Luke Kuechly does tennis ball circuit workout (VIDEO)

Luke Kuechly likely has a wide array of different workouts, but this one definitely catches the eye. The video below comes from NFL.com, as Kuechly runs through the tennis ball circuit drill with Ignition, a training facility which is based out of Cincinnati.

Whatever Kuechly is doing seems to be working well, as he's quickly become one of the best linebackers in the entire NFL. With that said, I'm guessing he probably lifts a few weights every once in a while also.
