James Harrison is known for his insane workouts, consistently posting videos on Instagram of him lifting heavy things in new and creative ways. You can find him wearing the same grey Pittsburgh Steelers sweater, covered in what appears to be a plethora of sweat, taking part in a workout.

Before anything about this specific workout is touched on, we would like to start out by reminding everyone that James Harrison is 39 years old.

It’s hard to believe someone would think of using a medicine ball to play a game of Volleyball, but then again, this is a pretty intense man we’re talking about here.  

The 39-year-old totaled 39 tackles, 14 assists, and 5 sacks in 7 games started. After 14 seasons in the NFL, the half man, half machine that calls himself a linebacker shows no signs of slowing down.
