Although losing weight through exercise is slower than by calorie restriction, it is more effective. An excellent form of exercise for improved health is jogging. It is simple, required no special skills, and can be enjoyed at any age. It is convenient and involves a minimum of time each week. From a physiological standpoint, it is an excellent form of exercise as it puts a moderate amount of stress on the cardiovascular and respiratory systems.

If you were never an athlete, you will develop your own natural instinct for your personal exercise program. However, anyone over forty years of age should consult his or her medical doctor before starting an exercise program.

The most important factor in the use of exercise to help control body fat is to concentrate on the distance you travel, not how fast you go. The benefits from jogging do not come from speed but from distance. The more you jog, the more muscle imbalances can occur.

Daily exercise for stretching and strengthening of the muscles is very important in your jogging program. The calf, hamstring (back of the leg and thigh), and lower back muscles can become contracted and shortened, as well as tight and inflexible. Therefore, it is extremely important to stretch these muscles. Also, the shin, quadriceps (front of the thigh), and belly muscles can become weakened. It is therefore important to strengthen these muscles.
