Actually this makes me nervous!

I have a small build and it really doesn't take much to make my head bob all over the place in sparring!

I never really equated movement of the head with damage though - I guess I kinda thought if you move because you're small you're just not absorbing as much power because you don't have the same inertia as a heavier person would - maybe that only works if you move with your whole body rather than just your head though!

Does this mean the old fashioned neck strengthening exercises really are pretty important?
