jolting your brain from a punch?
I use pretty thin bag gloves when I hit the heavy bag.
I notice that sometimes, when I throw a really stiff cross or hook,
my head will shake enough to hurt my brain, or at least give me
that sensation. Does this mean
1) my technique is off? I don't think I'm hitting myself in the jaw with my shoulder or anything like that, but could be something else.
2) I should use fluffier gloves?
I don't feel like I'm that strong of a puncher, and I want to know if I should be fixing my technique or if I should just use bigger gloves.
