7. Titus O'Neil
Weight: 270 pounds
It's no surprise that someone who used to be a defensive lineman for the University of Florida is a solid hunk of muscle who can bench 545 pounds. He gets his high one-rep-maxes by following a four- to six-week cycle lifting low reps with lots of weight on the bar. He's also constantly in the gym, fitting in workouts at all hours to make his schedule work. He keeps his diet a bit of a secret, but he doesn't try to hide his love for barbecue and once took part in a Thanksgiving eating contest on live TV.
Room for Improvement: "He follows a traditional pyramid training program, which is a great way to break plateaus and make gains," says Raul Hurtado, owner of San Francisco Strength & Conditioning. "However, without proper periodization [scheduling your training so that you vary intensity, rest, volume, and other factors, letting you plan exactly when your performance is going to peak], he risks injury. He also doesn't address other components like cardiovascular endurance and flexibility."
