I am an aspiring fitness instructor and currently am weighing options such as going back to school for a Masters, going to a community college for an Associate, going to a school such as Lifetime Academy, or attempting a combination of self-education, apprenticeship, internship, conferences, online courses, etc. In any case, I’d like to self-study a bit beforehand. What are considered the best science-based kinesiology textbooks in the industry?

Secondly, has anyone gone through a Master’s program in Kinesiology when their undergrad and/or previous graduate degrees were completely unrelated? What would you recommend to prepare?
