Found this quite popular shoulder prehab routine on his blog.

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?
