Asking your health care provider if you have any exercise limitations is the first place to start. If yes, ask what specific types of exercise you can and cannot do. The most beneficial exercises will depend on how long ago your injury took place; how completely your shoulder has healed; and your current level of shoulder function. Doing too much, too soon — or exercises that are risky, given the nature of your injury — puts you at risk of sitting on the sidelines with another injury.
Ideally, you should undergo a functional assessment with a registered physical therapist or a certified personal trainer to identify any lingering range-of-motion or stability issues in your shoulders.
Generally, starting with exercises that improve shoulder flexibility and stability is a good idea. Exercises like shoulder packing, supine snow angels, supine rotator cuffs, and supine shoulder flexion will help enhance shoulder function.
If you’ve been cleared to exercise with no limitations and your shoulder function is normal, you can start some strengthening exercises. Examples include dumbbell lateral raise, dumbbell front raise, and bent-knee push-ups.
