Stretching: Is It Necessary?

When you start a new exercise program, the muscles you use will respond by getting stronger and stronger muscles tend to shorten or become tighter. Stretching exercises help to maintain and improve your flexibility, and prevent tightness. Also it feels good to stretch your muscles after exercising.

If you stretch, it is important to stretch AFTER you exercise, when your body is already warmed up. Stretching a warm muscle is easier than stretching a cold muscle, and stretching a cold muscle can cause an injury. Stretching too vigorously can also cause injury. Stretch just until you feel a mild pull, but not pain, and hold the stretch for 20 to 30 seconds.
