TweetWhat have you done to stop this? Stop doing behind the neck Military Presses and Behind the Neck Lat Pull Downs. Start warming up more and working your rotator cuff. A cycle will aggrevate the problem if you continue to keep doing the same things that bother it.
There is a new Hammer Strength machine for Front Military Presses that takes you just forward enough off your verticle plane to not stress your rotator cuff.
