This video has been floating around on Twitter for a few days, but if you haven't seen it, you probably want to take a look.
Former Kentucky defensive back Winston Guy registered an (alleged) 61-inch box jump in this video. That means he started from the ground and jumped on a stack of plates 61 inches up, without any assistance. He barely even got a running start. It's a move that's all about explosive power in the lower body and balance.
