I think it’s more a matter of what you’re used to.
I used to squat like this all the time as a kid, on toes or flat-footed, it is surprisingly comfortable.
I still do it, and I’m in my fifties now.
Maybe you have to start young, but when you’re used to it, it’s second-nature.
p.s. I’m an average white bloke, not some fitness guru.
