Hi karatekas! I'm new and I'm a girl of 17 years old, I'm green belt in shotokan style... I'm short, my height is 5,25 feet (1.60 meters) and all my karate mates are at least 1.80 meters..at least, they are all males and they are all Black belts .. :'( Now for my height no one fights against me in a serious way, they often kid me because I'm little and sick ( even if I'm sick I'have enough muscoles eh!) With this behaviour I don't learn nothing, when I was yellow belt I used to accept this because I was really a newbie, but Now I want to learn how to do a good kumite... So I want to begin a special training to improve my agility, and my explosive power, and anyone could suggest me the best techinque to defeat a boy who is the double of you? Maybe some grip o it's only a mental problem? I need a customized training PS my weight is 47 kg = 103,62 Ibs
