Hey bros, I nedd some serious upper back help, I have got a space between my shoulder blades that is empty. My lats are proportionate to the rest of my body but, traps and rhomboids are non existant. Right now in my workout I do chins, bent over rows, and cornor row. I have no access to a low pulley, or tbar row so thee are out. I would like to do deads, but I am afraid my low back wouldn't recover enough to due squats. Heard powercleans are good, but don't know how to perform them. I am just coming off a nasty shoulder injury that I think was a result of this muscle imbalance in my back. Please give some advice.
