I read the two original white papers/bulletins by Art Jones. Probably when I was 18 or 19. Excellent source of applied theory concerning training. Might suggest every potential serious BB'er take a glance at either of them , if given the chance. Straight to the point stuff in #1 & #2. And common sense.
Had a chance to work with a whole line of Nautilus equipment (before the gym went belly up..main reason was the gym owner let his "buddies" workout free...can't run a business that way). Used the original hip and back machine, pullover machine, shoulder machine, etc. That nautilus cam was indeed something else. The information on the points of leverage/force is well worth the reading time alone. One or two sets on any Nautilus machine could be the match for most men. True, Viator was the exception among the workout beast. A lot of physical rehab equipment is based on the Nautilus design. Which I believe Jones made most of his money off of.
Can easily apply Jones ideas to the common BB/DB, chinning or dipping bar. Try not confusing the majority of Mentzer's ideas with the original concepts of Jones. Crack, crank, AD, crystal or whatever you want to call it, really did plow under Mike Mentzer. Good Luck.
