Old fitness machines don't die..they just slowly rust away. Or do they? As in the Nautilus Machines that Arthur Jones produced. Any still in existence today? Is there a fitness machine Hall Of Fame & Museum anywhere on the planet.? His cam-action machines were unique at the time. I understand HammerStrength duplicates some of the Nautilus protocol but I'm not sure. Who else uses the cam action on their machines? What year did Arthur's Nautilus machines bite the dust (if indeed they did)? Obviously they were improved upon over the years,yes? Is Nautilus still going strong?
