Before you exercise you need to stretch your muscles. You've probably seen joggers stretching. It looks as though they’re leaning against a tree or a wall, trying to push it over. That kind of stretching (and there are various different stretching exercises) is very important to prevent injury.

Stretch gently now, it doesn't need to hurt to be effective. Dr. Richard H. Dominguez, a sports medicine orthopedist in Illinois, has gotten a certain amount of notoriety because of his outspoken criticism of excessive stretching in runners.

You can do more harm than good if you stretch too much. Some people are naturally and easily more flexible than others.
