Contrary to popular belief, J.J. Watt is human.

The 6-foot-5, 288 pound Houston Texans defensive end has demonstrated his freakish athleticism by jumping over boxes and people:

But there was one challenge that Watt couldn't conquer, and he wasn't embarrassed to let the world know. Watt, who is training this offseason in a secluded cabin in the woods of Wisconsin, posted these photos to his Instagram account:

Watt landed a 59.5 inch jump in the video above but apparently 61 inches was too much for him. That poor spotter can relate to the numerous NFL quarterbacks who have also been taken down by Watt.

The 2014 NFL Defensive Player of the Year, Watt has made a name for himself by dominating in all aspects of the sport. In 2014 he tallied 20.5 sacks and forced four fumbles. He even lined up as a tight end and caught three touchdown passes.

He's also a skilled hockey player who wears No. 99 as a tribute to Wayne Gretzky.
