Time: 30 Seconds
While in pushup position, explosively bring one knee up to your chest. Then drive it straight back while you bring the other up. Do as many reps as you can in 30 seconds. Then it’s your buddy’s turn.

In this special-edition of The Fit 5, two mixed martial artists, Johny Hendricks and Jamie Varner give us an inside look into living life as a pro fighter.
