Most anyone can get a superior lat/back workout without the aid of a lat machine or other cable equipment.Though either one can be a good tool for development, for the average BB'er .
I just finished this back training cycle a few weeks ago with good results in strenght and muscle envolvement.
DL-partials...pin's set just below knees (Power Rack)
Hi-pulls..BB..off of pin's (Power Rack)
Hi-pulls...DB's, alternate one side at a time..wide arch
Chin's...curl grip, close (weighted)
Chin's...medium hammer grip (Weighted)
Chin's...behind neck (weighted)
Pullovers...straight arms...heavy weight's, not just for stretching
One set only of each exercise, that's it. Rep's between 12 and 20 reps of each exercise. Usually when I reach 10 reps I'll take three breath's between reps, or so, untill I finish my rep goal for that specific exercise. I make a point of adding either weight or reps to each workout I do. This method is something along the Rest Pause/breathing squat form of training and can take quite a bit of mental effort, at times, to finish a rep goal. This also put's demands on the cardio system. Finishing a hard set I may be breathing like a steam engine. Good Luck.
