RE: Weight routine for a kickboxer?
youve got two slightly contadictory arts there in terms of training. dont get me wrong, they compliment each other very well from a SD point of view but youre looking for slightly different things from each in terms of what you're asking your body to do.
what condition are you in now? what are your strengths and weaknesses in terms of physical strength, stamina, speed in the ring, flexibility, reflexes etc? eg if youre already quite a big guy, say, it might be best to work on fitness and flexibility as your weight brings with it a degree of power?
if youre just starting out in weighlifting you cant go too far wrong whatever you do but i would suggest more like a powerlifting routine, and just go for strength. the training you get at your clubs will give you all of the rest and some extra strength will be handy on the deck.
