This guy in my gym, he's about 6' tall, maybe 170, no mass at all, thin as a rail. He wears his headphones, gloves, gold chain, gold bracelet, and ALWAYS walks around with a big McDonald's cup like he had just finished a value meal and needs a workout to help wash it down. I've seen him there for over a year, and he's still using the same weights. He uses 20lb. dumbells when doing flat dumbbell presses and does these partial reps, and has this look on his face like he's actually lifting heavy. His partial reps are so tiny that he's barely moving his arms at all! I think he's afraid to go up in weight. Would't want to put on any mass! I always want to ask him, "what the hell are you doing with those partial reps?" The dude puts a 25lb. plate on each side of the leg press and acts like he's moving some massive weight. Atleast he's playing it smart by not lifting too heavy, but shit man, put some weight on there!!!.
