double-unders (for foot speed and quickness), box jumps, footwork drills, starting drills (off the blocks), overspeed training, parachute training, etc..
there are a lot of things you can do...
why do you want to improve it? for track or for fun?
Sorry for the thread-jack, but DUs are a pet peeve of mine. DUs are absolutely the wrong place to start. In fact, the way most people do them, it doesn't train foot speed at all. CF has screwed up the general understanding of jump rope training as bad as they have medicine ball training.
