Im with the rest of the fellas try boxing, i have done both stand up fighting (muay thai) and power lifting, both are good but the boxing is somthing that later on in life you might not have the time to do,wt lifting can be done in any gym, plus though you wont be able to lift as much i bet youl be able to still lift 3 or maybe 4 times a week, just find a good trainer and talk to him about what your doing. I have two great trainers that have set up programs that alway me to do both, i lift 4times a week and work on my stand up skills 3 times a week,, not going to make me a pro but it works pretty well fo me.
