How do the really fast guys get really fast? I can hit pretty hard. But Im definately not the fastest guy in the world. Not the slowest, but lots of room for improvement. What can I do to improve my punching and kicking speed? Ive got a heavy bag but dont know what to do to improve in that area specifically. Im OK I guess when its only one punch, its really combos that Im lacking in. I could probably hit my bag lots faster if power was no concern whatsoever. Should I do that for a little while? If not, what?
