If there's one thing the Watt brothers understand, it's training harder than everyone else—especially the competition. All three (J.J., Derek, and T.J.) play in the NFL. They're the definition of a football family, and they've been dominating the league since J.J. was selected by the Houston Texans in the first round of the 2011 NFL Draft.

Neither J.J. nor his brothers have slowed down since. Now they've got a new addition to their fitness regimen to help them stay at the top of their game. Meet the Hydrorush, Reebok's newest—and arguably toughest —training shoe yet.

"[It's the] perfect shoe to train in because I can do any workout—from speed drills to lifting and agility—all in one shoe," says Derek Watt, a Reebok brand ambassador and fullback for the L.A. Chargers. And at less than $100 (it retails on reebok.com for just $80), the Hydrorush is a steal, considering its durability and high-tech components, like versatile traction (you won't slip, no matter the terrain on which you're training) and maximum foot security.

Here's everything you need to know about the Reebok Hydrorush. For more on how the Watt brothers train on and off the field, check out the video below:
