No problem Nat
It makes sense. I've come across people at the gym who don't like training back a whole lot because they can't "see" progress. I go by feel and love the feel of training back. And of course, like most, I do like to take a look at it so I go in the back of my gym where we have a posing area with mirriors in all angles so we can easily see our back, side, etc. all at the same time.
I used to always train in a tank top or tight shirt to watch all the muscles work, but now that I train in pants and a sweatshirt for the past year or two, all muscle groups are the same, I can't see any of them so I go off of feel and intensity.
Have fun hitting the back and focus on the feel and see if that helps.
