Health Science vs. Kinesiology Major - Career choices down the road?

I have been debating to become a physical therapist. But I want to hear from others what are other good career choices that stem from these two majors. I recently got admitted as a health science major and would switch to kinesiology if I am positive that I want to become a physical therapist. What jobs could branch from health science? I have no desire to go into public policy or anything involving politics + health. I love health and fitness as they are a huge part of my life due to my substance abuse past. I really appreciate any insight.
