Triglycerides are a common form of fat that we digest. Triglycerides are the main ingredient in animal fats and vegetable oils. Elevated levels of triglycerides are a risk factor for heart disease, heart attack, stroke, fatty liver disease, and pancreatitis. Elevated levels of triglycerides are also associated with diseases like diabetes, kidney disease, and medications (for example, diuretics, birth control pills, and beta blockers). Dietary changes, and medication if necessary can help lower triglyceride blood levels.
So how many calories are you really torching? “For an average height woman of 130 pounds walking at a typical speed of 2.9 miles per hour, the total energy expended to walk one mile would be 81 kilocalories (kilocalories is the proper name for what most people refer to as calories),” says study co-author Peter Weyand, Ph.D., a biomechanics professor and director of the Locomotor Performance Laboratory at Southern Methodist University. To compare: The old equation predicts you'll burn just 68 calories per mile at 2.9 miles per hour, says Weyand. “For a faster walk of four miles per hour or so, the number of kcals burned increases to about 95 per mile,” he says. 
It’s official: Walking is as good for your brain as it is for your body. A comprehensive study of the effects of exercise on the brain found that it benefits all aspects of your mind, including memory, cognition, learning, reading and it even increases the size of your brain to boot. Even better, walking protects your brain by lessening your risk of getting cognitive illnesses like Alzheimer’s disease and dementia. Find out why walking at work is even better than a standing desk.
I walked along my bus route, assuming that sooner or later, my arrival at another bus stop would coincide with the arrival of my bus. But it didn’t. So I walked some more, eventually making it to work, a mere 20 minutes later than I normally would have, calmer than I might have anticipated, and feeling like I’d accomplished something vaguely mammoth before 10am. I also felt liberated. Who wants to be enslaved to their public transport systems, beholden to the schedules, the whims and capriciousness. Suddenly, I had another option.
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.
Once you have become accustomed to a regular pattern of workouts (as opposed to merely walks), you can achieve a higher level of physical fitness not merely by increasing the distance of the workouts but also by varying the distance from day to day. “You don’t always need to walk the same course or the same distance,” Fenton says. “Perhaps once or twice a week, set aside time for slightly longer walks, or much longer ones on the weekends.” If your goal is losing weight, the more you walk the more calories you’ll burn. Walking, like running, burns approximately 100 calories for every mile covered.
Dr. Tannenberg offers another tip for incorporating intervals into your workout: “Create a new playlist with upbeat songs followed by slower songs. Alternate the songs on your playlist. When you are walking and hear a faster song, you increase your pace. When the slower song comes on, you slow down the pace a bit. This is an easy way to make your normal morning walk an interval workout.”
Interval training is more intense than simple aerobic training. It's a very effective way to increase your fitness level (remember stroke volume and mitochondria activity!), but it's tough, and so I recommend holding off until you build up to 20-30 minutes of aerobic exercise. The idea to intervals is to set up work to active-rest ratios (work:active-rest), and as you get more fit, decrease the active-rest interval and increase the work interval. The work interval of the ratio is a speed that is faster than what you usually do, and the active-rest interval is your usual speed. To do it, you start at your usual speed for five to eight minutes, then increase the speed to the work interval for one to three minutes, then slow down to your usual speed for a few minutes to catch your breath (this is the active-rest interval), and then you repeat the cycling for the duration of your workout.
The list of studies that show that aerobic exercise prevents or reduces the occurrence of cardiovascular disease is so long that it would take this entire article and probably five others just like it to review all of the research. One of the most important is one of the earliest. In a study of more than 13,000 men and women, it was shown that the least fit individuals had much higher rates of cardiovascular disease than fit individuals -- in some cases, the risk was twice as high. Aerobic exercise works in many ways to prevent heart disease; two of the most important are by reducing blood pressure and allowing blood vessels to be more compliant (more compliant means that they become less stiff and it's less likely for fat to accumulate and clog up the vessels). Results like these have been proven over and over again.
"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.
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.
On the other hand, some people like to know with more precision how their body is doing during exercise. If that's the case for you, then taking your heart rate during exercise and using a target heart rate training zone might be just the ticket. Target heart rate zones range anywhere from 50% to 100% of your maximum heart rate (your maximum heart rate is based on your age). Aerobic exercise is anything less than 85%, and anaerobic exercise is anything above that. A nice starting point for a sedentary individual is somewhere in the range from 50% to 65% (you can always increase as you get more fit) and 65% to 85% for more conditioned individuals.

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.
In 2007, Circulation, the journal of the American Heart Association, published an updated report on physical activity and public health. In order to make a recommendation on the amount of exercise necessary to benefit America's health, an expert panel of scientists, including physicians, epidemiologists, exercise scientists, and public-health specialists reviewed research on physical activity and the impact of exercise on health.
Although the programme started in earnest in 2010, Hall was cooking it up from the time she had to have an appendix operation, while pregnant, four years before that: a graduate from Loughborough University’s famous sports science degree, pioneer of American corporate weight management programmes, she was suddenly in a wheelchair and steadily gaining weight. “It came from a very personal space to heal myself, improve my posture, safeguard my joints, keep my sanity,” she says. WalkActive grew, at first informally when she integrated it into personal training programmes, and then into a system on its own, for which there is now an app, a book and audio coaching, as well as licensed trainers all over the UK. It is full-time work, changing the way people walk.
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.
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.

This one may seem obvious, but it's certainly a happy benefit for those who start walking regularly, says Dr. Jampolis. "As you continue to walk, you may notice your pants begin to fit more loosely around your midsection, even if the number on the scale isn't moving much," she says. "That's because regular walking can help improve your body's response to insulin, which can help reduce belly fat." Ariel Iasevoli, a personal trainer at Crunch gyms in New York City, adds that walking every day is one of the most effective low-impact ways to mobilize fat and positively alter body composition. "Daily walking increases metabolism by burning extra calories and by preventing muscle loss, which is particularly important as we get older," says Iasevoli. The best part? You don't have to slog it out on a treadmill at the gym to see these benefits. "One of my clients reduced her body fat by 2% in just one month by walking home from work each day, which was just under a mile," she says.
Walking is a low-cost and effective form of exercise. However, the wrong type of shoe or walking action can cause foot or shin pain, blisters and injuries to soft tissue. Make sure your shoes are comfortable, with appropriate heel and arch supports. Take light, easy steps and make sure your heel touches down before your toes. Whenever possible, walk on grass rather than concrete to help absorb the impact.
You ought to walk as if you’re wearing very long diamond earrings, and you want everybody to be able to see the diamonds, rather than having them sitting on your collar bones. When your head is forward, your shoulder girdle also rolls forward, which gives you an unappealing hunch, but more importantly, encourages the shoulder joint, which is a ball-and-socket joint, to behave like a hinge joint. This makes your arms as good as useless in the business of moving you forward, but also stiffens the shoulders, which makes the spine rigid. The spine should be able to rotate. I don’t know why, but I accept as a general principle that if your skeleton is capable of a range of movements that you never do, that’s a bad thing.
Becoming taut is all in the hip lift. “You should imagine you’re putting on a very expensive pair of tights,” Hall said, “inching up each leg very carefully, ending at the hips.” I’m actually learning quite a bit about how to put on tights, but still baffled about hip lifts. “May I touch you?” she says. Sure, I say. She physically lifts my hips up, away from my legs. Once I know what it should feel like, I can do it myself, but only if I think extremely hard.

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.

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.
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.

Walking might not have the same visual appeal as high-intensity interval training or step aerobics, but this simple exercise can be an efficient way to burn calories. Whether you're anxious to shed a few pounds or are just keen to avoid the middle-age spread, walking several times per week (in combination with a healthy diet, of course) can burn thousands of calories to help keep the excess pounds at bay. Consult your doctor before beginning any exercise regimen, even a light one.

If it’s too hot to walk or run, swimming can be a cool way to get fit. It’s a low-cost workout for the whole body especially the muscles of the back, shoulder and arms and improves flexibility as well. It’s a good way to exercise if you’re overweight, pregnant or have joint problems as the water helps support your weight and can reduce the pressure on your joints. The risk of injury to muscles, ligaments or joints is also low.

It should be noted that the MET approach was designed to build a classification system of different activities for research purposes - MET values "do not estimate the energy cost of physical activity in individuals in ways that account for differences in body mass, adiposity, age, sex, efficiency of movement, geographic and environmental conditions in which the activities are performed. Thus, individual differences in energy expenditure for the same activity can be large and the true energy cost for an individual may or may not be close to the stated mean MET level as presented in the Compendium." (as quoted from the main page of the Compendium of Physical Activities)
3. It reduces the risk of developing breast cancer. Researchers already know that any kind of physical activity blunts the risk of breast cancer. But an American Cancer Society study that zeroed in on walking found that women who walked seven or more hours a week had a 14% lower risk of breast cancer than those who walked three hours or fewer per week. And walking provided this protection even for the women with breast cancer risk factors, such as being overweight or using supplemental hormones.
I mentioned that fat and carbohydrate are the fuels our muscles burn. The difference between them is that fat is high-test; it contains 9 calories per gram whereas carbohydrate has only 4, and so you get more energy and can go farther on a gram of fat than on a gram of carbohydrate. You want to burn fat because it's such an efficient fuel, plus it's nice to lose some of your excess fat! The catch is that you need more oxygen to burn fat because it's denser than carbohydrate. The good news is that your body gets better at using oxygen and burning fat when you do regular aerobic exercise; like I described, your heart pumps more blood, your muscles consume more oxygen, and you have more mitochondria.
The third thing I noticed, was how walking reaffirmed my love for where I loved. When you wander daily around your locale, you start to look at it properly; when you do that, you notice how devastatingly beautiful it is. How weird, how sweet, how contrary, how chic. I saw hidden architectural loveliness and hilarious graffiti; outrageously stylish tiling on the exterior of ancient pubs, unutterably picturesque, Dickensian cut-throughs and alleyways. I saw more of the sky, more often, than I’d ever seen before.
