The way i see it is your hands will try to adjust to the extra weight so when you use something lighter it will just go. Similar to running with a heavy bag. Thoughts?
I've trained with gloves as heavy as 24oz, shadowboxed with weights, own a weight vest, wrist weights, ankle weights, you name it as far as heavy training I've done it. From my personal experience, no, it doesn't really build speed, I find it builds endurance (like crazy) but I don't notice speed gains from heavy training. If you do it all the time, you adapt to moving at that slow speed - you may initially feel a burst when you put on the lighter gloves but within a round or two you adjust. Different strokes for different folks though, some people may find that it works well for them, I dunno. I personally like training in as close to the conditions I'm going to compete in as possible - within reason. The last thing I want is to be surprised by something and taken out of my element on the day of the fight. Of course your hands and sparring partners may not last very long if you're using fight gloves all the time. I just remember how I felt before my first fight, after I put on the fight gloves and realized all the extra space I had to cover with my defense, not to mention realizing what I was going to be hit with. It scared me, shook my confidence. Don't want to go through that again.
16oz sparring 16oz bag Putting on tens for competition was a dream 24oz would of definately ****ed with ma timing, physically and mentally.
10 OZ for everything but sparring in my opinion. I think the 16 oz may build bad habit if being used constantly so use them when you have to. Even for sparring drills I do only use 10 oz. But I say no it won't build speed becoz your muscles aren't really working any more to push forward, they are working more to just keep hands up.
