This is equivalent to students using AI to complete computer programming assignments. They misconstrue the purpose of an assignment as just one of generating output instead something to teach the principles and techniques they'll require later if they want a job in the profession. While they may believe they're fooling the teacher, all they're really doing is fooling, and cheating, themselves.

Whether it be writing or computer programming, or exercising, for that matter, if you aren't willing to put in the work to achieve your goals, why bother?
