Straight Arm Bent Knee Crunch


Pro Tip

If you want to make this movement easier, keep your hands angled diagonally up and back so that they are not directly overhead.


How To

  1. Lie supine on the floor with your arms raised overhead and knees bent in front of you.
  2. Exhale and raise your chest up toward your knees while keeping your arms directly overhead and keeping your lower back in contact with the ground.
  3. Continue to raise your chest and arms up as far as you can while keeping your lower back still on the ground.
  4. Inhale and lower yourself down, returning to the starting position.
