Hmm...I believe that personal trainer courses and certification are typically handled by instititions outside of the typical college or university (there are other members on RJ far more knowledgable and far better qualified than myself who can inform you on this).
FIU offers degrees (B.S. and M.S.) in
Athletic Training through its College of Nursing and Health Sciences. The
curriculum seems quite vigorous, which is probably a good thing.
I recommend first getting a job in Florida and building up residency first if you intend to study there; in-state residents pay approximately 1/5 of what international students pay in tuition. Otherwise, I would strongly recommend that you look and apply for some nifty scholarships.
In other aspects, FIU has a mixed student body in terms of commuter students (students that live off-campus) and on-campus students. There is public transit that is useful, though not optimal; when driving, FIU is conveniently located in comparison to one of the major highways (the 836). I have a lot that I can say about the ups and downs of FIU...I lived there for three years (and attended FIU for a total of five years)..
