Resistance Band Quadruped Glute Kickback (+ close up of wrapping technique)
Wrap a resistance band securely around your left foot and get onto all fours with your hands underneath your shoulders (holding the band handles) and your knees underneath your hips. Shift your weight into your right leg and lift your left knee off the floor. Then extend it straight up behind you and return slowly to the start. Complete all reps on one side, then switch.
