The single-leg squat is a strength training exercise that targets the muscles in the legs, particularly the quadriceps, hamstrings, and glutes. It involves balancing on one leg while lowering the body into a squat position, then returning to a standing position. This exercise helps improve balance, stability, and overall leg strength. To perform a single-leg squat, stand on one leg with the other leg extended slightly in front. Bend the standing leg at the knee, lowering your body while keeping the extended leg off the ground. Aim to keep your torso upright and your knee aligned with your toes throughout the movement.
