how to stretch your feet
The muscles in your feet have a close relationship with those in your legs: Pain in the leg muscles makes it hard for foot muscles to (comfortably) do their job, and vice versa. Also, many stretching exercises benefit both the feet and the lower legs. Rochelle Rice Cutro, a New York City exercise instructor and creator of a fitness lifestyle program called "In Fitness and In Health," suggests these stretches for this stressed-out area of the body.
Note: These exercises are best practiced at home, but see the previous page for easy stretches you can do while sitting behind a desk. Lunge: From a standing position, with your feet together and toes pointing forward,
"lunge" forward with your right foot. Keep your knees bent and your chest up as you lunge. Be sure your right heel strikes the floor before the rest of the foot. And be sure that you keep your right knee aligned above your right ankle; do not bend your right knee so far that it extends forward beyond the ankle. Return to the normal standing position. Repeat 11 more times; then lunge 12 times with the left foot. To increase the intensity of this stretch, do lunges onto a step or small platform.
Tendon Stretch: Stand with both feet on a step or a phone book, with your heels extending beyond the edge of the step. You may want to hold onto something to keep your balance as you shift your weight toward your heels and gently stretch the muscles and tendons in the back your lower leg.
Towel Lift: Sit on the floor with your legs extended in front of you. Bend your left knee and put your left foot flat on the floor. Place a towel around your right ankle. Grasping the ends of the towel, use it to pull your right leg up. Keep your right leg straight and keep your buttocks on the floor as you do so. Hold the stretch for several seconds; then lower your leg to the floor. Repeat with the left leg.
"V" Stretch: Sit on the floor and place your legs out in front of you in a "V" shape. Turn your torso to the right and place your hands on the floor -- one hand on either side of your right thigh. Roll your left hip and your left toes inward, so that the inside of your left foot is resting on the floor and the toes of your left foot are pointing toward your right leg. You should feel a stretch in the inner side of your left thigh. Release the stretch, and then repeat the exercise in the opposite direction, with your hands next to your left thigh and your torso turned to the left.
Knee Hug: Sit on the floor with your legs out in front of you. Cross your right leg over your left, with your right knee bent. Hug your right leg to your chest. After putting your right leg back on the floor, cross your left leg over and repeat the hug.
Quad Stretch: Stand behind a chair with your left hand on the back of the chair to help you maintain your balance. Bend your right knee, raise your right foot up behind you, and grasp the right foot with your right hand. Gently pull upward on the foot until it reaches the buttocks. Hold it there for several seconds. You should feel a stretch in the large muscle at the front of your thigh. (Do not arch your back as you do this exercise.) Place your right foot back on the floor, and repeat the stretch with the left foot.
Crouch: Stand in front of a stable chair and hold your arms straight out in front of you (parallel to the floor). Gradually begin to sit down -- but stop before your buttocks touch the chair. Your weight should be on your heels; your arms should help you maintain your balance. Stand up again slowly and repeat. Rest, then do another two sets.
Towel Scrunch: Sit on a chair and place your bare feet on the floor. Pretend you have a towel under your toes; draw the towel in toward your heels by scrunching your toes. Then reverse the exercise by using your toes to push the imaginary towel out and away from the heel. Do this ten times with each foot.
Towel Scoop: Sit on a chair and place your bare feet on the floor. Use the outer part of your foot to scoop the imaginary towel in toward your arches. Then use the inner part of your foot to smooth the towel back out. Do this ten times with each foot.
Warning!As you do these exercises, remember to stretch only to the point of mild tension, not to the point of pain. Also, do not bounce when performing the exercises. Use a slow, steady movement.
All this stretching may have you feeling like a workout, and it's important to take care of your feet while exercising, too.
how to re energize your feet
Foot Relaxer: Start by relaxing and loosening the muscles and joints of your feet by shaking them (the same way you'd shake out cramped muscles in your fingers and hands). Then wiggle your toes, first on one foot, then the other.
Foot Press: With your feet on the floor, take your shoes off and place one foot on top of the other. Press the top one down toward the floor while pulling up with the bottom foot -- but don't let your feet separate. This can be a little tricky!
Toe Tap: With your feet on the floor, tap your toes, or pretend that you're pressing down on a pedal, first with one foot, then with the other foot. Toe Writing: With your feet on the floor and your shoes off, use your toes to "write" the letters of the alphabet, from A to Z, on the floor.
The Grip: With your feet on the floor and your shoes off, try picking up a pencil or pen with your toes. Or try picking up a marble (if you happen to have one lying around).
Page Rippler: With your feet on the floor and your shoes off, place a phone book under your feet, with its binding facing your body. Curl your toes over the far edge and try to ripple the pages.Once you have revitalized your feet with these seated exercises, you might want to massage your feet a bit. It's a great way to cap off your mini foot workout. See the foot massage page in this article for tips, or try the suggestions below.
Roller Massage: If you're sitting at home with your shoes off, place a rolling pin under one foot. Roll back and forth on the pin with that foot; then do the same with the other foot. This is a way of giving yourself a foot massage without pulling your feet into your lap or getting down on the floor. If you like this, you might even take a rolling pin to the office; then, several times throughout the day, take your shoes off and "roll" the tension out of your feet. This "roller massage" will also work with a tall, narrow bottle. Some people use smaller "rollers" including golf balls and even marbles.
Flex and Point: Try this at home or at the office if there's a way you can prop your legs up so that they're facing straight out in front of you and are parallel to the floor. (In the office, you might prop them on a high stool or another chair; if you're sitting on the couch at home, use the coffee table.) Point your toes forward, like a ballerina pointing her extended foot, and hold that position for 15 seconds. Then relax your toes and reposition your feet so that your toes are pointing toward the ceiling. Repeat this routine -- flex and point ahead of you, then relax and point to the ceiling -- ten times.
Curl and Turn: With your legs propped up in front of you and parallel to the floor, curl your toes, and then (keeping your heels on the surface where they're propped) turn your feet inward. Hold this position for five seconds. Then allow your toes and feet to return to their former, relaxed position.
Purse Lift: [For women] With your back pressed straight against the back of the chair, drape the strap of your purse over one foot. Keeping your knee bent, raise your foot until the purse hangs suspended in the air. Hold that position as long as you can, then lower your foot. Switch the purse to the other foot and repeat the exercise.
how to care for your feet !!! ever needed

However, there are some situations when caring for your feet on your own is not advised. When serious injury occurs or an emergency arises, you should visit a podiatrist -- or even the emergency room. People who have ongoing circulation problems or diabetes should also consult a doctor where any foot problems are concerned. Here's why: Circulation problems are often associated with older feet, but the fact is that anyone can have such problems. When there's not enough blood flowing to your feet, you may experience tingling, numbness, cramping, and discoloration of the skin and toenails. Everyday circumstances can restrict blood flow: when feet get cold outdoors or in cold water; when shoes, stockings, or undergarments are too tight; even when you've sat too long with your legs crossed. Smoking reduces circulation to all parts of the body, as does drinking too much coffee or caffeinated soda (both nicotine and caffeine constrict blood vessels). And if you are under severe stress, your nerves can constrict your small blood vessels, lessening their ability to carry blood. Some nervous brides and grooms really do have "cold feet"!

Other people have ongoing medical conditions, such as diabetes, that cause sluggish circulation. In addition, for most of us, a cut or blister is an annoying but relatively minor foot problem. For a diabetic, these "little" wounds can have serious consequences. Diabetics' feet are at two general disadvantages that can lead to specific, serious foot problems. In addition to reduced circulation, a loss of feeling in the foot, called neuropathy, can prevent diabetics from feeling the small aches and pains that normally signal to us that we've been cut or bruised. As a result, minor problems can go unnoticed and untreated, and infection may develop.
One of the best ways to avoid trouble with your feet is to exercise preventive care

how to strengthen your shoulder muscle
The following exercises show examples of moves targeting the shoulders -- the front, middle and rear deltoids as well as the rotator cuff muscles. Choose a variety of exercises to target each part of the shoulders for a well-rounded routine. Click on the pictures and links to view detailed instructions or to see a larger picture. To work these exercises into a routine:
- Beginners: Choose 1 to 2 exercises, 1 to 2 sets of 12 to 16 reps
- Inter/Adv: Choose an exercise from each column for 2 to 3 sets of 8 to 12 reps, resting between sets
- UUse enough weight that you can ONLY complete the desired number of reps
Overhead Presses Overhead presses work the major muscles of the shoulder, with a focus on the middle deltoid and tricep. To do a basic overhead press, stand (or sit) holding weights with elbows bent and hands at eye level. Push weight over head without arching the back and lower back to start. | Front, Side, Rear Raises Front, side and rear raises target each part of of the shoulders as well as the upper back. When doing shoulder raises, only lift the weight up to shoulder level. When doing rear flies, lead with the side of the hand and imagine you're making a smiley face as you lift the arms up. | Rotations/Upright Rows Shoulder rotations work the rotator cuff and usually require smaller range of motion and light weight to avoid injury. Upright rows work the middle deltoid as well as the upper back and bicep muscles. If you have shoulder problems, you may want to avoid these exercises. |

Overhead Press with Dumbbells | Lateral Raise | Internal Rotation |
Arnold Press | Rear Lateral Raise | Upright Rows |
Walking and Disease
Walking and Disease
The simple act of walking can decrease your chances for contracting diseases like diabetes, cancer, and osteoporosis.
A regular walking program can help you reduce your chances of developing Type II, or non-insulin-dependent, diabetes. Because a program of regular exercise is extremely helpful in weight management, by reducing the risk of obesity, you also reduce the risk of becoming diabetic.
Exercise improves your muscles' ability to respond to insulin and take up more glucose. It can help you reduce your risk of developing diabetes, as well as manage the disease if you already have it. In addition to regular exercise and proper diet, careful monitoring of blood glucose levels is important to diabetes management.
Because of the positive impact of exercise on the immune system, exercise can reduce your overall cancer risk. For site-specific cancers, exercise may have a different impact on cancer development.
Regular physical activity has been shown to lower the risk of both breast cancer and colon cancer. The mechanism for reduction of breast cancer risk may be due to hormone level changes and reduced body fat that result from exercise. Colon cancer risk may be lowered due to reduced intestinal transit time, thus decreasing the time that possible carcinogens may come in contact with the colon wall.
Osteoporosis is a relatively common disorder characterized by a decrease in the calcium content of the bones, which leaves them thin and susceptible to fracture. The causes of osteoporosis are largely unknown. However, the chances of acquiring the condition seem to increase dramatically with age, especially for women.
One prevailing theory maintains that osteoporosis results from a loss of the female hormone estrogen, which affects the calcium content of the bones. Menopause (cessation of menstruation) may lead to osteoporosis because the body's production of estrogen is greatly reduced after that time. Almost one-third of all women over the age of 60 experience osteoporosis to some extent.
People who are inactive, either by choice or due to confinement because of illness, seem more susceptible to the disorder. A diet deficient in calcium (which promotes bone development) may also contribute to osteoporosis.
Physicians urge their female patients to engage in regular weight-bearing exercise, such as walking, and resistance exercise (such as weight training) throughout their lives; in these exercises, the bones and muscles must work against gravity or another force to support the body (as opposed to swimming, in which the water supports the body), so they help to build and strengthen bones as well as muscles and thus help prevent the frailty caused by osteoporosis.
Likewise, patients who suffer from osteoporosis are typically encouraged to follow an exercise program that will strengthen the muscles supporting their weakened bones; such individuals, however, need to seek the advice of their doctor and perhaps an exercise physiologist before beginning any exercise program and should avoid certain activities, such as lifting heavy objects, in order to protect the bones in the spinal column.
Walking and other exercise can affect your total quality of life, too. Read on to discover how walking can help you sleep -- and give you more energy.

Walking and High Blood Pressure
Walking and High Blood Pressure
Regular exercise, like walking, is a proven way to reduce high blood pressure Because you can go for years without knowing you have the condition, high blood pressure has been called the "silent killer."
If you have high blood pressure, and you don't control it, your heart has to work progressively harder to pump blood through your arteries. Your heart may enlarge, and you'll be at an increased risk for heart attacks, stroke, kidney failure, and atherosclerosis (buildup of plaque in the arteries).
Men have a greater risk of high blood pressure than women until age 55, when their respective risks become about the same. At age 75 and older, women are more likely to develop high blood pressure than men.
People who have high blood pressure should work with their doctor to control it. Eating a proper diet, losing weight, exercising regularly, restricting salt (sodium) intake, and following a program of medication may all be prescribed to lower blood pressure and keep it within healthy limits.
Your blood pressure is a measurement of the pressure of the blood flow in your arteries. Your systolic blood pressure, the higher number, tells you the pressure in your arteries when your heart is contracting and pumping blood out into the body. Your diastolic blood pressure, the lower number, is the pressure in the arteries when the heart is relaxed.
During exercise, your systolic blood pressure increases to improve blood flow, thus increasing available oxygen to the working muscles. Your blood vessels may also become more relaxed, or dilated, to allow for the increased blood flow. This may mean a slight lowering of your diastolic blood pressure.
Right after exercise, your blood pressure is probably a little bit lower than before you started. This is a very positive response of the body. Regular exercise has been shown to result in a reduction in blood pressure for those who may be hypertensive.
It is interesting to note that when you stop exercising regularly, your blood pressure will return to its prior level, usually within a week. Therefore, you cannot "bank" your exercise, building up an account, so you can take time off. The benefits of exercise are reduced when you cease to partake of it on a regular basis. A small dose of exercise done over a long period of time has a much better result than a large amount done irregularly.
Just like you wouldn't want to overdose on medicine, neither would you want to overdose on exercise. If you miss a day or two, don't try to make up for it by overdoing it. Just start your routine again, perhaps even cutting back a little at first, depending upon how much time you took off.
So far we've looked at how walking can help prevent cardiovascular problems. But it can also lower the risk of contracting certain diseases.walking and heart disease
Walking and Heart Disease
Walking can help ward off a killer: heart disease. Heart disease is the number one threat to America's health. In fact, 50% of all deaths occurring in the United States each year can be directly attributed to this killer. Scientific evidence suggests that participation in regular physical activity results in a lower risk of developing heart disease.
In addition, regular exercise helps individuals recovering from heart attacks and bypass surgery and lowers their risk of suffering a second heart attack.
Heart disease is caused by the build-up of plaque in the coronary arteries. When too much plaque accumulates, blood flow to the heart is decreased. Without enough blood supply, the heart muscle may not get enough oxygen to do its work. Chest pain caused by lack of oxygen to the heart muscle is called angina.
People who have angina sometimes use a medication known as nitroglycerin that causes the coronary arteries to dilate, thus increasing the blood flow to the heart and reducing chest pain.
When ischemia (lack of blood flow to the heart) is caused by a complete blockage of an artery, part of the heart muscle can die. (Complete blockages are often the result of a blood clot that gets caught in a narrow space in an artery that already has a large build-up of plaque.) This is called a myocardial infarction, also known as a heart attack. Sometimes blockages occur in blood vessels that supply blood to the brain. An infarction in the vessels feeding the brain is called a stroke.
Reducing the risk of heart disease may be your motivation to exercise regularly, particularly if you have risk factors you cannot control. Age and family history of heart disease are both strong risk factors, neither of which are preventable. So if you have had a close family member, such as a parent or sibling, who developed heart disease before the age of sixty, you too are at increased risk. Becoming more physically active and increasing your physical fitness will improve your chances of living a longer, healthier life.
Physical Inactivity
Physical inactivity is also a risk factor for coronary heart disease. When lack of exercise is combined with overeating, excess weight and increased blood cholesterol levels can result -- and these conditions unquestionably contribute to the risk of heart disease as well.
Regular exercise has been shown to reduce your resting heart rate, thus decreasing the overall workload on the heart. Some studies show that exercise, combined with a low-fat diet and stress management, can even reduce plaques that have built up in the vessel walls.
Regular aerobic exercise plays a significant role in preventing heart and blood vessel disease. The American Heart Association recommends moderate-intensity aerobic (endurance) physical activity for a minimum of 30 minutes, five days a week, to promote cardiovascular fitness. Such activities could include aerobics, jogging, running, and swimming and sports such as tennis, racquetball, and soccer.
Even modest levels of low-intensity physical activity are beneficial if done regularly and long term. Such activities include walking for pleasure, gardening, and housework. Middle-aged or older people should seek medical advice before they start to significantly increase their physical activity.
Cholesterol
Everyone needs a certain amount of cholesterol to build cell membranes and maintain health. But too much of these blood lipids -- especially the "bad" low-density lipoprotein (LDL) variety -- can raise your risk for heart disease and stroke. Too little "good" cholesterol (high-density lipoprotein, or HDL), which helps remove fats from the bloodstream, can also pose a problem.
The risk of coronary heart disease rises as blood cholesterol levels increase.
If you smoke cigarettes or have high blood pressure, your risk for heart disease increases even more. A person's cholesterol level can also be affected by age, sex, heredity, and diet.
Nearly everyone can lower their cardiovascular disease risk by eating foods low in saturated fat and adopting an overall healthier lifestyle. Based on large population studies, total blood cholesterol levels below 200 mg/dl (milligrams per deciliter) in middle-aged adults seem to indicate a relatively low risk of coronary heart disease. A level of 240 mg/dl and over approximately doubles the risk. Blood cholesterol levels from 200-239 mg/dl indicate moderate and increasing risk.
High blood pressure is another risk factor for heart attack and strokeoverview...!!! in this this article walking
Walking is widely recommended for its health benefits. According to a recent U.S. Surgeon General report on physical activity and health in America, more than half of the U.S. population does not participate regularly in any type of exercise. That physical inactivity can lead to poor health.

It is increasingly obvious that one of the best ways to maintain good health is through physical activity. Regular participation in exercise has been shown to be helpful in the prevention of such killers as heart disease, cancer, and diabetes. Exercise also helps to control weight. (According to the latest research, one out of three Americans is obese.)
And because exercise helps to strengthen muscles and bones, it can even decrease your risk of developing diseases such as osteoporosis and arthritis.
Some of the most interesting and overwhelming evidence supporting the need to be physically active is from the research being conducted at the Cooper Institute for Aerobics Research in Dallas, Texas. Dr. Kenneth Cooper, known as the "father of aerobics," founded the Cooper Clinic in the early 1970s to investigate the effects of physical activity and fitness on health and longevity and to help people develop healthy lifestyles.
In July 1996, research from the Cooper Institute showed that participating in moderate to high levels of physical activity reduced the risk of dying from any given cause. This held true regardless of other risk factors. In other words, even if an individual suffers from high blood pressure or obesity, the chances of dying are lessened by maintaining at least a moderate level of fitness. This is remarkably good news, especially for individuals who have hereditary risk factors such as a family history of heart disease.
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.
Their conclusion was the same as the plea issued by the Surgeon General: "Every U.S. adult should accumulate 30 minutes or more of moderate-intensity physical activity on most, or preferably all, days of the week." The researchers determined that intermittent as well as sustained activity can be beneficial. In other words, on days when you can't fit in a 30-minute walk, you can still garner fitness benefits by taking two or more shorter walks squeezed in throughout the day.
This may seem somewhat confusing to those of you who are well acquainted with previous recommendations to exercise for a sustained period of 20 to 60 minutes. The Surgeon General's report is not meant to overshadow or replace these previously recommended exercise guidelines.
Exercising for a sustained period of time is still the best way we know to make improvements in your cardiorespiratory fitness. But for many, exercising for long periods of time can be intimidating. And most of us experience days when unforeseen events throw off our schedules and prevent us from having a solid block of time for exercise.
Significant health benefits can be realized by simply ceasing to sit and starting to move. The risk of developing heart disease, high blood pressure, non-insulin-dependent diabetes, and colon and breast cancers can be reduced just by becoming more physically active.

how to calculate body fat
There are three main ways to calculate body fat:
- Home Body Fat Scales
- Skinfold Calipers (Callipers)
- Hydrostatic Weighing
Each of these body fat calculation methods has advantages and disadvantages.
Using Home Body Fat Scales to Measure Body Fat
Body fat scales claim to measure body fat quickly and conveniently. These body fat scales use the Bioelectrical Impedance method to measure your body fat percentage. A low-level electrical current is passed through your body and the "impedance", or opposition to the flow of current, is measured. The result is used in conjunction with your weight and other factors to determine your body fat percentage. Unfortunately, your body's "impedance level" can be altered by many factors besides body fat. For instance, the amount of water in your body, your skin temperature and recent physical activity can all adversely affect the results.So only by following strict rules can you hope to get an accurate measurement of your body fat using these scales. The most important rules to observe in order to make a more accurate calculation of your body fat are:
- Don't eat or drink for 4 hours before the body fat measurement test.
- Don't exercise for 12 hours before the test.
Notes:
- Some studies have shown variances as high as 8 percent when using the bioelectrical impedance method even if the rules are precisely followed.
- As with skinfold calipers (see below) there are different equations used to calculate body fat from your body density. These are usually pre-programmed into the machine.
- The best body fat scales tend to made by Tanita.
Using Skinfold Calipers (Callipers) to Measure Body Fat Skinfold Measurements
Measuring body fat with a set of body fat calipers is the most cost effective way to determine fat levels. But it's important to use them correctly. For instance, either have a professional take the measurements for you or buy a set of Accumeasure calipers (callipers) and follow the measuring instructions. Accumeasure are the only calipers than allow you to test yourself and most studies have shown that they are very accurate.
Using Hydrostatic Weighing to Measure Body Fat
Hydrostatic weighing (underwater weighing) is the most accurate way to calculate body fat - that is, if you can find a hydrostatic weighing tank.
How does hydrostatic weighing calculate body fat? By using Archimedes Principle. Your examiner first calculates your body density by measuring the amount of water you displace when you immerse yourself in water. Then a formula is used to calculate body fat based on your body density. The problem is finding a facility (University, major gym or fitness center) which has a hydrostatic weighing tank!!
Table 1. Body Fat Guidelines from American Council on Exercise
Classification | Women (% Fat) | Men (% Fat) |
Essential Fat | 10-12 percent | 2-4 percent |
Athletes | 14-20 percent | 6-13 percent |
Fitness | 21-24 percent | 14-17 percent |
Acceptable | 25-31 percent | 18-25 percent |
Why Body Fat Measurement is Important
Body fat is an important element in successful weight control. Body fat requires fewer calories than muscle. So the less fat/more muscle we have, the more calories we can eat before gaining weight. Body fat is often expressed as our "Body Fat Percentage" or "Body Fat Percent." Body fat percentage is the amount of body-fat-tissue as a percentage of total body weight. If your total body weight is 160 pounds and you have 32 pounds of fat, your body fat percentage is 20 percent.
Body Fat Calculation and Health
The higher your percentage of fat above average levels, the higher your health risk for weight-related illness, like heart disease, high blood pressure, gallstones, type 2 diabetes, osteoarthritis, and certain cancers. Also, the higher your percentage of fat (and the smaller your percentage of muscle) the less calories you need to maintain your weight and therefore the easier it is to gain weight. This is because muscle is more metabolically active than fat tissue.
