Alright, someone told me that it was a thing to work on speed, not power something about bruce lee practicing on newspaper for 1inchpunch, like im supposed to put holes in the paper.. but with it hanging from 1 string all i manage to do is bend the paper inwards on both sides, and make it start spinning, and go up far. so i have to re adjust the paper after 1-3 times hitting it

It sounds nuts to me.

But, hey. Maybe he knows something I don't.
