Weight: 267 pounds
Growing up in Ireland, Sheamus started lifting weights when he was 18 years old. He also was big into rugby, which gave him superstrong legs. These days he does a workout designed by WWE's strength and conditioning consultant, Rob MacIntyre. It's called the Celtic Warrior Workout (for obvious reasons), and the strength routine goes something like this: Train five times a week, splitting days between lower body and upper body, set weights as heavy as you can, and try not to rest too much. He wraps it up with some stretching and flexibility work to help his career last as long as possible (Sheamus is now 38-years-old). Although he doesn't count calories, Sheamus tries to keep his diet clean. He downs six meals a day that tend to consist of protein shakes, chicken, egg whites, and porridge. He does have some wiggle room though, and is a self-proclaimed huge fan of Ben & Jerry's ice cream or McDonald's while he's on the road.
Room for Improvement: "While the Ben & Jerry's probably helps him get to his calorie goal each day, his diet is remarkably lacking in plant foods, except for the porridge," says Kleiner. Her advice: Boost the whole grains, fruit, and veggie intake.
