We've all seen those silly commercials for the Shake Weight™. That can't be effective! However, a beautiful babe can. You'll be beasting those biceps while your cock reaps the shivery rewards. These are the kinds of incentives that would get us to the gym. Although if this kind of workout were allowed at your local Planet Fitness, we're sure the only thing that would be getting exercised would be people's eyes and hands. (Because we'd all be lookin' and fapping). But that's gotta burn at least a few calories, right?
