Barre is a ballet-inspired exercise that combines elements of yoga, Pilates, and ballet. It is a low-impact workout that focuses on strengthening the core, improving posture, and increasing flexibility. Barre classes typically involve a combination of small isometric movements, stretching, and light weights. The exercises are designed to target specific muscle groups, such as the arms, legs, and glutes. Barre classes are often accompanied by music and can be adapted to suit any fitness level.
