I find yoga too monotonous and uncomfortable. I need more uncontrolled freedom of sensations to be satisfied (Si base).
I still do some simple yoga at home (sun salutation), because it has some benefits. But it's not really my thing.
Yoga seems more Ni/Se to me.
I think yoga has some Si connection, but it's more weak Si. Creative Si, Role Si or even PoLR Si. But not Base Si.
SEIs, have you tried yoga and what do you think about it?
