How to do the reverse crunch

  1. Lie flat on your back with your arms extended along your sides.
  2. Bend your knees and lift your feet off the ground, bringing your thighs perpendicular to the floor.
  3. Contract your abs and curl your hips off the floor, bringing your knees towards your chest.
  4. Pause for a moment at the top, then slowly lower your hips 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 work as secondary muscles. See all ab exercises or every bodyweight exercise.
