How to do it

Lie on your back with your hands under your hips or at your sides and one leg bent with the foot flat on the floor. Keep the working leg fairly straight and raise it up until it points toward the ceiling, then lower it slowly without letting it touch the floor. Finish your reps, then switch legs.

  1. 1Feel your lower abs and hip flexors lift the leg
  2. 2Press your lower back flat into the floor throughout
  3. 3Lower the leg slowly to keep tension on your core

Common mistakes

  • Do not let your lower back arch off the floor
  • Avoid swinging or dropping the leg down fast
  • Do not hold your breath; exhale as you lift
