Found this quite popular shoulder prehab routine on his blog. http://idoportal.blogspot.se/2009/07...-training.html
Something I´ve been thinking about, is if it wouldnt be more "appropriate" to do the routine facing the other direction?
If I´m not mistaken alot of shoulder injuries are due to the anterior shoulder being a lot stronger.
So facing the other way would utilize the posterior deltoid instead of giving the anterior part even more work?
