A "Bun Burner" is a term often used to describe a type of exercise or fitness routine that focuses on strengthening and toning the gluteal muscles, commonly referred to as the "buns." This can include various workouts such as squats, lunges, and hip thrusts, which are designed to enhance the shape and firmness of the buttocks. In some contexts, "Bun Burner" may also refer to a specific fitness class or program that emphasizes these exercises. Participants typically engage in high-intensity workouts that aim to burn calories while targeting the lower body, contributing to overall fitness and body sculpting.
