Reverse Crunch

  • Lying on your back, lift your legs in the air with your knees bent. Place your hands on the floor beside you.
  • Without momentum, use your lower abs to slowly curl the hips off the floor and into your chest. Slowly lower them back to the starting position.
  • This counts as one rep. Do 25 total.
