Sedentary lifestyles have repeatedly been held partially responsible for the excessive poundage. This is why many groups, including the American Heart Association (AHA), the National Association for Sport & Physical Education (NASPE), and AARP, are now promoting campaigns on how to incorporate physical activity into daily life. And since these organizations recognize the challenge of getting people moving, many have included fitness walking into their recommendations.

One final note. Spin class is interval training. It's done at gyms on special spin cycles with an instructor who barks out orders to increase the intensity and then slow down to catch your breath. It's addictive, and people who do it regularly swear by it. You should already be doing some aerobic exercise and be reasonably conditioned before you try it, but I recommend it if you're looking for one of the toughest workouts around.
Aerobic exercise is any physical activity that makes you sweat, causes you to breathe harder, and gets your heart beating faster than at rest. It strengthens your heart and lungs and trains your cardiovascular system to manage and deliver oxygen more quickly and efficiently throughout your body. Aerobic exercise uses your large muscle groups, is rhythmic in nature, and can be maintained continuously for at least 10 minutes.
OK, so maybe you won’t have the ability to see through walls but you can protect your vision as you age by taking a daily walk, according to a study published in the Journal of Neuroscience. Researchers found that people who did regular aerobic activity had healthier eyeballs and were less likely to suffer from problems like retinal degeneration and age-related vision loss. So even if you aren’t Superman, you’ll still have super sight. Find out what your walking style says about your personality.
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.”
To estimate the amount of energy—remember, energy equals calories—the body uses during physical activity (versus when you’re at rest), scientists use a unit that measures the metabolic equivalent for task (MET). One MET is what your body burns while lounging on the couch watching Netflix. Walking, a "moderate" exercise, uses 3 to 6 METs; running, which is typically classified as "vigorous," uses 6 METs or more.
For joints to work at their best, you need to keep them moving. Regular walking gives knee joints a workout, increases your muscle strength and can keep your bones strong, giving definition to calves, quads, hamstrings and lifting your glutes. Walking not only stimulates and strengthens bones, increases their density and helps maintain healthy joints, it can also fend off conditions such as arthritis and help prevent or alleviate back pain.

“This has all been scientifically proven,” says Hall. “Dr Darren James, research fellow at South Bank University, has done a study showing all this. WalkActive significantly and statistically improves your posture, increases your walking speed by up to 24%, reduces joint impact, joint stress at the knee and at the ankle and improves your body shape.” It is, unmistakably, a fitness programme, as in, you would undertake it for the same reasons as an aerobics class, to lose weight, or at the very least, redistribute it in a more sightly way. I did several 10-minute walks, and while never out of breath, was certainly more tired at the end than I would normally have been.
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.
New research on the endocrine functions of contracting muscles has shown that both aerobic and anaerobic exercise promote the secretion of myokines, with attendant benefits including growth of new tissue, tissue repair, and various anti-inflammatory functions, which in turn reduce the risk of developing various inflammatory diseases. Myokine secretion in turn is dependent on the amount of muscle contracted, and the duration and intensity of contraction. As such, both types of exercise produce endocrine benefits.
With everything else in place – your hips lifted, your neck long and straight – the ball-and-socket joint of the shoulder should be liberated and your arms should shuffle themselves quite freely and intuitively into the right movement pattern. Except that it’s not quite that simple: if you want to use them as agents of acceleration, and you do, you have to use more deliberation. Move your arms across to the centre of your body and then quite far back.
If you haven’t been active for a while, you may find walking is an easy way to get started. But it will also be important to keep your motivation. Begin slowly and gradually increase how much walking you do. You might find it helps to set yourself goals. There are lots of apps that can count your steps, or you could use a pedometer, so your goals can be specific and measurable.
You burn more calories per mile at very low speeds because you are basically stopping and starting with each step and your momentum isn't helping to carry you along. Meanwhile, at very high walking speeds you are using more muscle groups with arm motion and with a racewalking stride. Those extra muscles burn up extra calories with each step. Running may burn more calories per mile as there is an up and down motion lifting your weight off the ground as well as moving it forward."
Picture yourself working out. Are you lifting heavy weights? Stretching your muscles? Or maybe you're performing an activity that causes you to sweat and breathe hard that makes your blood pump through your veins as it carries oxygen to your muscles to keep you going. If you're performing this last activity, then you're engaging in aerobic exercise.

A brisk walk provides us with the best source of natural energy. It boosts circulation and increases oxygen supply to each and every cell in the body, helping you feel more alert and alive. Regular walking should mean you sleep better too. It also serves to bring stiff joints back to life and ease muscle tension. We can all feel sluggish at times, but you can help break that cycle through walking.
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
