Bulgarian split squats are a powerful single-leg strength exercise that targets the quads, glutes, and hamstrings while improving balance and stability. Performed with the rear foot elevated on a bench or box, this movement places greater load on the working leg, making it highly effective for building lower body strength, correcting muscle imbalances, and enhancing athletic performance. Bulgarian split squats can be done with just bodyweight or intensified by using dumbbells, kettlebells, or a barbell, making them suitable for a wide range of fitness goals from strength development to functional mobility training.
