Hello Jamie Andrews,
Yes, absolutely. We follow a code of ethics. I have a link here for you:
NAPS 2 B Fit
FItness instructors are subject ot negligence and liability laws like many other professions. As far as I know, there are no states that require licensure. I do not think we have a specific government Occupational code, federally or on a state level. But I do not know the regs and laws of every state. You should ckeck with your local goverment to see if there regs that apply in your location.
