Yea so those muscle behind your armpit but above the lats. How do you target those specifically with a single armed / isolation excercise? The ones on my right side are bigger than the ones on my left due to being stupid and never switching my grip up on deadlifts in the past i think (underhand left side, overhand right side). But now I'm recovering from an injury and can't deadlift. But the difference is so noticable i can feel it in my shoulder and it turns up when I flex. Feels like it's making my right shoulderblade stick out a little more or something. At first I thought it was a lat imbalance so I've been throwing in an extra set on the left side. Problem still not entirely fixed. Is there anything I can do, or do I just deal with it till I can deadlift again and switch up my grip?
