I'm mates with a lot of guys who do it, you finish the degree with the title 'exercise physiologist'.
From second year onwards your doing all subjects from the school of medical sciences, so- physiology, anatomy, pharmacology, histology, pathology. Then in 3rd year I think there are some compulsory subjects you must do like 'sports and exercise physiology' but then you still get a choice within the medical sciences of what you want to major / specialize in.
i was considering doing B health and exercise science, but when i looked at the later year subs, i was like 'nope, just finish my science degree'. Mainly b'cause i am into the 'exercise/fitness/health' thing..
