Description

  • Lie on top of the stability ball, with the ball directly under your lower back.
  • Cross your arms over your chest.
  • Keeping your neck neutral, roll your upper back off the ball.
  • Return slowly to the starting position.

ProTip

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

Mistakes

  • Jutting the chin as you crunch up
  • Placing the ball too high up under the back instead of keeping it under the lower back
  • Letting the ball roll back as you crunch up
