As a gym owner, your method and your model will likely evolve over time. Your method should be "client centric": It should be based on what your clients need. Your model is there to give clients your service in the way they want to buy it. 

At Chris Cooper's gym, Catalyst, the Prescriptive Model guides the business. The prescription changes over time to serve the exact needs of clients, and the model reflects that. 

Your method might be Pilates or yoga or CrossFit—but the "meta" model should always be prescriptive: tailored to the needs of the client. 

The Prescriptive Model helps you provide clients with 10-out-of-10 service now and evolve to keep doing that forever.
