Students use breath to support the long, flowing movements of Pilates exercise, reinforcing their limbs with lean muscle within a safe range of motion for low-impact, core-strengthening exercises. In barre classes, bodies bend and stretch in a workout that combines ballet, aerobic motions, and Pilates into a single workout. Instructors pick up the pace with tower machines, which strengthen weaker, undeveloped parts of the body overlooked by other workouts, and cardiolates to blend Pilates movements with heart-pumping exercises. Reformer machines—another form of equipment developed specifically to enhance Pilates—employ a clever system of pulleys and straps centered on a gliding platform. In private lessons, teachers cobble together any combination of contraptions they feel most benefits their charges, providing a comprehensive education on Pilates’ function, terminology, and history, including a lesson on the day Joseph Pilates tore the Liberty Bell in two with his abs.
