I had another epiphany while doing the warm ups/gesture drawings; All things in nature (including lines) have movement. You can get confident strokes by drawing straight into the direction of the shape / movement. I've noticed that I have a habit of creating sketchy outlines with strokes that go back and forth, disrupting and clouding the idea of the pose and its clarity.
Sketchy strokes that go back and forth, disrupting the movement and idea - 1 minute each
Strokes that are a bit more confident and supportive... results are more fluid - 1 minute each
