Part of this comes down to learning anatomy. An understanding of where certain landmarks are and how they are affected by weight leads to faster, more convincing drawings, and knowing what part of the body goes where and what shape/size it is means that one needs to think much less about what comes next, and more about the actual pose and the action.
As such, my drawings so far are really simple, and don't look like much.

For homework though, we're supposed to copy various master drawings and study their composition, the structure behind the pose, and various shapes of the body. Here are some of those:
