I work in a pharma company and it comes up every time a marketing person comes to a science meeting in a particular department. The short version is that it's very very hard, even if we can profile all of the changes during exercise (which we can't), you can't just use that to know what to administer to someone.
At that point it sounds like it would be easier to jab an electrode in your neck matrix-style and have your body go through a programmed exercise while you watch a movie or something.
