im 5'9 , just started boxing about 1 month ago. I feel im pretty fast for my weight because a lot of the guys i spar with dont expect me to go explosive on them out of no where. I feel my stamina and power are fine and I know how to increase them if I want to, just want to know several methods to increase speed. Will punching heavy bag increase speed, Ive noticed a good increase in my left arm (im right handed) it use to be pretty slow and weak, now its a good hit.
