I was watching a video of Canelo in the gym punching the heavy bag. He was concentrating on heavy-hitting hooks to the body, with both hands. Really trying to hit the bag as hard as he could. Punch after punch.
What he wants to do with that body punch is plant his feet and get maximum leverage in a hook to the kidney area. That is his power punch (reminds me of Micky Ward). It is Canelo’s game winner.
But it is also his maximum vulnerability because when he plants his feet to throw the body punch, that’s when he is most stationary and vulnerable, as his focus is on hitting his opponent’s kidney area, not on his own defense, particularly with regard to a counterpunch head shot from the opponent.
