Jorgen Peter Muller (1866-1939) had a reputation for being everything from pornographic to a world famous hygienist and physical fitness guru. The Danish sportsman was, in fact, all-round champion athlete, Danish Knight of the Order of the Dannebrog, and author of the international best seller My System, published in 1904.
My System is a complete step-by-step guide to 18 daily exercises that nearly anyone can complete in 15-minutes. The book sold 2 million copies and was translated into 25 languages. Muller became famous for traveling around Europe and demonstrating his exercises while wearing only a loincloth and displaying his tanned, toned body. Shocking by all Victorian standards!
