dizzle, it's true for almost any of us. 99% of trainers don't have the need to start targeting "width", "thickness", "density", "inner back", "inner chest", "teardrop", "rear delts", "intercostals", "horseshoe" and any of the other FLEX mag nonsense that gets pounded into people's heads.
you look at my back and it's wider and thicker than ever. my "secret"? i do pullups and rows with whatever grip helps me feel it in my back the best. either it's contracting or it isn't. width comes from lats and teres major. "thickness" is traps and lower back. your back hardly gives a shit where your hands are on the bar.
