How to do it

Starting position

  1. Lie flat on your back on the floor
  2. Rest your arms comfortably at your sides
  3. Lightly press your palms into the floor
  4. Extend both legs straight and bring them together

Movement

  1. Engage your abs and slowly raise your legs
  2. Raise until your pelvis lifts slightly off the floor
  3. Slowly lower your legs back toward the floor

Breathing

Exhale as you raise your legs and inhale as you lower them

Trainer tips

  • Lift your legs while keeping your lower back against the floor
  • Stop before your lower back lifts as you lower
  • Maintain tension in your abs

Cautions

  • Lowering your legs too low poses a risk of lumbar injury, so be careful
  • Lifting the lower back and forming an arch
  • Throwing the legs with momentum

If you feel pain during the exercise, stop. If it continues, talk to a professional.
