I livw in a town on approx. 20,000 ppl in town. We have several gyms but no spinning class. There is one in a neighboring (and much smaller town) but I cant get off work intime to get there..... (enter question) I would like to in the next year or so become a spin class instructor. Whats do I need to learn / do to make this happen? I do my own thing on my trainer at home but I thought this could be a great way to earn extra $ ! Thanks in advance for any help, tips, encouragement
