I was curious about this one since I've only rolled my back before and wanted to see ways to roll other upper body parts. As always, Cathe explains everything very well as she guides through the workout. I was really surprised at how sore my lats were when I rolled them; it's not like I work them any more than any other part but I could barely put my body weight on it. I especially liked the Slide Straddle stretch and the Thoracic Open Book stretch (similar to paint the rainbow). I really liked this and felt like it had some mobility type stretches in with the foam rolling. It was a quick routine that you could easily add on at end of a workout or just by itself if you had knots or tension you wanted to get out. Another great addition Cathe; thank you!
