Can anybody tell me the benifit of this sort of padwork where the fighter throws arm punches two inches with no form and the trainer slaps his gloves? Is it just a flow or reaction drill? Do they do "real" padwork later with punches that they may actually throw in the fight? I've seen PBF do it and so at least it's not detrimental, but other than flow or timing or whatever I can't really see the point.
Its to worrk on muscle memory and fast twitch reactions ... if you can see, maybe not with that video - but with Floyd its must faster and different punches. He throws like 5 pattern punches then throws a sweeping left hook - or he throws a pattern and then doubles up to the body. Its all how the fighter reacts. It also helps when you're tired ... its so many punches being thrown and blocked ... hundreds of punches per round w/ the pads ... that when it comes to a live fight you'll be able to adjust. (depending on the boxer) I disagree with you saying those are arm punches ... those are real, short, crisp, accurrate punches. I don't know what made you think they were arm punches ... they're not doing that for power, its more for speed, accurracy, and defense.
