Warm up. Begin your exercise with a five minute warm-up period. A slow gentle warm-up is more effective than only stretching for preventing injury to your muscles. Walking and riding a bike can be gentle exercise warm-ups.
If it hurts, stop. Don't push through pain. You might be doing more damage than good. Pain is a signal that you are placing an excessive amount of stress on your body. If it doesn't feel right, stop. Also, avoid exercise when you are sick or have any body aches.
