I recently had this conversation as I have just opened my training facility to the public.
A lot of you are saying basically the same things I said. "No one I train will sue me because...<insert reason here>" and you are probably correct, just as I assumed I was. The problem is NOT the students, it is the student's insurance company. If they get hurt and file a claim through their insurance company because they had to go to the hospital, guess who the insurance company is going to come after? It's no different if you wreck your car. Your insurance will cover it NP, but they're going to go after the other guys insurance company...
Was certainly something to think about when it was brought to my attention.
