Your mind will melt watching this swimmer complete an individual medley in reverse.
Swimming is one of the most grueling activities a human can undertake as evidenced by the hundreds of stories about the abundance of food stars like Michael Phelps and Ryan Lochte eat every day just to keep their bodies going.

Eirik Ravnan posted the full video to his Facebook page, and in it says he began the odd warmup as “agility training.” It probably serves the dual purpose of psyching out his competitors.
