Hardcore Pilates

When champion long jumper Wayne Davis pulled a hamstring during the 2000 Olympic trials, he turned to Pilates to augment his recovery—and was instantly wooed by its therapeutic and athletic benefits. Today, together with fellow certified trainer Lauren Smith, Davis blends weight training, yoga, and traditional Pilates into classes at his studio, Hardcore Pilates. Each Pilates class of four to six students includes exercises on an Allegro Reformer, whose roller- and spring-propelled platform helps strengthen torsos and straighten students’ posture. Rounding out its staff of all-star athletes, the studio also employs a former pro football player, who leads spin classes set to lively music and incisive play-by-play analysis. After class, one-on-one stretch therapy helps refresh muscles and connective tissues, relax joints, and expand range of motion.
