Good for keeping your chops up
I wouldnt say this was much of a reference tool so much as an exercise tool--they give you random poses, and if youre in the mood to just go with a pencil, its a great way to make sure youre always sketching something fresh.
And to those complaining that the anatomy is gross, I would encourage more effort towards maturity considering that knowledge of muscles is very important for any artist working in the line of living subject matter.
