Start standing with your feet hips-width apart and your right foot on a slider, paper plate, or small towel. Place your hands on your hips.
Keep your toes on the slider as you extend your right leg back behind you, sliding your right foot backward and bending your left leg until it comes to a 90-degree angle. Make sure your left knee stays over your ankle.
Push through your left heel to come back to standing, sliding your right foot forward as you return to the starting position.
This counts as one rep. Complete 12 reps on each leg, then repeat for two sets.
