Secondary Muscles

A core exercise performed lying on the back where you alternately raise and lower each leg. Develops hip flexor and lower abdominal strength.

Instructions

  1. Lie flat on your back on a mat with your legs extended and your arms by your sides, palms down.
  2. Keep your lower back pressed to the floor throughout the movement.
  3. Raise your right leg to about 45-90 degrees while keeping it relatively straight.
  4. Lower your right leg back down to the starting position without letting it touch the floor.
  5. Immediately raise your left leg in the same manner.
  6. Lower your left leg without touching the floor. One rep equals one raise on each side.
  7. Continue alternating in a controlled manner for all repetitions.

Tips

  • Press your lower back to the floor to prevent lumbar strain.
  • For an easier variation, bend your knees.
  • For a harder variation, lower your legs closer to the floor without touching it.
  • Move in a controlled manner; avoid momentum and swinging.
  • Keep your core engaged throughout the movement.
  • Place your hands under your glutes for additional lower back support if needed.

Recommended starting values

Sensible novice starting points for each goal, for a lifter aged 25–40. Scale down for smaller frames or older lifters. Treat the first set of any session as a discovery set.
