17) You probably noticed the open ended loop resulting in a 5 sided poly. Since I'm not planning on adding any detail to this part of the arm later I'll make it all into quads now. I do this by adding some edges and removing others, causing a redirection of the flow of edges

18) Lets add in some more edges for the elbow and more forearm muscles

19) And even more edges together with a slight change of loop direction. The loops end in two open edges halfway across the forearm but should not cause any problems. I didn't want to add more loops to fix this but if it causes any problems it's easy enough to find a place to get rid of them once the hands are attached.

20) Which is what we'll do now! Go to the hand tutorial to see how I built it

21) With the arm done we'll continue on the back. To define the shoulder blades we add some more edges (2) and move the verts around (3)

22) Some of the new edges created in step 21 will serve to round out the butt as well
