just to say, if you are throwing the uppercut, my trainer said to me (i weight about 63-66), but hit hard for my weight, he said that when you throw the upper cut, use it as a shot to open the chin up for a hook. e.g. if you are orthodox chuck right uppercut, left hook/left uppercut right hook (whichever hook is more powerful) and vice verca for southpaw. That is if you ar egoing to fight, i know some weightlifting gyms fight like one round the corner from me called Cheetas. I dont know how heavy you are so youve got to decide whether it is a powershot for you. Basically try not to drop your arm when you throw the punch incase you are caught with a hook and generally be in close (when you have got them in the corner) throw short uppercuts and hooks, when at long range chuck a screwshot (basically a long uppercut that you dont lift up so far at the end, like an upside down jab).
