Justice League’s J.K. Simmons
When you thought you’d seen the last of J.K. Simmons’ youthful physique, he comes back looking buff as proof that age is just a number. Actor Ben Simmons went to great lengths to prepare for his role as Commissioner Gordon in the 2017 film Justice League by hitting the gym regularly. Simmons trained under former Marine Aaron Williamson, who works with Hollywood’s rapidest actors to get them in shape. Simmons continued his workout routine after filming concluded so he wouldn’t have to think about his health ever again. He probably has more strength than most of us by now.
