Have you ever done a job share with another personal trainer?
e.g. if you only want to work part time hours, have you ever used another trainer to provide a full time program to a client? e.g. you train the same client once per week - you see the client Mondays and s/he sees the client Wednesdays or such. Was it a success? Do you recommend it?
With so many different training styles and philosophies put forth by different trainers...I personally would not participate in a "client/job share" program.
I think it could work, but why not just schedule them specifically on days where you can train them twice per week on your own? You would have to find someone that was really on the same page as you. Anyone too ambitious will try to take the clients from you. Likewise, your client might develop a preference for the other trainer over you, or vice versa. I would avoid it unless it was the only option.
I would make sure everything is written down and the trainers discuss programming on an ongoing basis
Ultimately the client has to be 100% on board with it and has to succeed with this model.
Personally, this is not something I would do, I think it would be too conflicting.
As far as myself goes, I don't share clients with other trainers.
I have a unique client situation where I share. The other trainer is my husband, and the routines are designed to be compatible. I had been training this male client for many years, and he has a lot of challenges. We felt that a male trainer would bring a different 'feel' to the workout.
Having said that, this client situation is one-of-a-kind, and I cannot see it working easily with other scenarios.
Personal training, is very personal. You develop a bond with the client. They share and give you additional insight into what is or is not working. They may not have that same bond or develop that if they're being shuttled between different trainers.
That being said, with proper feedback between the trainers and a documentation system that supports it, it may be beneficial to the client to have a different pair of eyes and skill set work on them. For instance, I have a client who meets with me twice a week and a personal pilates instructor once a week. We often share notes and observations with the client's ok.
