I am interested to understand how much of the personal training market is private – where the personal trainer themselves take 90% of the fee paid by the client. And how much is generated from the gym themselves – therefore where the PT has to split the value of the session with them gym. I am interested in how this works in practice and where the PT’s would administer their private sessions.
if you are an employee at the gym, it will be part of their personal training arrangements and you would know the payment due to you per session. If you are an independent contractor, then there are different models from a flat rate to a fee per session.
For all I have seen, it matters little to the gym how you acquired the client. Even it the client was the referral to you from a friend, if he has to purchase the sessions from the gym where you work, then those conditions will apply, even though the gym has done nothing to help you get this client.
Gyms tend to look at the fee for themselves as some kind of ‘facility rental’ as they provide to you the facility and the equipment to train somebody. As Harris pointed out, the only way to get out of this is to train the client outside of a gym. But there you will have costs as well, be it rental for space or purchase of equipment unless the person has a studio at his house.
