I've been taking various fitness classes for almost two years now, and several instructors have told me that I'd be great at teaching the classes myself. Upon researching various certifications, including AFAA, acefitness.org, and Zumba, I found that all the classes are very expensive. I'd love to become a teacher, however (especially in this economy) is it easy to get a job with such ceritifications, and on top of that, is it worth it?
