How to do it

Lie on your back with your legs straight and your hands under your hips for support. Brace your core and lift your hips and legs straight up off the floor until your feet point at the ceiling, then lower under control without letting your feet touch down.

  1. 1Feel your lower abs curling your hips off the floor
  2. 2Lift with your core, not by swinging your legs
  3. 3Keep the motion slow and controlled on the way down

Common mistakes

  • Don't swing your legs to generate momentum
  • Avoid arching your lower back off the floor
  • Don't let your feet drop and rest between reps

Muscles worked

The bottoms-up mainly works the lower abs, with the upper abs, hip flexors, and obliques assisting.
