If you go to the Wikipedia page for Mr. Jones, you will find links to the famous Nautilus Bulletins. They reveal a fascinating individual. I like this quote from his son, William E. Jones:
Arthur was a showman, the P. T. Barnum of exercise. He invited one and all to come and see what he had created, and why it was better than anything else. He would argue with someone for hours, trying to convince them of why his machine was better, and of the proper methods of exercise.Anyone else remember climbing up into the enormous, blue, Willy Wonka-esque Nautilus leg press? Strap yo' self in and begin the journey to bigger, stronger quads.
Cams and pulleys....isolate the muscle and work it through the entire range of motion; work it hardest in the range where the mechanical advantage is greatest. Isolated strength and hypertrophy. Even in 1995, I sat for hours in a Wash U graduate level physical therapy class, as my instructor droned on about mechanical advantage and cams and lever arms. You know, this dude was a cool teacher, but I'm not sure he'd actually trained any way but sitting down in a machine. But he sure knew how to explain why a cam was different than a pulley.
Then we spent a bunch of class and lab time on isokinetic stuff with the giant Kin-Com monstrosity. And the majority of our practical exposure to resistance training came in the form of going from MedX machine to MedX machine in the hospital wellness center, drilling on how to set up the contraption for its stated purpose. Each muscle, gloriously isolated, by marvels of engineering design.
Function, in context, was never really discussed, except maybe in the OKC v CKC strengthening of the quad. Should you do leg extensions or not? Zero to 30 degrees? Are wall slides better?
The Arthur Jones/Nautilus/MedEx cult of personality and practice live on, for many in the medical profession. I think how far I've come over the last 10 years--I was lucky enough to run a few dudes--dare I say "old-school dudes"--who did not drink the kool-aid. They helped me appreciate the history of the iron game and of physical education; helped me understand the capacity of the human body at the elite levels of sport, and that similar principles of training can be used in rehabilitation and wellness. Vive la gravity--sans cams and pulleys, Mr. Jones.
