What is the job description of exercise science?

This degree is most useful if one is going to coach at the college level, or going into a Masters or PT program, but you can work in a health club, as a recreation programmer at a park district or youth home typically. I recommend getting Licensed to teach P.E. in addition to Majoring in Ex Sci. In most cases, that is just a matter of adding some Education theory and curriculum classes and student teaching.
