When he was younger, Fitzgerald could do whatever he wanted, but now, at 30, he knows his body recovers slower than it once did. "I want to make all the right moves so that the next day I can work out at the same capacity as the day before," he says. To this end, he takes great pains to make sure he's eating well. As soon as each workout is done, he drinks a protein shake from his sponsor EAS Sport Nutrition. He's also taken cooking classes in an effort to make sure he can properly prepare a highly caloric yet balanced meal from scratch.
