My Favorite Rotator Cuff Myth
This is a common belief :
If you fix the rotator cuff, you fix the shoulder
Here’s why it’s not true
What is the rotator cuff?
It’s the muscles on the shoulder blade that wrap around the humeral head. You can nerd out on that here
I could describe cuff function in simple terms with words like
shoulder stability
muscle actions
Or be more esoteric and say things like “centration” and “line of pull”
but I won’t because none of it matters. You know why?
Because they are SMALL muscles
The one that’s the most often torn and repaired, the supraspinatus
is THE smallest
So I don’t care about the cuff’s “muscle actions” to the shoulder since as you demand MORE from your shoulders, the other muscles
pecs
lats
shoulders
Become MORE important.
Things that matter more
FULL shoulder ROM
Full BIG muscle mobility (pec, lat, bicep to some extent, even tricep)
Good exercise technique
Good exercise program
