The session was challenging for me as one client was at a beginners level and the other more advanced. I charged them both my customary hourly fee. I understand that some trainers offer discounted prices for training 2 people together. Should I feel obligated to offer a “special rate” in order to keep these clients? I got the impression that they thought they would be getting a discounted rate.
Actually I think training two people is HARDER than training one!
Your focus is split in half and the primary client actually is giving up what they initially paid for.
I would most certainly use part of the time to assess this new person, you are as liable for their safety as you are for the primary client. After a waiver has been signed and payment has been made I would have conducted a workout with the remaining time allotted.
If you don’t want this to happen you can always put it in your contract.
