Bullworker, it is a flexable, sort of length of rubber. It was used by the late rick rude, and although he had medicinal help I know other strictly natural big folks that use it. Pushups, 100 a day, 4 sets of 25 will give your neck and shoulders that bubble look. Charles Atlas uses isometrics to get big. Isometrics is pushing against an immovable object. Crunches are good also. A great female builder (Pillow) said it takes about 4 hours a day to get big and stay there. Hi pro low carb also is needed.
thanx,
