What comes together when attempting to draw a foreshortened figure are principles of depth/perspective and knowledge of the human form.
Pic related, a foreshortened form, as the term suggests, will never be as long as in straight on view.
If you think of the human body as made up of thin plates stacked onto each other, as a 3d printer would, and you tilt the figure in space, these plates would overlap each other.
Some may be hidden or only peek out a bit.
When you know about the volume or form of the body and about how forms diminish in size when they recede into space, you can estimate how the plates or forms would overlap.
When drawing a foreshortened figure, there is a temptation to draw parts that wouldn't be visible from the intended view, because the actual two-dimensional shape does not correspond with what we are familiar with as the human form, which is an image gathered mostly from straight-on views.
So you have to submit to drawing shapes that may seem abstract at first.
Through practice like observing and drawing from life (simplify the forms, eg. arm=cylinder) you can be able to recognize reoccurring shapes and get a feel for what looks right, even from unusual angles.

tl;dr: learn about perspective principles and anatomy, draw from life
