Champions aren't born, they're forged through hard work, practice and dedication. UFC Fighters Paige VanZant, Anthony Pettis, Chad Mendes and Dominick Cruz are working out in an empty warehouse. In place of punching bags and weights are Toyo tires strung up for the fighters to practice their striking. Some fighters even use the tires as weights for their dips and pull-ups. A Newton's cradle composed of Toyo tires is even set up for the fighters to kick.
