I did that. I waited two and a half years. They have healed but need exercise low and slow to get back. It is my bow arm shoulder I injured. This exercise also eliminated tennis elbow in my drawing elbow. I always thought I used my shoulder and back muscles, until I tried the Formaster. I was drawing with my hand wrist, forearm and bicep. Once I exercised with the formaster it forced me to use shoulder and back muscles, which in turn enables you to keep a relaxed hand, forearm and bicep. Using your shoulder and back muscle in and of itself enabled me to draw heavier weight.
I actually used a crossbow for a year. Now that I can shoot and hold my bow up I am now building back my strength again. This exercise is great also to maintain and gain strength. The original info and pictures were for Olympic archers for exercise.
In every sport participants not only practice but exercise for strength and stamina.
I can’t think of a reason to prevent me from getting more bow strong for shooting. I have a moderate goal of reaching 50#. I now am shooting 44# comfortably.
shooting practice should just be practice not exercise, in my opinion.
