16. Dean Ambrose
Weight: 225 pounds
While many Superstars try to be the biggest, strongest guy out there, Ambrose aims to win by outlasting everyone. So he trains with long runs and long bike rides, focusing on stamina. "I'm not going to throw 27 people over the rope at one time, but I am prepared to be pounded on for 60 minutes or so," says Ambrose.
Room for Improvement: "If he were a triathlete, where he would need to do a single controlled movement for a long time, this would be perfect," says Butterworth. "But that's not what wrestling is. He would do a better job of building his VO2 max and stamina with intense bursts of activity, say sprinting for 30 seconds, resting for 30 seconds, and repeating."
