Setup
- Begin in a quadruped position on hands and knees, with wrists directly under shoulders and knees under hips.
- Extend your right leg straight back behind you, resting your toes lightly on the floor.
- Engage your core and maintain a neutral spine, looking at a point on the floor just ahead of your hands.
How to do it
- Exhale as you lift the straight leg and sweep it in a wide, controlled arc out to the side, aiming to bring it level with your hip.
- Inhale as you reverse the movement, tracing the half-circle back to the starting position behind your body.
- Maintain a slow, 2-second tempo for both the outward and inward phases of the arc.
- Complete all repetitions on one side before switching to the other leg.
Form checklist
- Keep your hips square to the floor; do not let your pelvis tilt as the leg moves laterally.
- Ensure your arms remain locked and your chest stays pushed away from the floor.
- Keep the moving leg completely straight with the knee locked out.
- Avoid arching your lower back; keep your navel pulled toward your spine.
Pro tips
- Imagine you are drawing a rainbow with your big toe to ensure a smooth, high arc.
- Focus on keeping the stationary hip still; if it shifts outward, reduce the range of motion of the moving leg.
Make it harder
- Wear ankle weights to increase the load on the glutes and hip abductors.
- Pause for two seconds at the widest point of the arc to increase time under tension.
