs say to talk to your doctor before starting. Certain people with specific medical conditions may want to check with their doctor before becoming physically active, however; most people can start a simple walking program without problems. Even those recovering from heart attacks are encouraged to walk treadmills in cardiac rehabilitation programs.
Walking is one of the most rewarding lifelong activities you can choose. While it may not be a huge calorie burner — the average person burns about 100 calories or so per mile — adding more mileage to your day can make a big difference in weight control. According to Harvard Health Watch, one 2009 study found the average person gains about 2.2 pounds a year during middle age. However, over 15 years of research, the study found that individuals who walked regularly gained significantly less weight than those who didn’t.

Though the risks of being sedentary far outweigh the risks of exercise, one should be prudent when beginning an aerobic exercise program. Safety guidelines from the ACSM state that individuals at low or moderate health risk can begin a moderate-intensity exercise plan without a medical exam or exercise stress test, whereas people at high risk should be evaluated by their doctor. You are at high risk if you have:
“While I would love to say that walking can be just as effective of a workout as running, I’m not going to lie to you. In fairness, the two really shouldn’t be compared against each other,” says John Ford, certified exercise physiologist, who runs JKF Fitness & Health in New York City. “Running, due to larger muscle recruitment, greater forces exerted and faster motion capability, will always have the proverbial leg up on walking."
When the weather outside is frightful, many people turn to treadmills. Admittedly, treadmills are boring. Spice up a complete treadmill workout by using elevation to give the sense of a trail. You don't have to follow the preprogrammed courses. Create your own interval training with hills. Make it a mental game. Life isn't automated and your treadmill workout shouldn't be either. Ascend and descend by varying your elevations and speeds.
You know how sometimes it takes a glass of wine or a square (or three) of dark chocolate to blunt the edge of a rough day? Well, going for a walk is a zero-calorie strategy with the same benefits, says Dr. Jampolis. "Research shows that regular walking actually modifies your nervous system so much that you'll experience a decrease in anger and hostility," she says. What's more, when you make your walks social—you stride with, say, your partner, a neighbor, or a good friend—that interaction helps you feel connected, says Dr. Jampolis, which boosts mood. Finally, walking outdoors exposes you to natural sunlight, which can help stave off Seasonal Affective Disorder (SAD)—making it a potential antidote for the winter blues, says Dr. Jampolis.
When running isn't in the cards, walking with added weight might be your next best bet for an effective workout. Research shows that walking on the treadmill while wearing a weighted vest can increase the metabolic costs and relative exercise intensity.The effect of weighted vest walking on metabolic responses and ground reaction forces. Puthoff ML, Darter BJ, Nielsen DH. Medicine and Science in Sports and Exercise, 2006, Jun.;38(4):0195-9131. Similarly, increasing the incline on the treadmill makes for a more effective walking workout. A study showed that walking at a slow speed (1.7 mph) on a treadmill at a six-degree incline can be an effective weight management strategy for obese individuals, and help reduce risk of injury to lower extremity joints.Energetics and biomechanics of inclined treadmill walking in obese adults. Ehlen KA, Reiser RF, Browning RC. Medicine and Science in Sports and Exercise, 2011, Oct.;43(7):1530-0315. And picking up the pace slightly almost always helps. One study found speed walkers had a decreased risk of mortality over their slower counterparts.The relationship of walking intensity to total and cause-specific mortality. Results from the National Walkers' Health Study. Williams PT, Thompson PD. PloS one, 2013, Nov.;8(11):1932-6203.
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.
As you get fit, you burn less calories doing the exact same workout. Shift your walking workout into a higher gear by doing interval training. Start at a warmup pace for a couple minutes and then walk at a brisk pace. Every five minutes, increase your pace to a sprint level, either by speed-walking, running or skipping rope. Maintain this burst of speed for 30 seconds. Return to a slow walk for a minute and then back to your vigorous pace before the next sprint. You dramatically boost your heart rate during the sprints, and it stays raised during the recovery period, resulting in more calories burned.

‘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!
“There are many reasons to walk for exercise,” says Ann Green, M.S., past heptathlon world athlete, yoga teacher and fitness studio owner. “Walking improves fitness, cardiac health, alleviates depression and fatigue, improves mood, creates less stress on joints and reduces pain, can prevent weight gain, reduce risk for cancer and chronic disease, improve endurance, circulation, and posture, and the list goes on…”
If it’s too difficult to walk for 30 minutes at one time, do regular small bouts (10 minutes) three times per day and gradually build up to longer sessions. However, if your goal is to lose weight, you will need to do physical activity for longer than 30 minutes each day. You can still achieve this by starting with smaller bouts of activity throughout the day and increasing these as your fitness improves.
It doesn't take all that much aerobic exercise to accrue lots of fitness and health benefits. There are two physical activity recommendations to choose from in the United States. One is the Surgeon General's "lifestyle" recommendation, where you can accumulate activity and incorporate it into your day (a nice way to save time for busy people), and then there's the formal "workout" recommendation from the American College of Sports Medicine (ACSM).

For most healthy adults, the Department of Health and Human Services recommends at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity, or an equivalent combination of moderate and vigorous aerobic activity. The guidelines suggest that you spread out this exercise during the course of a week. Also aim to do strength training exercises of all major muscle groups at least two times a week.
The American Heart Association recommends that everyone reach a minimum of 30 minutes of some form of cardiovascular exercise 5 to 7 days per week. This can be broken up into 10-minute time periods. This means that taking 3 walks of 10 minutes each would let you reach the recommended minimum guideline for reducing the risk of heart disease, diabetes, hypertension, and high cholesterol. You would also burn the same number of calories as you would if you walked for the full 30 minutes at 1 time.

Walking can also help lower blood pressure. Researchers from Wakayama Medical College, Japan conducted an experiment on individuals with mild hypertension, where 83 participants walked 10,000 steps per day for 12 weeks. At the end of 12 weeks, they showed a significant drop in blood pressure and increased stamina (5). Even if you are unable to complete 10,000 steps per day, you should walk for at least 60 minutes every day to keep your blood pressure levels in check.

There are two physical activity guidelines in the Unites States. The first, the Surgeon General's Report on Physical Activity and Health, is a lifestyle recommendation. That is, you can modify it to fit into your daily routine and activities of daily living. The recommendation is that all adults should accumulate 30 minutes of moderate-intensity activity on most, if not all days of the week. The key words are "accumulate" and "moderate-intensity." Accumulate means that you can do 10-15 minutes at a time and repeat that a couple of times throughout the day; for example, 10 minutes in the morning, 10 minutes at lunch, and 10 minutes around dinner. Moderate intensity is equivalent to feeling "warm and slightly out of breath" when you do it. Recently there has been some controversy about the effectiveness of this guideline and its benefits. At the moment the recommendation stands, but we may hear more about it in the not-too-distant future.
The same goes for intensity, too: Hiking or climbing stairs can actually bring your walking METs burn up to running levels. “Greater muscle forces are required to move faster to accelerate the body up and down, move the limbs faster, and work against gravity,” says Hunter. “Running or walking uphill requires a greater energy, just like lifting weights upwards. It’s as if our body is the weight that we must move to greater heights, so the greater the slope, the greater the energy requirement.”
Getting blood pumping around your system and raising your heart rate provides a perfect workout for your heart and circulation system, and regular walks can even reduce the risk of heart disease and strokes. Through lowering levels of low-density lipoprotein (LDL, the bad cholesterol) and increasing levels of its high-density alternative (HDL, the good cholesterol), you can keep your blood pressure in check. And by helping prevent and control high blood pressure you can reduce your risk of a stroke.
Walking can also help lower blood pressure. Researchers from Wakayama Medical College, Japan conducted an experiment on individuals with mild hypertension, where 83 participants walked 10,000 steps per day for 12 weeks. At the end of 12 weeks, they showed a significant drop in blood pressure and increased stamina (5). Even if you are unable to complete 10,000 steps per day, you should walk for at least 60 minutes every day to keep your blood pressure levels in check.

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.
Both recommendations include aerobic exercise, and your health and fitness will improve if you follow either. Choose the Surgeon General's lifestyle recommendation if you are unable or unwilling to follow the ACSM workout recommendation, and stick with the ACSM recommendation if you're already putting in time at the gym or you like the buzz of vigorous exercise. Of course, incorporating lifestyle activity and formal workouts into your exercise plans will give you the best of both worlds.
"Oxygen consumption" describes the process of muscles extracting, or consuming, oxygen from the blood. Conditioned individuals have higher levels of oxygen consumption than deconditioned individuals ("couch potatoes") due to biological changes in the muscles from chronic exercise training. For example, a deconditioned individual might have a maximal oxygen consumption of 35 milliliters (ml) of oxygen per kilogram of body weight per minute (ml/kg/min), whereas an elite athlete may have a maximal oxygen consumption up to 92 ml/kg/min! Values like this are expressed as VO2 (volume of oxygen consumed) and can be measured with special equipment in a laboratory.
Mental health got me walking in the first instance. I was in my late twenties, and beginning to understand that the love of my life (London) was also my chief tormentor. The stress of the city and the stress of my job as a journalist, got the better of me and I became claustrophobic, which meant I could no longer stand to travel around London’s endless sprawl by Underground. (I’ve since discovered this is incredibly common in Londoners, and God, how transparent we all are! The thing that ferries us to work, aka ground zero on much of our stress; the thing that speeds relentlessly round our city - its logistical arteries - is also the thing we’re likely to fall apart on, and ultimately: resist and refuse.) So I ditched the tube for the bus.
If you're thinking that walking could be a good way of getting fit, losing weight or just keeping you healthy, then this book will tell you how to go about it. If you have already started walking and want to hone your power walking technique, or train for a specific goal (e.g. the London Moonwalk), then this book will tell you everything you need to know. But if you're more into hiking or country walks, then this is not for you.
Walking can also increase your lung capacity. When you walk, you breathe in more oxygen as compared to when you are stationary. This exchange of oxygen and carbon dioxide at a larger volume can help increase your lung capacity, thereby increasing your stamina and exercise performance (16). The best part is, you don’t even have to run. A medium-paced 60-minute walk (with breaks, if you need them!) can do the trick.
But just because it isn’t as time- or energy-efficient as running doesn’t mean you should never look to walking as exercise. Whether you’re running or walking, you can reduce your risk of hypertension, high cholesterol, diabetes, and improve your cardiovascular health, according to data from the National Runners’ Health Study and the National Walkers’ Health Study.
Walking is a great exercise and helps you lose weight. American scientists designed an experiment where obese patients walked together (a concept known as the ‘walking bus’) to their destinations in and around the city. After 8 weeks, their weight was checked, and more than 50% of the participants lost an average of 5 pounds (4). Therefore, it might be a good idea to start walking to and from your nearby destinations, instead of driving your car.
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.
Like walking, running is an inexpensive exercise you can do anywhere at a time that suits you. It is beneficial in helping to improve heart and bone health. Its advantage over walking is that it improves heart fitness and burns kilojoules at a greater rate. It takes roughly an hour for a walker to burn the same number of kilojoules that a runner burns in 30 minutes.
Knowing a bit about the health benefits of walking can also help you stay on track. Not only can walking benefit your heart, bones, and joints, it can also prolong your life. In a 10-year study of 650,000 adults over 40, those who got 75 minutes of moderate activity, like walking, weekly, lived on average, nearly two years longer than their sedentary counterparts. Walkers who logged just over an hour a day gained four and a half years!

These electrons have powerful antioxidant effects that can protect your body from inflammation and its many well-documented health consequences. For example, one scientific review published in the Journal of Environmental and Public Health concluded that grounding (walking barefoot on the earth) could improve a number of health conditions, including the following:14
