By law, strengthening-product demonstrations in infomercials must look like sex acts. There's the Shake Weight, obviously. And now, there's the Free Flexor, a "revolutionary fitness product that introduces the patent-pending Circular Strength Technology to athletes and beyond." It's not quite as indecent seeming as the Shake Weight, perhaps, but it's still not something you should do around your mother. Also, it's not free. It's $39.95. Via Consumerist.
