How does Glee's Harry Shum, Jr. keep that amazing body in check? He spices up his workout routines with mini dance breaks, apparently!

Shum posted videos of his shirtless self at the gym on Twitter and Instagram Tuesday, impressing us with his physical prowess and slick dance moves. Any man who can go from an air crunch to a Justin Timberlake-y wiggle in a matter of seconds is a man after our own heart.

Swoon!
