Health clubs are, for the personal trainer, virtual playgrounds in which to acquire and train clients. In this setting, there lies a reservoir of potential new clients as well as tremendous resources. Clubs are a great place to learn the business and establish a reputation and clientele. Employees receive training in all areas of the business, and have the benefit of working with and learning from trainers who have more experience. That's why the majority of people just beginning their personal training careers will start in this setting.
