How to do it

Lie on your back with legs extended and arms at your sides. Keeping your lower back pressed down, draw both knees up toward your chest while curling your hips slightly off the floor, then lower with control back to the start. Move slowly and keep tension on the abs.

  1. 1Your lower abs pulling the knees and hips up
  2. 2A small posterior tilt of the pelvis at the top
  3. 3Controlled tension as you lower the legs

Common mistakes

  • Swinging your legs to create momentum
  • Letting your lower back pop off the floor on the way down
  • Pulling with the hip flexors instead of curling the pelvis
