Seated 8 Leg Crunch

The Seated 8 Leg Crunch targets your core muscles while engaging your hip flexors. This exercise is performed in a seated position, allowing for controlled movement.

  1. Sit on a bench with your back straight and feet flat on the floor.
  2. Lift your legs off the ground, bending your knees at a 90-degree angle.
  3. Engage your core and lean back slightly while bringing your knees towards your chest.
  4. Extend your legs back out without touching the ground, then repeat the movement.

How to perform the Seated 8 Leg Crunch

  1. Set up. Set up in a stable, balanced starting position appropriate for the Seated 8 Leg Crunch using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your abdominals rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
