I’ve shown this movement progression to hundreds of people over the years. It is without a doubt one of the most potent mobility exercises I’ve ever learned. When practiced regularly, it has the ability to improve movement in the hands, wrists, elbows, shoulders, upper back, neck and even help breathing become easier. I learned the first 2 parts of this combo during my Crossfit days. The second 2 parts I learned from one of my mentors, Carl Paoli.
