It's sick, just sick, the way these losers will invent crap to take your money. Cons have been around a long time but what is sad is that some of these lifters actually believe in their ideas!
The biggest ripoff to me was Joe Weider, when he put his name on every BB principle there was at the time. Remember? The Weider Confusion Principle, Weider progression principle, Weider Forced Rep Principle, etc. etc. - only he didn't try to make money off them, he just wanted his name bigger than his magazine, his name on the BB contests, his name on the (often crappy) BB supplements, and his name on some of the world's worst BB equipment.
I wouldn't want my name on a bench with a leg extension that you would hit your heels on the bench's feet in the return swing...or a rubber band workout bench that the steel tubing actually flexes when you use it. (I actually found one of these: use it to hold my radio). He's called the 'Father of Bodybuilding'...and in a sense he is: his rag was the first one to be filled with advertisements with endorsements by 'Roiders claiming they got that way with his products, exersize routines that would only work for 'roiders, and stuff thought up by people who don't even lift. Yeah, he led the way.
