How to Do Groin Crunch

  1. 1
    Setup

    Lie supine on the floor with your lower back pressed against the mat, hands gently supporting your head with elbows wide.

  2. 2
    Setup

    Lift your legs, bending your knees to a 90-degree angle, and bring your inner thighs and feet together.

  3. 3

    Exhale as you simultaneously lift your shoulder blades off the floor and draw your knees towards your chest, actively squeezing your inner thighs together.

  4. 4

    Hold the peak contraction briefly, then slowly inhale as you lower your upper body and legs back to the starting position with control.

Tips

  • Maintain a constant squeeze in your inner thighs throughout the movement, even as you extend your legs, to keep tension on the adductors.
  • Focus on initiating the crunch from your core, imagining your belly button pulling towards your spine rather than just pulling with your neck.
  • Control the eccentric (lowering) phase, resisting gravity as you return to the starting position to maximize muscle engagement and prevent momentum.

Common Mistakes

  • ×Using momentum to lift the body rather than core strength reduces effectiveness; slow down the movement and focus on a controlled contraction.
  • ×Pulling on the neck to lift the head can cause strain; ensure your hands are only gently supporting your head, and your gaze remains fixed on the ceiling.
  • ×Failing to squeeze the inner thighs neglects the adductor engagement; actively press your knees together throughout the entire range of motion.
