Where and how to get certified to instruct classes
Nikki,
I would start with one of the more nationally recognized certifications such as ACE (http://www.acefitness.org/fitness-certifications/group-fitness-certifica…) or ACSM (http://certification.acsm.org/acsm-certified-group-exercise-instructor). They are both excellent organizations, and I believe any employer would recognize their certification. This is not true with FiTour. If the recreation center is the only place you want to work and they accept FiTour you would probably want their group fitness instructor certification. That said I would encourage you to pursue a more in depth program such as from ACE or ACSM, especially if you would like to expand your teaching. I am not very comfortable with quick online programs such as Fitour.
