Some
band-resisted exercises would probably be pretty helpful. They are a great way to train. They are helpful with injured parts because they "progressively load" and they also start improving your reactive strength as well as challenging your stamina.
I've had multiple shoulder surgeries and this is one way to help my train without injuring myself.
It's also great for cyclists. Some of the stretches you can do with bands really help with the areas you tighten up from lots of riding (hip flexors, deep hip flexors, and lateral compartment of the hammies).
