Former American Ninja Warrior contestant Warren James Li is taking burpees to the next level - and that's not just a quote from his Instagram caption. Behold.
Apparently when you get to a certain level of fitness, burpees are not enough. If you're at the American Ninja Warrior competing level like Li, you must catapult yourself toward space, using a basketball hoop as leverage, do some calisthenics, crazy push-up tricks, and then do it again.
Li says #ChallengeYourself in his caption, but honestly, we feel challenged just watching that video. Holy crap.
