Start by grabbing the rings with your thumb wrapped around in a hook grip.. Start the ring pull-up by squeezing your butt and abs then pull your ribcage down. The feet should be pulled tightly together with the toes pointed and legs extended in front of the body. Pull your shoulder blades together as you begin to strongly pull the elbows down and behind. Don’t “break” your neck by looking up in order to get your chin above the bottom of the rings. Keep the spine neutral and abs engaged during the entire pull. On the way down keep actively engaged with both the core and the shoulders throughout the movement and especially at the bottom. Do not let your shoulders dis-engage.
