History of Gyms: How Training Became a Global Fitness Phenomenon

Greek soldiers were trained in gymnasiums from a young age, most notably the infamous Spartan warriors, who utilized the gymnasium as part of their rigorous training regimen. The legendary king of Sparta, Leonidas I, trained in a gymnasium from a young age and as a Spartan soldier in preparation for combat, which served him until he perished in the battle of Thermopylae against the overwhelming forces of the Persian Empire.

Three hundred years later, after the Roman conquest of Greece, gymnasiums continued to be used by the invaders for the training of soldiers.  Emperor Nero was the first Roman Emperor to build a gymnasium in the Roman capital of Rome, and wealthy Romans began building gymnasia attached to their homes for exercise.

The Romans adopted the concept of gymnasiums, expanding on it with the creation of bathhouses for leisure and relaxation. According to recent research, emperors such as Hadrian actively encouraged the use of gyms during their reign, helping to keep the idea of an establishment for training, exercise, and mental stimulation alive 2,500 years ago.

Unfortunately, however, after the downfall of these civilizations and the emergence of the Dark Ages, recreational physical fitness and structured exercise declined due to clashes with religion, specifically the Catholic Church. It wasn’t until the mid-to-late 1500s that the idea of gymnasiums started to gain popularity again, with writers such as Jean-Jacques Rousseau writing about the importance of structured exercise for young people.

Throughout the next two hundred years, gymnasia underwent rapid transformation, finding importance in schools, the military, and popular culture, with the first chain of multipurpose modern gyms opening as part of the Young Men’s Christian Association (YMCA) in the United States. In the 20th century, gyms continued to evolve with Jack LaLanne opening the first health club in the US and the eventual opening of Gold’s Gym in 1965, kickstarting the nation’s obsession with weightlifting and bodybuilding.

When was the Original Gold’s Gym Opened?

The original Gold’s Gym was opened in 1965 by legendary American bodybuilder Joe Gold. An avid regular of Muscle Beach in Venice, California, Gold built an indoor gym next to the beach for his friends to train in. He welded together homemade gym equipment for training, utilizing his Navy skills to design the gym’s many machines.

The gym’s barebones and gritty appeal attracted legendary bodybuilders such as Arnold Swarznigger, Franco Columbu, and Incredible Hulk actor Lou Ferrigno – kickstarting the golden era of bodybuilding.

Finding initial success, Gold later went on to sell the mythical establishment, with subsequent franchising seeing Gold’s Gym become an international brand.

To date, the Gold Gym franchise has around 700 locations globally with 3 million customers. Now owned by the RSG Group, purchased in 2020, the German fitness group looks to continue Gold’s Gym’s success by spreading its influence globally and dominating the fitness market.

From humble beginnings with homemade equipment to international success, the Gold’s Gym brand has gone through significant growth over the last 50 years since its opening by Joe Gold in 1965.
