staying light and grappling
is it possible to train in grappling and remain light and fast without being dominated by heavier guys. ultimately i want to stay in prime physical condition, is this possible while being thrown around on the mats and training with larger fighters? how important is lower body strength compared to upper body strength, and which is more important in grappling? i would rather put 10 pounds of muscles onto my legs than 5 pounds of fat onto my gut just to compete, is it worth putting time, money and energy into expanding my fighting skills or is staying lean and clean with toned muscle mass impossible when involving yourself in wrestling or ground fighting?
