The Crossfit-perfect workout move of flipping tires can be a great way to build strength and transform your body . . . but for Kevin Hart, that wasn't challenging enough. For his "rise and grind" workout, the actor decided to forget flipping; instead, he stepped inside the giant tractor tire and lifted it! We know that Hart loves to show off with heavy weight during his workouts, but this takes things to another level.
We're sure Hart's friend Dwayne "The Rock" Johnson would approve of this impressive feat of strength — after all, tires of this size typically weigh between 400 and 600 pounds. Wow! Hey Kevin, can we get some help changing this flat?
