Good exercise is very important for your health. Fitness experts agree that physical activity is fundamental to fat loss and sustained weight control. Studies suggest that the difference between overweight and normal weight is not solely a product of caloric intake. It is also a result of physical activity levels. Sedentary lifestyle is a prime cause of chronic obesity. Besides its role in weight control, regular exercise promotes numerous health benefits and is a significant factor in improving your overall health and fitness levels. Many health problems that we think of as a part of die aging process - such as lower back pain and heart disease - may actually be related to lack of activity. That's why staying active helps people stay healthy as they get older. People who incorporate exercise to their daily routine tend to feel better and stay independent longer. The key is varying activities to strengthen the heart and lungs and to keep muscles flexible and strong. Here are some tips to get you started. But you must, of course, check with your doctor before undertaking any new program.

Children Excercise
People often picture children playing games, running around a park or bicycling to friend's houses. Yet, the reality is that many children don't get enough physical activity. Why? One understandable reason is because many parents are afraid to let their kids outside alone. Another reason is that parents allow their children to watch television or play computer games for long periods of time.
If children aren't given opportunities to be physically active, they will become lazy and lethargic. Teaching them the importance of exercise, on the other hand, will give them a valuable tool for managing their health now and in the future.

Elderly Exercise
If you are over age 65, you know some of the natural effects of aging. Here's a rundown of just a few of the many changes you can expect to happen with greater likelihood after each birthday: - higher blood pressure
- increased body fat
- progressive bone and muscle loss
- less elasticity in connective tissue
- thinning cartilage in knees and elbows
- osteoporosis
- slowed reflexes
- lowered glucose tolerance
- less elasticity in major blood vessels
- diminished lung capacity
Sounds discouraging, but take heart! Exercise can go a long way towards slowing and even reversing the effects of aging.

Teenagers Exercise
Exercise is not only safe and acceptable for teen-agers, it is also integral to gaining health benefits that can last a lifetime. Problems that can arise from exercise are more commonly related to environmental stresses such as dehydration and heat-related illnesses.

Women Excercise

Kegel Exercises
Kegel exercises are simple, easy-to-do workout schedules to strengthen the muscles of the pelvic floor to improve vaginal, urinary and rectal control. The two sets of muscles groups that surround the vagina, urethra and rectum constitute the pelvic floor. They hold the pelvic organs, uterus and bladder in place. One of the muscles is the pubococcygeal, or PC, muscle. It is a thick, U-shaped band that is attached to the outside walls of the vagina and passes behind the rectum. The PC muscle runs from the pubic bone at the front of the pelvis to the coccyx, or tail bone, at the back. It is this muscle that is strengthened during Kegel exercises.

Reasons for weakening of the muscle
The most common reason for the PC muscle to weaken in childbirth. Other factors are: aging, menopausal loss of estrogen, chronic abdominal pressure due to lung disease or heavy lifting, connective tissue disease and nerve damage due to injury.
When the PC muscle weakens, a woman can develop urinary and stool incontinency, inability to control bladder or bowel. A weakened PC muscle can also lead to decreased sexual pleasure, poor muscle control during childbirth, or in extreme conditions genital prolapse, where the bladder, rectum or uterus moves into the vagina.
Kegel exercises improve these conditions if they have been caused because of a weak PC muscle. But there could be several other factors involved in bringing out the above abnormalities. They range from emotional disorder, infection, inflammation to injury. These exercises also help women suffering from urinary incontinence, especially the urge incontinence in which a person is unable to hold back the strong urge to urinate.
