Steps are much easier than that. In fact, there is only one step: put pen to paper and do not lift it until the sketch is complete. Do not draw contour lines. Draw the big shapes. Suggest movement. Easy-peasy.
The first week we had a model - dynamic poses of 3 - 5 min. She chose a sequence of about three movements (lifting a box from the floor and placing it on a shelf, that sort of thing) and repeated it for the duration of the pose.
It took me a good chunk of time only to get over the impulse of drawing the contour lines first and then be stuck there. I used pencil on newsprint, but after a while I switched to woodless graphite. The pencil lines were to thin and pale where the graphite is thicker and it slides easier over the paper. I selected a couple of sketches that represent better the requirements of the exercise.
