Description

  • Lie on your back and place a small rolled-up towel under the small of your lower back.
  • Place your feet flat on the floor about 12 inches apart and your finger tips to the sides of your head.
  • Keeping your neck neutral, roll your upper back off the floor and twist to one side.
  • Return slowly to the starting position and then repeat to the same side.

ProTip

  • Initiate the crunch at the head, then roll your spine up segmentally into a crunch

Mistakes

  • Jutting the chin as you crunch up
  • Yanking the head up with the hands
  • Reaching only the elbow forward instead of rotating the entire torso
