Walking is an accessible and easy way for us all to get more active. Brisk walking that raises your heart rate and makes you warm and slightly breathless is a great form of aerobic exercise. Doing this regularly helps you to get fitter so you will find it easier to be more active and get tired less quickly. You may feel more tired in the first week or two after you start. But if you keep it up, you’ll probably find you soon have more energy than when you were inactive.
Fitness trackers and fitness equipment can tally your calories burned while exercising, but they’re not always accurate. “Using a variety of sources and taking a ‘midpoint’ might help keep you honest,” says Hilaton. “I think it is important to keep in mind that all of these estimates of calories burned are just that: estimates. There are a lot of variables that go into the actual number of calories burned by any given individual in any exercise beyond speed and duration.” For a starting point, calculate your numbers with our Calories Burned Running Calculator.
As we age, our risk of unsightly varicose veins increases—it's just not fair. However, walking is a proven way to prevent those unsightly lines from developing, says Luis Navarro, MD, founder, and director of The Vein Treatment Center in New York City. "The venous system includes a circulatory section known as 'the second heart,' which is formed by muscles, veins, and valves located in our calf and foot," he explains. "This system works to push blood back up to the heart and lungs—and walking strengthens this secondary circulatory system by strengthening and preserving leg muscle, which boosts healthy blood flow." If you already suffer from varicose veins, daily walking can help ease related swelling and restlessness in your legs, says Dr. Navarro. "Also, if you are genetically predisposed to have varicose and/or spider veins, walking daily can help delay the onset."
There ins and outs of different methods of measuring your walking speed. Cell phone apps and running speedometer watches use GPS, which can be inaccurate and won't work indoors on a treadmill. Fitness bands and pedometers may use your step cadence, which can vary if your stride length is different from what is expected. You can verify the accuracy of these readings by walking a measured mile and calculating your walking speed and pace.
This is a good aerobic workout that also boosts upper body strength — and helps you let off steam. Boxing classes are widely available in many gyms. Some classes involve sparring with a partner — you take it in turns to hold a pad or pads while the other person punches them while wearing boxing mitts. Others involve no mitts or pads, just air punching and other moves that simulate boxing training. You can also use a punching bag either at the gym or in your own home.
For a walking surface grade between -5% to +5% inclusive, this walking calorie burn calculator is based on equations (shown below) derived by ShapeSense.com from experimental data displayed in Figure 3 of the study titled "Energy Cost of Running," by R Margaria, P Cerretelli, P Aghemo, and G Sassi (note that the data on walking energy expenditure was originally printed in the study titled "Sulla fisiologia, e specialmente sul consumo energetico, della marcia e della corsa a varie velocita ed inclinazioni del terreno," by R. Margaria). The experimental data gathered by Margaria measured calorie burn of subjects walking at various speeds and on various surface grades. It was found that there is a non-linear relationship between walking speed and rate of calorie burn, as opposed to calorie burn while running, which displays a linear relationship between speed and rate of calorie burn.
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.
When bones thin too much – a disease called osteoporosis – you become more susceptible to fractures. In young people, whose bones remodel and rebuild with ease, this might not be too concerning. However, if you are an older individual or have compromised bone density, fractures can significantly affect quality of life and impact your ability to perform the daily activities you need to remain independent.

An analysis of studies on walking showed it improves aerobic fitness - which is technically the ability of the heart to get oxygen to our muscles and how effectively our muscles use that oxygen. But to be effective, walking needs to be of at least moderate intensity, which means an intensity where you’re able to notice your breathing but can carry on a conversation without noticeable pauses between words. For many, this is a brisk walk.

The question of BP lowering with aerobic exercise in type 2 diabetics has been studied. In the Early Activity in Type 2 Diabetes (ACTID) trial, 593 newly diagnosed diabetics were randomized to use of a pedometer in a program that included intense counseling or standard or intense dietary advice.46 There was no difference in SBP or DBP after 6 or 12 months, even though the participants using pedometers increased their steps by 17% on average. Whether the exercise was merely of too low a “dose” to be effective is unclear. There may be some male-female differences in BP response to aerobic exercise, with women exhibiting BP lowering with resistance compared with aerobic exercise and men responding similarly to both types of exercise.47 The 2013 AHA Scientific Statement recommends at least 30 minutes of moderate intensity aerobic exercise per day most days of the week.2 The authors assigned dynamic aerobic exercise a Class I, level of evidence A recommendation in those for whom it is not contraindicated. Our review of the evidence since 2013, as well as that from another group, confirm these recommendations.41,48 Whether or not high versus moderate (or interval) intensity training is optimal for BP-lowering as well as other aspects of the dose-response effect (i.e., ideal duration of cumulative exercise per week) and the potential impact of different types of aerobic activity requires further investigation.
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.
Your morning cup of java could actually aid your weight loss efforts. According to the results of a 1990 study in the American Journal of Clinical Nutrition, caffeine consumption can increase calorie burn. A second study, published in a 1994 edition of the International Journal of Obesity, found that the consumption of 200 milligrams of caffeine increased calorie burn by 6.7 percent during a three hour period.
Your local gym will provide a wide variety of aerobic options, such as treadmills, cross trainers, exercise bikes, stairmasters, rowing and ski machines so that you can just switch on and get started with your workout. It can be a good idea to diversify between different machines and different speeds/levels of resistance as your body can get used to a certain routine and after a number of sessions the same routine will not work your heart and lungs as much as it once did.
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.
Can you up those numbers? The more you weigh, the more calories you’ll burn, no matter the activity—that’s because it takes more energy to move more weight. If you’re specifically looking to up calorie burn, adding a 20-pound weighted vest would up your calorie burn to 8.7 and 15.1 per minute for walking and running, respectively. It’s simple physics: “The majority of calories burned in running [or walking] comes from supporting body weight while moving up and down,” says Hunter. “With more weight, there will be a greater energy cost in doing this due to a greater gravitational force.”
To start losing weight, you need to burn about 600 calories a day more than you’re eating and drinking, and for that, you might have to up your speed. You can burn off twice as many calories by walking at 4 miles an hour (6.5 kilometres per hour) than you can at half that speed. Walking also increases muscle mass and tone. In short, the more muscle you have, the faster your metabolism, so the more calories you burn off.

If you are new to walking, you cannot walk for long distances immediately. So, break up your walking routine. Start by walking 10 minutes every day. Gradually increase this duration to 30 minutes a day. Then, you can walk 30 minutes in the morning and 30 minutes in the evening. You should also gradually increase the pace of your walking. When you are comfortable enough, you can try to walk 10,000 steps a day. Take necessary breaks in between. And, of course, keep yourself hydrated.
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.
