Business Model and How It Works BEFmodel allows clients to train with a personal trainer 2 to 3x/week for one hour at a typical monthly cost of $199-$250. Clients share trainers with up to 4 to 6 other clients during their one hour session. After a typical 10 minute warm up period, (during which time the assigned trainer checks the client's chart and formulates a workout plan), the trainer demonstrates a series of two or three exercises that form the first training circuit. Clients will typically complete this circuit three times. In the interim, the trainer is helping other clients. After a client's circuit is completed, a different one is assigned by the trainer. With this approach, trainers can focus on a given client who may need extra help or demonstration or supervision.
