lol.
Drago are you looking to train for speed or endurance?
I've done it occasionally. Not sure how beneficial it is. I think you'd have to be consistant with it. It's like training with bag gloves then putting on 18oz sparring gloves. You feel a difference. Problem is I've found is that because of the extra weight people slow their punches down. If you're looking for speed you don't want to do that.
