So I have always hated my arms. Because of always hovering around 180-200 lbs and due to genetics, they have always been on the large side. Even at 145, they are still bigger than I would like.
However, I am just about done with week 6 of P90X and look at my results so far:
I can now see muscles in my arms when doing simple things, like washing my hands. LOVE IT!!!!
