By charging before you are actually certified, could you be putting yourself in legal jeopardy? In my area, we are required to teach only within the limits of our certification and legally protected only when performing services specific to that training or that a reasonable person with that training would perform. Does the gym know you are charging members and do you have an agreement with them? Contractors are not covered by insurance but as staff you would be. Are you charging 1/2 price in a gym that charges for personal training? This is a sure way to get the trainers upset and possibly get you kicked out of the gym. I've seen this happen where I work. I don't want to sound negative but I wouldn't want you to be caught by surprise. Good luck and be safe. stacie
