The biggest thing you can do is assure that your draw form is spot on to have maximum transfer to back as much as possible. I just had rt shoulder surgery again April 1st. 2nd in 2 years. Seems I had a calcium 1" dia deposit that sawed thru my rotator. So not repairable but in PT building strength. 5 weeks post surgery and have full rotation. Just starting low weight 20 lb PT. I just ordered new 50-60 limbs for my Hoyt XXL. I am certain I will be able to draw low weight to protect life of shoulder going forward. Have xbow but yuck! Added pic of the calcium deposit. Should have been removed but wasn't.
. If you are not certain on draw form, find someone who can show you, watch and coach you up. It will make ALL the difference in the world for being able to draw safely.
