Couldn't think of a good title, but I'm just curious as to which muscles do not respond as well as your others do. For me it would be my Calves and Triceps... Also, I was just curious... Does your "body type" have any play in which muscles grow bigger... Ionno, was just wondering if certain muscles on an Ecto had more potential to grow or not, whilst certain muscles on a Meso have more potential to grow or not, etc.
