Pittsburgh Steelers linebacker James Harrison is at it again. The 37-year-old 13-year NFL veteran is pushing enough big weight to shock the world. Some say the Steelers linebacker is too old, or past his prime; but it seems like Harrison is taking no time off this summer.
The All-Pro is definitely performing some "do not try this at home"-type exercises. Harrison posted a couple workouts on his Instagram that will make you double check his age.
Whether running with a weighted vest, bench pressing over 500 pounds or playing volleyball with a huge med ball—leave these exercises to Harrison.
Check out all his insane workout posts below:
