The Bulgarian split squat is a single leg squat performed with the rear foot elevated on a bench behind you. It loads the quadriceps and glutes of the front leg hard while demanding balance, hip mobility and core control. Lifters use it to build leg strength one side at a time, fix left to right imbalances, and get squat like stimulus with only bodyweight or light loading.
