Answer 1

Go to the gym, and ask the guys there about your question.

Answer 2

curls, & tricept extensions will increase your muscle size

Answer 3

MIx it up a bit... but here are two of my favourites....

Do your bicep curls using dumbells.. seated.. one arm at a time... and twist your wrist at the top of the curl so that your nuckles point away from you. (You will really feel that twist at the top on your biceps)

Do your tricep cable pushdowns with reverse grip that is.. with nuckles facing away from you... full range of motion until your elbows hyper-extend. (You will really feel the load on your triceps at the bottom of the press)
