How to do it

  1. Lie on your back with your knees bent and feet flat on the mat.
  2. Lift your legs until your knees are above your hips, with shins parallel to the floor.
  3. Curl your upper body until your shoulder blades clear the mat.
  4. Draw your right knee toward your chest.
  5. Place your right hand near your right ankle, with your left hand just below your right knee.
  6. Extend your left leg diagonally toward the ceiling.
  7. Switch legs smoothly, reversing your hand placement to match the bent leg.

Form cues

  • Keep your pelvis quiet.
  • Breathe evenly through each switch.
  • Keep your shoulders away from your ears.

Common mistakes

  • Arching your lower backAim your extended leg higher so you can maintain your lower-back position.
  • Pulling hard on your kneeUse a light, guiding grip rather than tugging your knee closer.
  • Jutting your chin forwardLook toward your thighs while keeping a small space between your chin and chest.

Safety

Fatigue during the sustained curl can strain your neck, while extending a leg beyond your trunk control can irritate your lower back.

  • Start with short sets before adding repetitions.
  • Rest your head on the mat if your neck tires.
  • Stop if you feel sharp pain rather than muscular effort.

If you have ongoing neck or back pain, ask a physiotherapist about a suitable modification before using the curled-up version.
