How create human body 3d?

how create simple human body 3d use rhinoceros ??
like this :

What is the most convenient tool to do this with?
SUBD or NURBS ??

I apologize in advance for the question due to the fact that I tried to create a human figure but it didn’t work out. There are too many kinks in a person, my boats come out easier.
I also tried to find a video and repeat it, but alas, there is no such video.

Assigned to Rhino category.
