Talk about having some old man strength.

Pittsburgh Steelers linebacker James Harrison might be 38 years old, but he remains one of the hardest-hitting players in the NFL—and one of the strongest.

Harrison has never met a lift he couldn’t conquer, a machine he couldn’t dominate, or a workout he couldn’t crush. The dude is shredded and he’s showing no signs of slowing down, even though he’s nearly 40. We’ve shown you Harrison crushing a 425-pound lift and a crazy “super band” bench press, but that’s only a small sample of what the linebacker can do in the gym.

Those lifts and workouts helped Harrison win two Super Bowl titles, an NFL Defensive Player of the Year award, and earn two All-Pro team selections during his career—plus, he pulled off one of the most legendary plays in NFL playoff history when he returned a Kurt Warner interception 100-yards for a touchdown:

Here are 30 of his best workout moments:
