I have noticed many weight trainers, including myself, have quite broad shoulders. Is this an illusion due to added muscle, or is this truly a change in skeletal shape?
I do not have a 'control' to this 'experiment' as I lifted during puberty and thus could have changed body shape due to hormones etc. I was however quite narrow and skinny when I started.
Additionally, could certain exercises that 'pull' on your joints (like wide grip pullups/pushups) accelerate or increase this effect?
