How to do the groin crunch

  1. Lie flat on your back with your knees bent and feet flat on the ground.
  2. Place your hands behind your head with your elbows pointing outwards.
  3. Engaging your abs, lift your legs off the ground, bringing your knees towards your chest.
  4. Pause for a moment at the top, then slowly lower your legs back down to the starting position.
  5. Repeat for the desired number of repetitions.

Sets and reps

Start with 3 sets of 10–15 reps, resting 45–60 seconds. When every set feels easy, add reps, slow the lowering phase or move to a harder variation.

Muscles worked

The main muscle is the abs. The hip flexors and inner thighs work as secondary muscles. See all ab exercises or every bodyweight exercise.
