Warm–Up & Stretching Exercises. Prepare your muscles and joints for activity by warming–up and stretching before you play. A warm–up routine increases blood-flow, raises the body’s temperature and improves balance, flexibility and coordination so you can play at your peak while avoiding injury.
It is very important that you perform the general warm–up before you stretch. It is not a good idea to attempt to stretch before your muscles are warm (something which the general warm–up accomplishes). Warming up can do more than just loosen stiff muscles; when done properly, it can actually improve performance.
