next to legs, i think the back is probably the most underdeveloped area.
I would add wide bar pull down to the list.
but the key mate, is not how much weight you pull. I'm in the gym every day watching people use too much weight. when doing a wide bar pull down, your ass should NEVER leave the seat, and your back should be fairly still. the only real motion should be shoulders and arms. this means a light weight
Not to shit on anybody's advice, but in MY PERSONAL EXPERIENCE, deadlifting has done nothing for the width of my lats. I'm fully aware that it works pretty much every muscle in your posterior chain, but I've seen no additional width in my lat spread since I've dedicated myself to powerlifting. I pull over 600 and should know by now.
Wide grip chin-ups , close grip chin ups, bent over rows, cable seated rows (on the bench, then sitting on a wooden box on top of the bench)- these are my supersets, and then pulldowns.
I found that when doing pulldowns, if you sit straight up, arch your back, stick your chest out, don't lean back(using the erector spinae), and imagine you're pulling the elbows to the ribcage, as opposed to pulling from the hands, it really isolates the lats and I always feel it (mind to muscle connection).
Straps really help, of course. I'm stronger than my grip.
Spongy hit it with the mind muscle connection. When doing any pulling, really focus on keeping your elbows in a single plane of motion and drawing them backwards. Doing this really helps contract the lats. One of my favorite exercises that really improved my lats (especially lower) is the cable pullover using the rope. I usually finish with these as they really help push blood into the lats. Just my humble .02!
I think back development is a genetic. I spend the least amount of effort on back but its one of my best body parts. my chest I have tried everything and its easily my weakest.
for back I do deads, bent over rows, pull ups and pull downs. nothing fancy. I have recently added in some rack chins and close grip cable rows but I'm not sure how beneficial they are compared to what I am already doing.
for width though specifically pull ups are my favorite.
I hit my back once a week looks like this and it feels amazing when its done
deads 2 warm up sets get heavy for 5 rep set add 4 add 3 add 2 add 1rm ,then a burn out set
bo rows 2 warm up sets then add weight 10 add 8 add 6
wide grip pull downs 10 8 6 4 adding weight super set db lawnmower pulls same weight heavy 4 sets 8
low pulley close grip rows 10 8 6 4 adding wieght
my favorite work out just figured I'd share it b/c it feels so good and I am constantly getting stronger doing it
also I do 3 to 5 sets of pull ups with every work except back as warm up in between my first exercise so if I was doing legs I would add pull ups in between my squat sets seems to keep the wings growing
