ABS

Reverse Crunch

BeginnerBodyweight

A crunch variation that flips the motion, lifting your legs and rolling your pelvis toward your chest instead of your chest toward your hips. It leans on the lower abs and doubles as a leg-raise-style movement for the core.

How to do it

  1. 1

    Lie on your back with legs extended and arms at your sides, palms down.

  2. 2

    Brace your core by breathing into your belly and tightening your abs.

  3. 3

    Keeping your arms on the floor, draw your knees up toward your chest with shins parallel to the ground.

  4. 4

    Once your thighs reach your midsection, contract your abs to curl your pelvis toward your lower ribs, lifting your lower back off the floor.

  5. 5

    Lower your legs back down slowly to the starting position and repeat.
