Barre exercise is a low-impact, full-body workout that combines elements from ballet, Pilates, and yoga. It focuses on small, isometric movements that target specific muscle groups to improve strength, flexibility, balance, and endurance. Named after the ballet "barre" (a stationary handrail dancers use for support), barre classes often use the barre for stability during exercises but also incorporate light weights, resistance bands, and sometimes a mat for floor work.

The workout typically emphasizes high repetitions with low weights or body weight, which helps tone and sculpt muscles without adding bulk. Barre exercises are known for building core strength, enhancing posture, and helping people achieve a lean, toned physique.
