Does anyone else use one of these? I bought my first just over 40 years ago. Green handles and a sort of plastic reinforced with steel cord. The model in the brochure was a superbly fit young athlete by the name of David Prowse (later became involved in intergalactic war and forces of evil, suffering from heavy breathing). But of course I never believed he got that way JUST by using a Bullworker. The present Bullworker is ok but not as well made. The exercises push one muscle against another and offer excellent stretching potential. But you know, they really do make you feel great if you workout with one of these. Maybe even become a Jedi Knight. Recommended.
