In 1976, Joe Gold founded World Gym International during the heyday of Muscle Beach in Venice Beach, California.

World Gym is where iron men like Schwarzenegger and Lou Ferrigno worked out on the regular.

This week, we interview Jarrod Saracco, World Gym's COO. He is a 25-year veteran of the health and fitness industry with experience at every level of club operations.

We discuss:

• The history of World Gym

• What he anticipates the future of World Gym will look like

• Key essentials for running a successful gym or club

• What to know about gym equipment before you stock your gym

• Why gym design and member experience are more important than you think

World's Gym owners are projecting that the brand will grow to 500 locations by 2023.
