HOW TO DEVELOP A POWERFUL CHEST by Chas A Trevor
In this excellent 36 page ebooklet almost purely dedicated to Rib Cage Expansion was written during the Silver Era, focusing on many breathing exercises that can easily be practiced at home or in the gym with minimal equipment. I presonally use many of the exercises and find that they are actually beneficial to recovery. Chas A Trevor was a ghost writer for many of Joe Weiders magazines, and was very knwledgeable. His collection of ebooks available at this store are note found anywhere else. Enjoy!!
