Celebrity Transformation: The Workouts That Got J.K. Simmons Jacked

Two routines, straight from the actor's trainer, to help you trim fat, bulk up, and hone a leaner physique.

In case you're not privy on all things pop culture, J.K. Simmons seriously, seriously underwent a shred in order to play Commissioner Gordon in Justice League (in theaters November 17, 2017) that could rival most of his costars. Check out more photos of Simmons here.

 

Aside from a tremendous amount of dedication to his regimen, Simmons credits part of his success to his trainer Aaron Williamson. An ex-Marine, Williamson's been providing elite-level training—morphing Hollywood A-listers into bona fide muscleheads like he's cranking out action figures on an assembly line—to the likes of Zac Efron, Dwayne Johnson, Jamie Foxx, and Jai Courtney. He first got his hands on Simmons in 2015 to help him shape up for Terminator Genisys.

At first, Simmons wanted to escape the doldrums of the film's set, which was based in Louisiana, but after shooting wrapped Simmons felt he was ready for a full-body change.

"He wanted to get into the best shape he had ever been in," Williamson says, adding, "J.K.'s goal was to adopt a healthy lifestyle and never have to worry again about health issues." 

Try your hand at two sample workouts Williamson created for Simmons (below). Don't underestimate their intensity. While Simmons is 61-years-old, he's operating like a madman—a madman that can maybe even outlift you.
