Hi Deb! I'm glad to hear you are able to do push-ups again! It sure is frustrating not being able to keep up with the moves due to injury.
I think I have shoulder bursitis. I had surgery over 15 years ago and recently had one round of physical therapy for the pain. They gave me small, isolated exercises like "external rotation", "external rotation in abduction", "Prone horizontal abduction in neutral and full external rotation 100 degree abduction". They also had me do some rhomboid strengthening. They had me do that before going back to normal exercises.
I decided along with ice, and massage (good idea!), I'll start doing those exercises again.
So, we are about to embark on Insanity Max and I figure I'll just modify all the moves I can't do. Huzzah for recover week!
