Slide a resistance band over your legs, letting it sit just above your knees.
Start on all fours with your hands directly under your shoulders and your knees directly under your hips.
Keep your right knee at a 90-degree angle as you slowly raise your leg to the right until it is parallel to the ground. Avoid lifting your right hip, as you should keep both hips squared toward the floor. Keep your core tight and your torso stationary so you don't twist out to the side.
With control, lower your leg back to the ground.
This counts as one rep. Complete two sets of 10 reps on each side.
