People call themselves exercise physiologists with a BS. I tend to consider exercise physiologists having PhDs. I understand there is a MS in exercise physiology, although I myself would not call myself, or refer to a person with this higher education as an exercise physiologist. Therefore, there are different salary ranges depending on your education and experience.
What are your colleagues doing in the field? Where have they found employment? What advise did you get during your studies, as far as direction? What advise would a person with a doctorate in exercise physiology tell you? Interview them? Goggle salaries.
