A rotator cuff injury is an affront to the human desire for control. You follow instructions and protocols to avoid injury and get stronger, but the pain reminds you that you can’t control the trajectory of recovery. Complete rest could be its own disaster. You’re choosing between two bad options.
Not only do you lose control of your body in ways you never imagined—you can’t optimize.
If you’re an exercise buff who struggles with weight and is waiting for affordable versions of GLP-1 drugs, as I am, the compromises forced by a shoulder injury are disconcerting.
My workout on November 29, with kettlebells integrated with shoulder rehab exercises, was not encouraging. My shoulder felt worse afterward. When the Motrin wore off and I woke up at two in the morning, I could tell the training had aggravated it. I began thinking about giving up the Farmer’s Walk with a 45-pound kettlebell in each hand. Perhaps that was too much. My entire training life has been a process of eliminating one exercise after another.
With my shoulder still aggravated from the workout, on November 30 I decided to try my Schwinn Airdyne again, but this time I wouldn’t use my left arm to row the lever. I would rest my hand on it and rely mostly on my legs. The problem was psychological. Using my arms fully, I had burned 600 calories in about 50 minutes—probably more, since the calorie monitor doesn’t calculate body weight, and several forums claim that an hour on an air bike burns around 1,000 calories. Not using my arms would reduce my output, which, in a gamified world, is demoralizing. Still, even without using my arms, the calorie burn would exceed that of walking the neighborhood for an hour while worrying about stray dogs and car fumes.
Exactly a week before—on the day my Airdyne workout was followed by nerve pain shooting down my left arm—I burned 600 calories in 52 minutes, which comes to 11.54 calories per minute. A week later, three days after seeing the doctor, I tried the Airdyne again with a significant disadvantage: I couldn’t row with my left hand. During the session, I protected my shoulder with three strategies. I rested my hand on the lever with no pushing or pulling; I gripped my towel with the left hand while my right arm did the rowing; or I grabbed the towel draped over my neck with both hands. Not surprisingly, I didn’t burn as many calories as the week before. I burned 601 in 57 minutes, which was 10.54 calories per minute. My calorie-burn efficiency was down 9.5 percent.
Despite the significant drop in efficiency, the experiment was half successful: I still reached my goal of 600 calories.
The real test remained: an hour after the workout, how would my shoulder feel?
I showered, ate lunch, did some mild isometrics for my shoulder, and did not experience the shooting nerve pain I had a week earlier, so perhaps I was in the clear with the Airdyne provided I don’t row with my injured side.
I would take this minor victory. The last three months I felt insulted by the difficulty in wrapping a towel around my waist, taking off a sweat-soaked tank top, putting on a belt, closing the driver-side car door, reaching for something in the back of the fridge, and using my left hand to soap my right armpit. Being able to burn 600 calories on the Airdyne was a sweet morsel of consolation.
In this war with a rotator cuff injury, I was willing to take whatever tiny victories I could get.
A small expression of gratitude might help my morose disposition and the self-pity that I had indulged in over the last three months. If I ever were to write and publish a book on my ordeal, I would probably title it Shoulder, Interrupted: How a Torn Rotator Cuff Tried to Break Me.
