I wish you luck. I am personally not pro online training. Not a supporter of exercise videos or other types of training without a person actually there to observe in real time from all angles. And especially in the event of an emergency arising. But I am old and old school in too many ways. Remote check ins and motivation? I am all for them. I would recommend you finding out how you can contact 911 from your location for the client’s location. As to liability issues, I am not sure how that would play out. But I would look into that as well before I attempted training someone who was not in actually with me. And I am sure a number of people will give me a thumb down for this. Please feel free to do so. I hope that I am just being overly cautious. And no ever gets harmed in anyway while participating in online training. I would love to be wrong about my position on this.
