Nikki, there are many career tracks that you can take with your Masters in Exercise Science. If your interest is more in line with teaching, you could serve as an adjunct professor at a local college (I do, and enjoy this part of my career). Or, you could serve as a fitness administrator/manager involved more on the side of program design. I enjoy writing and continue to serve as an exercise and fitness writer for several publications – if writing is your ‘thing’ then I think that this is a great way to reach a wide audience with your message.
Aside from the type of work you choose, there is also a wide-variety of places where you can work. Hospitals, clinics, schools, community centers, corporate facilities etc. Lots to think about and to choose from. You’re only limited by your imagination!
