Shift weight to the bent supporting leg. Engage glutes to drive the working leg back and up. Squeeze glutes and pause at full extension. Rotate foot slightly if desired. Slowly return to start, avoiding weight stacking. Alternate legs.
Squeeze glutes at the peak. Maintain a neutral spine. Engage your core. Control the movement; avoid swinging. Start with lighter weight to ensure proper form. Movement should originate from the hip joint.
