Yuri Sakovich has a new tutorial online at CGArena about a new model made using Zbrush.

Modeling was very simple. I based my model off the original sketch and created what is known as an organized mesh. Meaning, that the topology of the model is in accordance to the muscle structure. Once that was done, I made sure to set the scale to my liking and imported into ZBrush to check it.
