New England Patriots superstar tight end Rob Gronkowski is a tough nut to crack. He’s one half party machine, one half exercise fanatic. 

The Rob Gronkowski workout allows him to be the superior athlete Tom Brady can relies on. You can see Gronk showing off his thrusts on a moving boat below. 

Could this also double as Gronk’s bedroom workout? I’m guessing everything Gronk does in the gym has a purpose, because we know there’s only one thing Gronk loves more than football, and that’s the ladies. 

What woman wouldn’t want to be on the other end?
