Designing Your Stretching Program (5)
For the intensity of stretching, you really want to make sure that you're not causing pain while you're stretching. Slight tension and mild discomfort are okay, but pain should never be felt while you're stretching. It's also important that for relaxation purposes, to maintain a relaxed state in your muscle, and in your overall body, that you continue to breathe throughout the stretch and that you're not holding your breath while you're trying to stretch your muscles.
