This is just more annoying than anything, but normally at the gym and at home sometimes I will do some light bagwork with just wraps on... and get some good burns on the middle joints of my index and middle fingers... not sure if my form is wrong? I have been punching with my "whole fist", quoted from an earlier thread, and my alignment seems to be correct, and the coach normally tells me if Im hitting incorrectly... but it rubs those joints anyways. I wonder is this a technique problem with the way my punches land?
