On the one hand, I hate discovering my weaknesses because I really don't want to have any. On the other hand, when I find them I can work to eliminate them. I have the shins under control, and am working actively on my back so I can hopefully keep it from going out every other year. Up next? My rotator cuff. I haven't torn it or anything, but I have nagging soreness that is starting to get in the way of my pushups, pullups, and will certainly be an obstacle in some of the more advanced skills I'd like to tackle. So here's what I've learned:
From the March 2002 issue of Men's Fitness, Big-League Shoulder Protection by Roy M. Wallack:
The most common injuries in sports are to the shoulder. The overhead (military) press and deep dips both put huge amounts of stress on the shoulder (see tip No. 2). So does throwing a baseball, swimming, rowing, or swinging a racquet--anything that repeatedly puts your arm over your head, or raises it out to the side or pulls it in, exerting lots of extra force on the shoulder joint.
The problem is that the shoulder isn't as strong as it looks. The humerus (upper-arm bone) has a large range of motion only because it dangles precariously off the edge of the body. The humeral head is pulled sideways against the socket of the scapula (the shoulder blade) by a series of four small upper-back muscles collectively called the rotator cuff. These muscles are the foundation, the unsung heroes, the glue that holds the shoulder joint together. When they ate weak or overpowered, the humerus gets out of line and undue stress is placed on tendons and ligaments. And you feel pain.
It's easy to strengthen the rotator cuff muscles—if you can remember to work them, that is. Since these so-called "precision" muscles (which precisely center the humeral head) are invisible from the outside, they're easy to overlook. Big mistake.
We love to build up the glamorous "outside" muscles, the triceps, biceps, delts, lats. "Ironically," says Jobe, "the stronger these get relative to the rotator cuff, the more at risk you are of pulling the humerus out of its tenuous socket, injuring the AC joint (the juncture of the clavicle and the acromion, the front of the shoulder blade) and even tearing some tendons." The latter is the dreaded "torn" rotator cuff. Bottom line: Ignore the rotator cuff at your own peril.
That article also includes a laundry list of dangerous exercises, which includes pushups! Basically, it includes anything that puts your elbow behind your body. Sigh. I am unwilling, however, to give up dips and so thoroughly compromise the range-of-motion on my pushups. So hopefully strengthening my poor neglected rotator cuff muscles will do the trick. The article above has the exercise illustrations stripped, so here are some from The American Academy of Family Physicians and some more from Body Results.
Encouragingly, this happens not only to people like me, who are climbing the fitness ladder, but also to guys like Matt Furey, who stand on a pretty high rung:
What I have to tell you is something you can etch in stone right now. And that is ... There are muscles all over your body that cannot be adequately trained with weights or with body weight calisthenics.
You may wonder, how do I know this? Good question. I'll answer by telling you about the shoulder injury I sustained from a combination of:
a. wrestling
b. the gymnastic rings
c. throwing whip-like backhands
The injury sort of crept up on me. Thinking it was just a nagging annoyance, I kept on. Then, in December of 1999, a day after giving a seminar in Philadelphia, I could barely lift my right arm. In fact, the only way I COULD move it was by grabbing beneath the elbow with my left hand and pushing it where I wanted it to go.
I gave it a rest for a week and it felt a bit better, and so, even though I couldn't use the arm too well, I kept on wrestling, thinking I would eventually get over it. A month later, I stopped wrestling for two months to let it heal. Sure, it got better during that time - but it was still weak.
Whenever I thought I was much better, I would try some Hindu pushups. It would feel okay for awhile, but then, after a couple days, I was back to agony again. Through a combination of deep tissue massage and herbs, the shoulder would feel much better - but because the pain came back when I trained, I feared that my Hindu pushup days were over.
He then goes on to sing the praises of the Lifeline Chest Expander. I think I'm going to stick with the aforementioned exercises and stretches for now, but he does a quite a job of making it sound like the greatest thing since sliced bread.
