Place a resistance band around your ankles or attach it to a low anchor behind you. Stand tall and hold onto a stable surface for balance if needed. Keep your core engaged and your torso slightly leaned forward while maintaining a neutral spine. Drive one leg straight back against the resistance in a controlled motion, squeezing your glutes at the top without arching your lower back. Slowly return the leg to the starting position while keeping constant tension on the band. Complete all reps on one side before switching legs.
