I feel silly for having this problem with my right pec, so I figured I may as well explain it so people don’t think I’m just being a wuss on bench presses.
Well, I guess I am a wuss with the kinds of weight I have trouble moving, but I digress. . .
In the shoulder girdle there are four muscles which make up the rotator cuff. They are supraspinatus, infraspinatus, subscapularis, and teres minor. Their job is to keep the humerus depressed in the glenoid fossa (a little depression on the side of the scapula) while the larger muscles (pecs, lats, delts, etc. . .) do their thang. In a sense, the larger muscles have a tendency to pull the humerus out of that little socket (this is a simple way to look at it).
When one of those little rotator cuff muscles doesn’t do its job, another muscle or couple muscles have to kick into high gear to make up for things.
In my case, subscapularis wasn’t doing its job. It is on the front of the scapula. It works with pec major in some humeral actions, so, when subscapularis on my right side wasn’t doing its job, my pec major was like “ZOMG, wtf bro, my turn.” Mr. Pec Major had too much work for one muscle to fulfill, and eventually encountered a few strains. 4 total at this point, to be exact.
So, subscapularis didn’t do its job. Pec major had to start working harder. Teres minor and infraspinatus on the back of my shoulder girdle had to start working harder to pull my humerus into that socket as well. Pec major, infraspinatus, and teres minor accumulated hella scar tissue and some flexibility deficits.
So, how do I fix this?
- For one set at the beginning and one set at the end of every upper body day, do prone internal rotations
-This will double as activation work and hypertrophy work - Between sets on my main exercises, do SMR on infraspinatus and teres minor to knock down that scar tissue.
- Foam rolla the hell out of pec major.
- Sleeper stretches to keep adequate length and infraspinatus and teres minor.
Alrighty. . .
On top of that, I’m going to keep working on balancing my triceps strength out. My right arm is still 1/2 an inch smaller! Nothing to stress about, but the size difference is reflected in strength performance, so I’ll fix that.
Now that I’ve shaken my nerdiness off, IT’S TIME TO PLAY PAINTBALL.
PISTOL, HERE I COME!
YEAHHHHHHHHHHHH BUDDDAAAAAAYYYY!
