3. Seth Rollins
Weight: 217 pounds
A few years ago, Rollins discovered CrossFit and has never looked back. "CrossFit takes all the elements of fitness that I want to focus on and mashes them into an intense workout," Rollins told Men's Journal. "That helps me stay on track and have fun at the gym too, which is a big part of wanting to go in there and putting in the work." It's also useful in the ring. "The intensity level is constant and high, and there's variables you can't foresee in our in-ring action," he says. "And having to work at a high level while you're under duress is something we're accustomed to, so training like that really helps us." As much as Rollins loves the workouts, he hasn't completely adopted a Paleo diet, popular among the CrossFit crowd. While he tries to stick to high-protein, high-fat, low-carb, and low-sugar food, he sometimes has to make do with a Wendy's Baconator (sans bun) on his way through an airport.
Room for Improvement: "An athlete needs carbohydrates to accomplish high intensity training and to perform with the power and speed a wrestler needs," says Kleiner. "Avoiding added sugar is a healthy choice, but he needs to include grains, beans, vegetables, and fruit in his diet to sustain hard work over a long time."
