Interesting and I've observed this as well personally. Was always bigger and got complimented on looks quite a lot pre 2020, but during the big lockdown got leaner (and smaller) from my home workouts and suddenly started getting a lot of attention from hotter and younger chicks. Started getting called hot and sexy quite frequently as opposed to good looking. Have put on a bit since then but am trying to get back to that level. Noticed that I did have less visual pop with clothes on when leaner though. So while I did better in the interactions themselves, getting leaner reduced my presence and I noticed less IOIs pre approach when wearing shirts (wife beaters were another matter, lots of IOIs then)
The solution is to do a lean bulk. For example, having 15% is a little bit too much, even for starting a lean bulk.
Sodium manipulation and a clean diet and choosing combination of macros can help with water retention and can improve facial aesthetics, along with cardio on this one.
Same with meal timing, so most of the carbs will go into the body as glycogen and minimize getting fatty, so the muscles appear as big as they can, while skin is as much as paper.
Huh, been lifting for a long time and have never explicitly heard about muscle density before. Of course you see guys who are small and ridiculously powerful but never thought about the inner workings before. Interesting.
It's more about types of training which activates different of muscle fibers.
