Tiger Woods and Annika Sorenstam improve their game by doing Pilates to reduce strain and their lower back and shoulders.

Learn their secrets with a four-session course sponsored by the Anthony Rabara Pilates Studio of Princeton, which offers four one-hour sessions starting Thursday, February 17, at 6:30 p.m. After 30 minutes learning Pilates techniques with a super-qualified Rabara instructor, Joe Porter, a Class A PGA golf instructor at Windsor Greens Golf Center, will translate that into drills to improve your swing. There will be between 3 and 7 other students. Cost: $120.

Full disclosure: I’ve been studying at this studio for two decades. I’m not a paid shill but I am an enthusiastic proponent.

I believe the Pilates principles — flexibility, balance, and core strength — are as vital to my longevity as they are to an athlete’s success. But I warn anybody who will listen: Be sure your instructor has valid credentials and is not the graduate of a weekend course. Your body is a terrible thing to waste.
