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 square toward the floor.
With control, lower your leg back to the ground.
Continue for 60 seconds on the right side, then switch to the left leg for another 60 seconds.
