Isokinetics will give you big muscles and/or hideously deformed arms

One realizes that the illustration on the right is supposed to represent movement, but it just looks like some dude with an unbelievably lumpy arm. And a tiny Johnny Tremain hand. Is this really the image you want to place alongside your product, Powerex? (Also, the guy on the left looks like he’s doing or about to do something auto-erotic. Be careful! Remember what happened to David Carradine!)

But really, what’s to worry about with all this? The Isokinetics program is so revolutionary, so guaranteed to succeed, “breakthrough” is spelled “breakthru.” What’s not to trust?
