When a potential new client goes to your trainerize.me page, the only options are to purchase a program.

Having a form that the individual could fill out like a very basic consultation form will allow you to get in touch with the individual when they are considering your services.

As a potential client, only having the option of making a purchase without submiting a form to get to know the trainer would turn me away.

The only other way to do this would be through your own personal website.
