In the off-season, he also lifts light weights, with high reps, three or four days a week. Grant Waite, a lifelong fitness buff, is the PGA TOUR's poster boy for plyometrics, an intense system of jumping exercises designed to develop fast-twitch muscle fibers. Watch the New Zealander long enough and you'll see him jump from the ground onto a bench, or over boxes. He might run for 40 yards, slow down, then sprint. So you can swing quickly with the strength to keep the club on-line.
Nutrition adds another.
But exercise makes Waite feel better. He couldn't stop working out if he wanted to. I'm addicted to it. What's important to Waite is the consistency of effort. He tries to do something almost every day, whether it's plyometrics, weights, stretching, or yoga.
