 J. K. Simmons is getting totally jacked.

The swole patrol sirens sounded this week when the Whiplash Oscar-winner flaunted his muscular new physique on Instagram. 

The 61-year-old is getting into serious shape for his role as Commissioner Gordon in the upcoming Justice League movie. It's just a shame he didn't have these guns back when he was playing an evil convict on HBO's Oz.

Simmons has been pumping iron with celebrity trainer Aaron Williamson, a retired Marine who has an enviable record of whipping actors into shape.

Williamson notably made Zac Efron believable as a jacked Jarhead for The Lucky One, and he even trains The Rock.

If there's ever a Whiplash sequel, Miles Teller doesn’t stand a chance.
