Setup
- Lie flat on your back on a mat with your legs fully extended and arms by your sides for support.
- Press your lower back firmly into the floor to engage your deep core and stabilize the pelvis.
- Lift both legs straight up toward the ceiling until they are perpendicular to the floor, keeping your feet flexed.
How to do it
- Inhale as you slowly lower your legs out to the sides in a wide 'V' shape, maintaining straight knees throughout the movement.
- Exhale as you use your outer glutes and core to pull your legs back together to the starting vertical position.
- Maintain a controlled tempo, taking 2 seconds to open the legs and 1 second to bring them back together.
Form checklist
- Keep your lower back glued to the mat; do not let it arch as the legs open.
- Ensure the movement is strictly lateral, keeping the legs in the same vertical plane.
- Keep your toes pointed toward your shins to maintain tension in the legs.
- Avoid using momentum; focus on a slow, controlled 'split' and 'close' motion.
Pro tips
- Focus on 'pushing' the air away with your outer thighs as you open to maximize gluteus medius activation.
- At the top of the movement, actively squeeze your inner thighs together to engage the adductors before the next rep.
Make it harder
- Lower your legs to a 45-degree angle relative to the floor instead of 90 degrees to significantly increase the demand on the lower abdominals.
- Wear ankle weights to increase the resistance on the hip abductors.
