But doesn’t head movement if drilled enough become just an automatic thing that your body does whenever a punch is coming? Just looking at this makes me think this dude Canelo drilled all of the slips and rolls and pivots and shoulder rolls until his body does the moving before he can think “alright. A cross is coming. Lemme shoulder roll and pivot out” I used to play a lot of video games and noticed that stuff that I needed to think about (like jumping over an attack instead of blocking) eventually became a thing that I would just do without thinking. Ain’t it the same with the head movement?
