I'm working on this at the moment and I thought I would share the progression. I start with very basic overlapping shapes and gradually I start to define it. I'm adding the muscles at the moment and will color it this week but I am waiting for my Cintiq to arrive in the mail! Very excited about it!!! Can't wait to see what it is like to use it. I was always jealous of the lead artists at the Studios I worked at. They had the Cintiqs while we regular guys had to use our Intuos 3 tablets.
