Some of you lean guys have about 10 pounds of cock....
Gaining 10 lbs through weight training is definitely attainable. MuscleMilk and a good lifting routine should pack on lean muscle weight in no time.
Don't get me wrong, I think both Mr. Hardcock and Skinnythick look fuckin' great as they are right now, and as they get older and their metabolism changes, they will appreciate the leanness. (Trust me on this one, young 'uns.) You need look no further than Calboner's gallery to see a hot, fantastically toned lean muscle guy.
