Food and getting big
Don't even try to tell me you don't eat a good breakfast and can't figure out why your muscle mass is staying the same. Do you want to slam it harder, last longer? EAT!!! EAT!!! EAT!!! When I competed in the Mr. Universe I was eating 8,000 calories per day of clean food (I.e., no fats, sugars or salts). Eat food!!! And you'll be able to do a whole lot more.
