Exercise of the Week: Swiss Ball "Stir the Pot"

This core exercise was popularized by low back specialist Dr. Stuart McGill. In order to perform the exercise:

1. Get into a plank position with your forearms resting on a Swiss Ball.
2. Maintaining this plank position, circle your forearms in one direction until they come back to center. Then circle your forearms in the other direction. Keep going until all reps are complete are the time is up.

You can perform this exercise for reps (doing 6-10 circles in each or direction) or go for a specific period of time (30-60seconds). To increase the difficulty of the exercise you can use a smaller ball, narrow your feet or elevate your feet.
