Today in viral content: J.K. Simmons is getting super jacked for his role in Justice League.

Posted five days ago by Aaron Williamson, a former Marine and personal trainer to such stars as Dwayne “The Rock” Johnson and Zac Efron, the picture shows Simmons lifting a pair of dumbbells in the gym.

“Every time we train together I forget he’s 61 years old. So much respect for this guy,” Williamson wrote on Instagram, using the hashtags #JKSimmons and #OldManCranking.

Simmons is set to play Commissioner Gordon in Justice League, which is filming now and out on Nov. 17, 2017. Check out photos of Simmons’ ridiculous guns below.
