The plank is an excellent exercise for core conditioning, it supports correct posture and works the glutes and hamstrings.
- Start in a standard plank position but with feet wider than shoulders and forearms parallel under shoulders
- The object here is to maintain a strong neutral spine while rotating from one side to the other
- Try to move the shoulders and hips together as a single unit
- Pull belly button in and squeeze your butt while rotating, make sure you go 180 degrees around onto the side of the feet as the video illustrates
