What causes these natural body positions (see details)?

Start by opening your hand all the way. Now slowly close it, stopping briefly at natural stopping points. I count three such positions. For the last one, the hand is almost but not quite closed. I find a similar situation for any arm or leg movement and also for opening and closing my mouth.

What causes the muscles to be able to relax in these positions? I would guess that we move to these positions when we want to hold a pose, for example a batter in baseball waiting for the next pitch.

If I understand what you’re describing, I think it’s about muscle and tendon contractions. I have to force my hand to stay open, and when I relax it it goes to one of those positions, then I again have to force it to close. I’m picturing you opening and closing your mouth to see what happens ;D
