Crunch (on stability ball)
The crunch on a stability ball is an effective exercise for targeting the abdominal muscles while also engaging the stabilizing muscles of the core. By performing the crunch on an unstable surface, you increase the demand on your core to maintain balance, which can lead to greater muscle activation.
