Mike Said:

which adult courses can one take to pursue a career in fitness/health?

We Answered:

If you mean exercise, certificate, that's it. There are certifications depending on what you want to do. Google fitness/health.
Otherwise, fitness/health is a pretty broad category. Doctor, nurse, physical therapist? They are in this category.
