Warm up well and stretch before any activity. Stretch after exercise to keep hot muscles from shortening and cramping.
Drink extra water before and during exercise, or drink an electrolyte replacement drink (such as a sports drink) after exercise, especially during hot or humid weather.
Use the correct movements and positions during activities so that you do not strain your muscles.
Use equipment that is right for your size, strength, and ability.
Try not to overuse your arm doing repeated movements that can cause an injury. In your daily routines or when doing hobbies, think about how often you make repeated arm movements. Try to find other ways of using your arms.
Take lessons to learn how to do sports correctly. Have a trainer or person who is familiar with the sport check your gear to make sure it is right for your level of ability, body size, and body strength.
If you think that something you do at work is causing pain or soreness from overuse, call your human resources department for information on other ways of doing your job or to discuss equipment modifications or other job assignments.
