How to release your pec minor to resolve rotator cuff tendinitis

For patients suffering from rotator cuff tendinitis, the problem is rarely the shoulder joint itself—it’s the position of the shoulder blade, often caused by an overly tight pec minor, which puts excess pressure on the rotator cuff tendons. So if you release the pec minor, you can reposition the shoulder blade, relieving the excess pressure causing tendinitis.

And to do this, all you need is a hard ball. Here’s how. 

Step 1

Place the ball—it can be a TriggerPoint ball or an ordinary lacrosse ball—on your pec minor. 

Step 2

Sandwich the ball between your chest and the wall. Lean in to increase pressure. 

Step 3

Move your arm in multiple directions. To release a different part of the muscle, change the position of the ball on your pec minor. 

Step 4

If you come across a tender spot, spend extra time there--going up and down, and side to side until you fully relax the area. 

Pro Tip

If you find the wall too awkward, try using a yoga block instead.
