If you have shoulder issues of any kind – from shoulder pain, rotator cuff or shoulder mobility issues (including partially frozen shoulders or seriously forward rotated shoulders) then this technique should be at the top of your list for self-help techniques.
If you have breathing or rib issues this could be related as well.
Pec minor is actually somewhat difficult to get into. Pec major and the clavipectoral fascia sit on top of it, and when your arm is resting or hanging at your side you can’t get into it at all. In order to get at this triple headed small muscle and its fascia you’ll need to raise your arm and target a very specific spot for release. (I show you exactly how in the video).
To be clear, what we’re actually going after here is the fascial adhesion that can occur between pec minor and pec major (specifically the , the clavipectoral fascia and possibly coracobrachilais as well.
From the picture to the left you can see how (because of its attachment at the coracoid process of the scapula), if shortened or adhesed, pec minor can pull both the shoulder joint and the scapula into forward rotation, and/or elevate the ribs. Someone who, later in life, has a serious hunch or “wings” showing in the upper back – you can bet they have a very short, tight, adhesed pec minor (in addition to probably a lot of other fascial tightness in the front as well).
If you’re someone who has ribs “go out” a lot, I would instantly suspect ridiculously tight pec minor tissue. This would not be the thing itself that makes a rib go out, it just sets you up and makes it much more likely. This has been true of my clients who play lacrosse, train jiu jitsu or those who have experienced a traumatic fall or impact such as a car accident, falling onto a shoulder or their head while snowboarding etc.
