Join fitness pro, Fitz, for this simple yet challenging move that will engage every muscle in your core. Try it with your legs bent, as shown in the video, or tone it down and do it with your knees bent. The Windmill allows your obliques to engage at their full range of motion and will help your low back grow strong as well. Once you master The Windmill as shown, try it with a medicine ball in between your feet.
