Looking for guidance on a back workout routine. I rotate between three groups: legs, chest, back. Not super strict, just as often as I can get into the gym. I am at the point where I have started to add in more free weights and less machines. Found some good ones for legs and chest, but not as many for back. Plus the machines I use for back seem pretty good anyway. Also, some places online listed deadlift as a back workout but it seems like more of a leg workout to me.
Ideally you would use a freestanding barbell, but a dumbbell modification is perfectly okay. You'll lose out on working a lot of your stabilizers and will likely have to favor your back or legs with positioning at a smith machine and it makes the overall movement of the exercise pretty awkward and ineffective.
