Technically the phalanxes are the bones of the fingers and toes so i’m not using it completely correctly.
Essentially the first “joint” up from my fingertip of my middle and ring finger rests on forward and roundhouse while the side of my thumb is on short.
I never looked into how it was supposed to be held so it was what i came up with.
Regarding my pinkie i played guitar for a few years so i am used to it.
When I need to tap, I press the side of my right face on the kicks and use my fingers to push the punch buttons. This is because my left eye sees better then my right.
