Setup
- Lie on your side with your legs extended straight, angled slightly in front of your hips to create a shallow 'banana' shape for stability.
- Prop your head up with your bottom hand or rest your head on your extended bottom arm.
- Place your top hand on the floor in front of your chest for balance and stack your hips vertically.
- Engage your core to create a small space between your waist and the floor, ensuring your spine is neutrally aligned.
How to do it
- Lift your top leg to hip height, keeping it parallel to the floor and your foot flexed.
- Inhale and kick the top leg forward as far as possible without rounding your back, using a controlled double-pulse motion.
- Exhale and sweep the leg back behind your hip line, pointing your toes and squeezing your glutes while keeping your torso perfectly still.
- Perform all reps on one side before switching, maintaining a steady, rhythmic tempo.
Form checklist
- Keep the hips stacked vertically; do not let the top hip roll forward or backward during the kick.
- Maintain a 'quiet' upper body—the torso should not rock or sway as the leg moves.
- Keep the moving leg at hip height throughout the entire forward and backward sweep.
- Engage the obliques to prevent the lower back from arching when the leg moves behind the body.
Pro tips
- Focus on 'reaching' the leg away from the hip socket to create length and maximize muscle engagement.
- Press the bottom leg firmly into the floor to act as an anchor, which increases stability and core recruitment.
- Visualize your torso being set in concrete; only the hip joint should be mobile.
Make it harder
- Place your top hand behind your head instead of on the floor to significantly increase the balance challenge.
- Add a small resistance band around your ankles to increase the load on the glutes and hip abductors.
