I hear this a lot, but doesn’t corroborate with my experience seeing folks at calisthenics parks.

This [1] is what I look like with only body weight training. Even if I could, I intentional don’t want to get any bigger given how it affects other sports I play and my current preferences (slightly impacted by my partner’s).

Interesting, maybe it's a function of body type? I naturally have an extremely slim build. Even lifting heavy every day I had less visible muscle than you, though it was noticeably more than when I was only lifting myself.
