Kneeling Leg Half Circle

  • Beginner

This isolation exercise improves hip mobility and strengthens the glutes and adductors by moving the leg through a controlled lateral arc. It challenges core stability and spinal alignment while targeting the hip stabilizers.

Muscles worked

  • Glutes
  • Hamstrings

Secondary

  • Quadriceps

Equipment

  • Body weight

Setup

  1. Begin in a quadruped position on hands and knees, with wrists directly under shoulders and knees under hips.
  2. Extend your right leg straight back behind you, resting your toes lightly on the floor.
  3. Engage your core and maintain a neutral spine, looking at a point on the floor just ahead of your hands.

How to do it

  1. 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.
  2. Inhale as you reverse the movement, tracing the half-circle back to the starting position behind your body.
  3. Maintain a slow, 2-second tempo for both the outward and inward phases of the arc.
  4. 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.
