Currently, in his mid-sixties, JK Simmons has a body that could make even the young generation jealous, as Simmons himself once jokingly exclaimed.
But the Justice League actor didn’t get in such incredible shape alone. His famous personal trainer designed two workout routines that Simmons follows religiously.
We’ve spent hours examining Simmons’ interviews and social profiles to find out what his routine and diet look like. Here’s what we found.
J.K. Simmons Stats
- Born: January 9, 1955
- Height: 5’ 11’’
- Weight: 148 lbs
The world was shocked when Simmons’ personal trainer Aaron Williamson shared a photo of the then 61-year-old’s insane biceps.
Many suspected that he got ripped for his role as Commissioner Gordon in Justice League. Not so, explained JK Simmons :
“This is all coincidental. After the second and final time that I got hugely fat in my life and when I lost that weight six or seven years ago, I pretty much decided that I was going to stay in decent shape for the rest of my life.”

He had a lot of help from Williamson, who also trains other stars like Dwayne Johnson and Zac Efron.

JK Simmons Workout Principles
JK Simmons’s workout routine consists of high reps because it follows the principles of Cumulative Blood Volume Training (CBVT).
CBVT is based on the idea that you should pump as much blood as possible to the muscle you’re training to increase its size.
That’s why Simmons’ workouts include superset exercises, which should be done with little to no rest between sets.

JK Simmons’ Diet Plan
JK Simmons sticks to a healthy diet but allows himself to have a cheat meal to stay motivated.
He also tries to eat every three hours to avoid giving in to his cravings if he gets hungry.
Surprisingly, his trainer said that Simmons doesn’t have a detailed meal plan .
Still, Williamson gave Simmons some general guidelines that you can follow, too:
- Breakfast: Eggs and oatmeal
- Snack: A protein shake
- Lunch: Some lean meat (e.g., chicken breast, beef, veal, pork with the fat trimmed off)
- Snack: A protein shake, one square of dark chocolate
- Dinner: Lean meat, low-carb vegetables (e.g., broccoli, spinach, zucchini, iceberg lettuce, asparagus)

His main principle, though, is to eat foods he likes in moderation. He believes that staying on track is easier when you’re not too hard on yourself.
What Supplements Does He Take?
Simmons takes three types of supplements that help him stay shredded and healthy:
- Whey protein: Whey helps Simmons increase and maintain his muscle mass. It also accelerates metabolism, so Simmons can enjoy a few more squares of his favorite dark chocolate without worry .
- Omega-3: Omega-3 keeps Simmons’ heart healthy and reduces the risk of cardiovascular problems .
- Multivitamins: Multivitamins are beneficial for overall health, from the immune system to the brain .
Many suspected that Simmons was taking anabolic steroids, but these are probably just rumors since the American actor is very health-conscious.
