Heres a good tip from pro-staffer I learned when I started bow hunting, before you shoot, make sure youre reaxed, then do some shoulder and elbow excersies, do about 3 minuterotating shrugs with both shoulders, alternate both directions. Then lift your arms straight up and go air swimming. This will work both elbows and shoulders along with most of your upper body muscles do this for 3-5 minutes. Then wait about3-5 minutes before shooting. If you still get some pain,wich im sure you will, do this everyday, not just before you shoot. If It doesnt go away, contact someone in physical threorapy.
