But you are trying to say that weighted punching is for arm/shoulder only punching. Which pretty much nobody does. But a lot of people do weighted punching.
As far as maywether goes it is both.

oh, most everyone BELIEVES that they are using the body to punch. In most cases they are wrong, or they don't do it nearly as well as they think. There are many subtle disconnections that severely disrupt the technique. On a superficial level it APPEARS that they are putting their body behind the punch, but when you know what to look for you can see that the connection is really very poor, and can be undermined to the point of being essentially non-existant. When that happens, the punch is all arm-shoulder strength driven, with zero body connection. But people continue to be fooled into thinking they've got that connection and are punching with the body driving it.
as far as a lot of people doing weighted punches, well yeah, and a lot of people don't. If you see it as beneficial, then do it. I don't.
I'm not sure what you are trying to show me in this video clip. The fact that he's using heavy gloves? Well he's a boxer, the rules of the game require gloves so he must be able to use them. That doesn't mean it's the best or most efficient way to punch.
as far as his body connection, I see a lot of stuff where it's lacking. Some has it, but it could all be improved. Still, he's a tremendous athlete and clearly he has been very successful and is a very good boxer. He's been able to take what he has and use it quite well. That does't mean it's the best way possible. Athleticism can take one a long way. You don't need perfect technique to be very effective. But what do you want from your training? It's up to you.
