Caryn Connarton, owner of Beyond Fitness Pilates Studio, has earned certifications in nearly every fitness fad of the last decade. Though spinning strengthened her quads and aerobics bolstered her endurance, only Pilates delivered full-body results. In her opinion, it's the best form of exercise for people who want to increase their flexibility, improve their posture, and build longer, leaner muscles. At her studio, Connarton and fellow instructors lead group classes that often incorporate several props—BOSU balls build core strength, foam rollers stretch muscles, and rubber chickens tone participants' sense of humor. Instructors also offer private and semiprivate equipment sessions and specialized workouts for specific populations.
