Skeletal muscle mass—still getting stronger, despite dermatomyositis

Despite having dermatomyositis—my condition in which my immune system is attacking my skin and muscles—I’m still getting stronger. My skeletal muscle mass and body fat mass is better than I expected.

Despite battling dermatomyositis, my body fat mass is right where it should be and my skeletal muscle mass is above average. I’m even stronger than I was a couple months ago.

Saturday, my girlfriend and I went to the Nutrishop in Tempe to stock up on workout supplements and enter ourselves into a competition. The $1000 shopping spree goes to he or she who loses the most weight and grows their skeletal muscle.

I don’t need to lose weight, but I am trying to gain muscle. I already work out five days a week, so why not enter? Even if I don’t win, it costs me nothing. Plus, these creatine and stimulant supplements essential for fighting my disease are expensive.

Much to my surprise, my numbers came back very good. My body fat mass is right where it should be and my skeletal muscle mass is above average. In short, I’m stronger and healthier than I sometimes feel.

Gym Results: Evidence of Dermatomyositis

A few weeks ago, my gym results were the only way I knew dermatomyositis caused my muscles to progressively weaken. Between February and late June, I lost almost half my upper body strength.

Muscle Loss of Strength (Percent)
Triceps 40.9
Biceps 45.8
Deltoids 33.3
Trapezius 45.8
Pectorals 52

My Gym Results

I have never been the strongest guy in any room. Standing 6’5”, built more like a wide receiver than a linebacker, most of my strength is in my legs. Before tearing and repairing my meniscus, I could leg press over 700 pounds.

But with a high metabolism and a sprinter’s frame, upper body strength has never been natural for me. I worked my ass off in the gym four to five days a week during my twenties just to have a body that halfway looked and felt like a man’s.

My peak strength came in summer 2016, aged 31. Since then, between work, age, and inconsistency, my strength dropped a bit. Since February, it fell off a cliff. By June, one push-up seemed impossible.

Getting Stronger Every Day

With numbers like these, I have to be careful not to give up, to compare myself to the gym rats and roid ragers. I can only be who I can be.

When I look at stronger men at the gym, I remind myself my immune system is attacking my muscles, theirs is not. Worse, most anti-autoimmune drugs also induce muscle weakness. While they do reduce muscle inflammation, their benefits are almost immediately canceled out.

But the people at my gym barely notice. Some are weaker than me. I doubt those stronger care. In fact, two have even helped spot me while I embarrass myself at the bench press. They even offered sympathy for my disease.

Since June, I’ve made progress. I workout four to five days a week. I eat a high-protein, creatine-supplemented diet. I’ve gained strength in several muscle groups. Compared to my numbers in the right column above, I can do more reps with more weight.

Activity Reps / Weight (lbs.) Reps / Weight (lbs.)
Bench Press 10 / 65 10 / 75
Bicep Curls 10 / 65 10 / 85
Lateral Deltoid Raises 8 / 20 (10 each arm) 12 / 20 (10 each arm)
One-Arm Dumbbell Row 10 / 45 12 / 55
Seated Cable Row 10 / 60 10 / 90
Push-ups 1 / 215 5 / 215

Those five push-ups are sloppy, to say the least, but for now, it’s progress.
