The plank is a common core exercise used to strengthen the Anti-Extension pattern of our core.
How to perform the Plank:
1. Lie on your stomach on a comfortable surface
2. With your hands just outside of shoulder width and forearms on the ground, dig your toes into the ground, straighten your knees into full extension and lift your body off the ground, pushing up onto your forearms
3. Hold this position with a neutral or slightly flexed spine, whilst breathing into your stomach for the prescribed amount of time
