Re: Punching with weights
Not aware of actual studies. I think alot of people just do it because their coach told them to, and their coach did it because his coach told him to, and so on.
I don't punch with weights to improve speed becasue to me, I don't see how I will get faster punches by holding weights in my hands which just slow me down. Even if you can (or just feel like you can) punch faster when you put the weights down. I train for speed by punching as fast as I can, without sacrificing technique. Again I'm not aware of any actual studies, just my opinion.
