weve got one of them old nautilous machines in our gym and i realy dont rate it,,,, some love it, most dont...........
i always like to start my back day with some kind of pulldown movement,, if your starting out wide grip chins are great strength and mass builders, if u cant manage 2 or 3 sets of 10 just make your reps add up to 20 or 30, even if your doin 4 reps, then 3 reps etc etc until u get your strength up. The form your aiming for is as if your trying to elbow somone behind you....
barbell rows, pulling to the waist... probly the number one exersize for adding width and thickness,
some kind of machine row, either cable row, hammer row etc etc etc, realy big squeezes on these
followed by deadlifts, building upto a low rep last set 3 to 5 reps
i like to do traps on back day to, so id finish it off with bb shrugs, nice full strict movement, with squeeze at the top
doesnt matter how u arange your sets and reps, thats a personal thing, im a low volume trainer so 2 or 3 warm ups and 1 or 2 heavy sets of 6 to 8rep, others grow from 3 to 4 sets per exersize, upto you to experiment on what works for your own body..one thing i will say is you will never have the back u want if you just move the weight from A to B, youve got to learn how to feel and contract your lats hard..
