Gap years and draft deferment

If the draft is reinstated, I wonder how they will handle the fact that most of the draftees are not fit enough for the military. This is currently a huge problem for military recruiters. People who want to join the military are turned away because they don’t meet the fitness requirements (or are unable to meet these requirements after a time of fitness training). What will the military do with a huge group of unfit draftees.

That said, I doubt that the draft will be reinstated.
