ok, first of all i dont know the difference between plyometric and explosive so i would appreciate if someone explained, 2nd, I am an in-fighter so i wait for my opponent to hook or jab or anything and just slip/duck/weave/bob or w.e and take a step while doing so and get close to him, now, what drills should i do to make this step faster? like dash or something, i tried putting on 5 kg ankle weights while taking the step so it becomes faster, i also do some step jumps and squat jumps but i dont feel any difference..any help?
