Gesture drawings are an important part of my routine as they set the tone for the rest of the drawing session. I use them to gauge which medium I will use and what the emphasis will be for the night.

I think that gesture drawing tends to get short shrift because everyone wants to get to a finished product but I love seeing the these types of drawings from other artists because they give insight into their process. For me, the drawings are more visceral and emotional because you only have a few minutes to get the essence of the pose down. They're also just fun.
I put multiple poses on one sheet to give a sense of motion (and to save paper). 1-5 minutes.
