I drive 25 miles each way to use one in Mountain View Golds. Just the most awesome machine ever, old school plate loaded and NOTHING-NOTHING!!! hits my lats the way it does.
The BEST back routine I have put together-
Machine pullovers
Reverse grip pulldowns
Reverse grip barbell rows
Seated low handle hammer rows
Behind the neck pulldowns
Dumbell pullovers
Rack deads
Long workout but my back is EASILY my best bodypart. I have always done high intensity/high volume on back and I have always gained. If you critique my routine, there is little overlap- it is very well thought out, and I developed it over many many years of training. Give it a shot...
