Named after Joseph Pilates, “Pilates” is a method of exercise that consists of core strengthening and low-impact muscular endurance and flexibility movements. Proper postural alignment, breathing, core strength and muscle balance are emphasized, and precision of movement is stressed over number of repetitions. Joseph Pilates developed the basic Pilates exercises and a variety of Pilates equipment in the 1920s. Only a mat and a towel are needed for this class.
