Start on all fours with your hands directly under your shoulders and your knees directly under your hips. A booty band should be around your thighs.
Keep your right knee at a 90-degree angle as you slowly raise your leg behind you until your thigh is almost parallel to the floor. Pulse your flexed foot toward the ceiling by squeezing your glutes.
Your back should remain perfectly still in a neutral spine.
Return to your starting position to complete one rep. After your set is complete, switch legs and repeat.
