Well I need a lot of mobility for throws and twisting out of them in the air. So I need to stay as light as possible with as much power and agility as I can. Mobility also helps me to get out of armbars without breaking my arm off lol I still need to get back in competition shape though (far from it right now). I'll probably look into crossfit before and then maybe do a bit of power lifting (more for my legs than anything, since they help tremendously for throws)
