Used the original Nautilus pullover machine (strapped in) with the front lat bar attached for pulldowns (curl grip) done right after the pullovers. Big time exercise, big time gains. Really gave deep ridges with-in the serratus formations & thick, full lats. Point of resistence on the elbows, where it belonges. Problem was, human nature being what it is, too many guy's added extra exerecises like BB row's, chins with the Nautilus machine workout. Put greater demand on their recovery abilites, so of course they didn't gain much or ever lost some size. Blamed it on the pullover machine, though the main training idea was to just use the pullover machine alone in any lat/back workout. Those three positioned resistence cam's worked well when following the muscle strength curve of the human body. Also used the original Nautilus leg machine (also strapped in) and one of the few time I got quite dizzy for a exercise. Worked the hips and lower back heavy, as well as the whole leg structure it's self. Good Luck.
