I would say tracing can help, but only if you do freehand drawings as well. trace a pose in the simplest shapes you can, look at the shapes and try to commit them to memory, and then try to draw the same pose freehand, without looking at the traced version. after one or two of those, you'll probably feel more confident, which is when you move on to only drawing freehand for the rest of that practice session to apply and add to what you've learned.
Hope this helps!
