...look outside of the box i.e. diet, rest/recovery, and supplementation. All have to be up to par in order for goals to be achieved. Remember, there are plenty of variables other then training that could hinder growth. Take into consideration all to try and nail the culprit.
Solid info bro. :igok:
Pers I just remembered that several years back someone posted a question exactly as yours. I replied with a little "trick"

of mine per se hehe, and it worked killa for them. Others posted that they had also tried it with good results. If you really wanna bring out seperation in your upper & inner back, read on...
As the last exercise of your back workout, jump on the Hammer Strength row machine. You want your hands higher than normal at the contraction, so adjust the seat so that its low enough so when you do a rep, your thumbs are around nipple-level. Perform the rows 2 hands at a time, not 1 hand. At the contraction stage of each rep, HOLD IT there for 3 full seconds and SQUUEEEEEZE your upper/inner back muscles as hard as you can. Use a weight that allows you to get 12 reps like that. So the 13th rep you can't hold it for 3 seconds, so hold it for 1 or 2 seconds or long as possible. Continue on doing as many reps like that. When you can no longer hold it at the contraction stage, bang out as many reps as you can until failure. You will be fried fosho.

Rest 2 minutes, and do 1 more set in the same fashion. Since you will be spent, you won't be able to get 12 reps with the 3 second contraction if you use the same weight (if you CAN, yo ass slacked on the 1st set!

)...so just do as many as possible...9,10, whateva. Then do exactly as before...as many as possible for a 1-2 second contraction, followed lastly by as many reps as possible until failure. If you follow this to a T, the next day you will be feeling some sore muscles you never knew you had before in the upper & mid back.
Try ending your back workout with this 2-set regimen for 8-10 weeks, then holla back with the results you see in the mirror when you hit a rear double-bi brah.
