Pittsburgh Steelers linebacker James Harrison has a thing for dressing in gray sweatsuits and performing feats of strength that should probably be impossible for humans – let alone 39-year-old humans.

In Harrison’s latest Instagram workout video, he pushes a sled weighing 1,800 pounds (nearly a literal ton).

That sled weighs more than an entire offensive line.
