There's no easing back into training for Fitzgerald. "It's right into high-intensity workouts," he says. "They're brutal. Not fun at all. But totally necessary." To keep it this way, Bill Welle, his trainer since high school, likes to include a competitive element.

"It's always easier to push when someone is trying to beat you," Welle says.

"Competition is what makes you great," agrees Fitzgerald. "Games are competitive, so I like to keep it competitive in practice and every day in training.  It gets me mentally and physically ready for game day."
