Why when I tap only once at a time, it feels like my muscles are inflating like a balloon, but when I stream it feels way easier, like my hand is just completely relaxed?
The only thing I could think of is that when you tap once you can feel the contraction and relaxation of the muscles, whereas with streams your hand is in a consistent state, so there's no (significant) changes you could feel
Could be something else tho, but it's probably this
