you look for a guy that's absoluty georgeos sp da, and ask him to take his shirt off and i'm sure you'll be sculpting in no time, gezzz cake boss just had them on one of their repeat's they used the chocolate modeling paste, maybe u-tube might have something, they have alot of figures to make and i'll give you a bump
Try "google", put in "images" and then type in "muscles". Google will offer you several choices. I looked at men. There are several good pics. You can enlarge and print one to use as your templete. Lay the templete on a piece of parchement paper and build the muscles on top of your templete. You'll get a good rendition.
