Been gymmaxxing and have encountered MAJOR chafing around lat area...

Is this a subhuman trait signalling my frame is not supposed to be holding this amount of muscle mass, despite only being 150lbs at 5'10 (lean)

it mostly just means you need to wear better fitting clothes.

is it on the upper inside arms or the lats themselves?

It is on the upper lats, when my arms are relaxed the rash is fully covered, and I noticed the rubbing today doing rows during my pull day

Narrow and/or upswung clavicles?

your grip is probably too narrow for your anatomy in that case, switch to using a wider grip for rows.

they look somewhat like the two right pictures, and each clavicle is about 17cm long
