HOW CAN I MAKE MORE BODY MASS AND MUSCLES ? ? ?

I wouldn't have thought bodybuilding would be something as boxer would be interested in, cos its all show isnt' it? oyu have huge muscles and weigh a ton but aren't actualy that strong? So what are the things you need outside the gym that everyone keeps mentioning?

lol ofc working out with weights help as long as you can handle a good regime mixed with it thats what i think at least look at bob sapp his a weight lifter (like to bring him up ) he smashes his opponents to the ground . muscels are important .
