How Inventive! (No. 7)

Who hasn't had to lift a heavy object at some point? In 1996, Michael Schaefer patented a method for demonstrating his "Powerlift" technique (U.S. Patent No. 5,498,162). The technique requires no tools and assertedly prevents back injuries.

Interestingly, the claims don't cover a technique for lifting an object. Rather, they cover a method of demonstrating the lifting technique. Assume for a moment that the patent satisfies 35 U.S.C. § 112 and its specification teaches how to use the lifting technique. Who would ever have to infringe the patent by demonstrating the technique that's already been taught?
