J.K. Simmons, the Oscar-winning actor famous for playing intense roles in films such as Whiplash and the first Spider-Man franchise, shows no sign of slowing down at the tender age of 61. He's currently training for his role as Commissioner Gordon in the upcoming Justice League movie, and as some recent gym shots prove, this version of the character will be jacked as all hell. The pictures were shared by Simmons' trainer, actor and former Marine Aaron Williamson. Here are the two workout buds in their civvies:

But underneath that fancy suit, Simmons has transformed into a terrifying killing machine version of Santa Claus. Williamson posted some pics of Simmons working out to prove it:

Every time we train together I forget he's 61 years old. So much respect for this guy. #JKSimmons #OldManCranking

Holy crap! Look at those arms! In this movie, is Commissioner Gordon also Batman? And the beefcake doesn't end there:

Saturday morning, 61 years old & making the young generation jealous. This is what dedication looks like. #JKSimmons
