How to Perform Chin to Chest Exercise - part of the women's fitness video series by GeoBeats. Hi, I'm Katie - trainer for Rockbody Bootcamp, Austin, Texas. I'm going to take you through a quick neck stretch, Chin to Chest. You just are going to very gently and easily bring that neck, bring that chin down to your chest. Stretching out right through each vertebrae to the top of the neck. Hold that for 20 seconds before releasing back to neutral position. And that's Chin to Chest.
