Setup

  1. Lie flat on your back with your arms by your sides or tucked under your glutes for lower back support.
  2. Lift your legs straight up toward the ceiling until they are perpendicular to the floor.
  3. Engage your core by pressing your lower back firmly into the mat.

How to do it

  1. Inhale as you slowly lower your legs out to the sides in a wide 'V' shape, keeping your knees locked.
  2. Exhale as you use your inner thighs to pull your legs back together to the starting position.
  3. Maintain a controlled tempo, taking 2 seconds to open and 2 seconds to close.

Form checklist

  • Keep your lower back glued to the floor throughout the entire range of motion.
  • Ensure your legs remain fully extended without bending the knees.
  • Avoid letting your legs drop quickly; maintain tension on the adductors.
  • Keep your head and shoulders relaxed on the mat.

Pro tips

  • Focus on the mind-muscle connection by consciously squeezing your inner thighs as you bring your legs together.
  • Flex your feet (toes toward shins) to help maintain leg tension and stability.

Make it harder

  • Lower the angle of your legs toward the floor to increase the demand on your lower abdominals.
  • Add a pause at the widest point of the abduction to increase time under tension.
