Arnold Schwarzenegger is the ultimate motivator and fitness icon. Meet his latest client, revered NFL pass rusher J.J. Watt.The two-time Defensive Player of the Year has been busy this offseason working on his amazing box jump technique, which has undoubtedly been preceded by his workman-like effort on the squat rack. Schwarzenegger challenged his new colleague in fitness to pump out 50 squats; albeit in some tight jeans. When the gauntlet was thrown down to Watt, he responded like a champ.

Watt has enjoyed his off-season, most notably when he worked security at a recent Zac Brown Band performance and flattened an unruly fan. He has even received a generous invitation from Arnold to be the T-100 in the next episode of the Terminator franchise.

We salute you, #99!
