I used a variety of combinatiosn with the Clay buildup, standard, blob, and clay brush along with the smooth to build up the muscle tone and start defining it. Using the pinch and edge tool i was able to make the muslce tone around the neck and closer to the waist.

I spent most of my time experimenting with the anatomy of a male chest with more muscle tone apposed to the face which i have done that looks like they have been stung by a bee.
