Slim, but fat at the same time? I have a slim appearance, but I realize I am lacking the body mass that it matters the most, bone and muscle. I have very thin arms and somewhat weak upper-body. I am 35, male, 5'10" , 152lbs. As an adult, I know it is not possible to gain bone mass. How can I improve my physique so I can maintain decent fitness level when I get older? [more inside]

What is the best way for a fairly unmotivated but still moderately fit guy with a lot of time on his hands to build upper body mass in the comfort of his own home?
