They went over gesture, the importance of doing it, and some anatomy study.
Here are the three videos:
Quick Pose Gesture Sketching
Why Bother With Gesture
3 Major Masses
They are all great videos, and that site is a great resource in general.
Here are some of my attempts at 60, 45, and 30 second gestures off of posemaniacs. The very last two pictures are ones that I tried to do without any sort of reference, working with poses from my imaginations. Instagram from my phone because it is in fact lazy sunday and I did not want to edit these in photoshop, so low resolution quality. Sorry :P
