Former Steelers linebacker James Harrison’s Instagram feed is a collection of superhuman feats. Harrison, now 42, posts videos of his ridiculous workouts all the time. He loves working out so much that he once hit the gym directly after his team’s flight back from a road game touched down in Pittsburgh—at 3:45 a.m.
Three years ago, at the age of 39, Harrison put 39 weight plates on a sled—more than 1,800 pounds—a tried to see if he could push it. He could, of course. For his 42nd birthday on Monday, Harrison asked his followers if he should attempt to push 42 plates.
