How to do it

Lie on your back with your legs extended and lifted a few inches off the floor. Open your legs wide, then cross one over the other in a scissoring motion, alternating which leg is on top each rep. Keep your lower back pressed down and core engaged throughout.

  1. 1Feel your lower abs and inner thighs work as your legs cross
  2. 2Press your lower back into the floor to protect your spine
  3. 3Keep the motion controlled and led by your core

Common mistakes

  • Don't let your lower back arch off the floor
  • Avoid letting your feet drift too high; keep tension on the abs
  • Don't rush; control the crossing both ways

Muscles worked

The lying leg cross mainly works the lower abs and hip flexors, with the upper abs, adductors, obliques, and quads assisting.
