The following exercises are the core of Sorenstam’s program. Consult your doctor before beginning any weightlifting program.

Squats: Fusser says that although squats work the legs the hardest, they also involve the abdomen, sides, and back.

Sorenstam can squat up to 300 pounds and usually does three sets of eight repetitions.

Pull-ups: Most women — and many men — can’t do these. That’s one of the reasons Fusser chose them for Sorenstam: There’s a psychological boost to mastering a very difficult exercise. Plus, they’re great for overall upper-body strength. Sorenstam does three sets of eight with a 25-pound weight.

Wood chop: This exercise targets inner abdominal muscles that are integral to rotational power. It also helps the same muscle groups used in the golf swing to work in sync.
