One thing I noticed in looking at before/after photos of guys with good shoulders, is that the shoulders genuinely seem to get wider over time. This is in addition to building up the delts. It seems that the position of the shoulder girdle actually changes over time.
I don’t think this is just an illusion.
Any ideas which exercises might do this (over the period of a few years)?
Heavy overhead presses? Bench press? Weighted pullups/pulldowns?
