Can I lift weights while doing the Shoulder Fix?

It's better to just do the Shoulder Fix program for at least the first two phases without other weight-lifting. The Shoulder Fix does include resistance training, but it will not be intense.

Taking time off intense weight lifting will help you get clarity on your shoulder issues and that'll help you also adjust your weight lifting in the future so you can stay impingement free for the long run.

Phase 3 of the program does introduce weight-lifting / resistance training so that'll be a good time to pay attention as you transition into lifting weights again.

Remember if you cannot maintain good range of motion and good form without pain, you may not be READY to lift heavy!
