At the age of 21, LaLanne opens his first health studio in Oakland, California. This is widely considered the first modern health club in the United States, offering weight training and nutritional guidance.

LaLanne invents numerous pieces of exercise equipment, including the weight selector, pulley machines, and leg extension machines. These inventions revolutionize the fitness industry.

LaLanne expands his business, opening health studios in other locations. He develops a franchise model, allowing others to operate studios under his name.

LaLanne sold LaLanne Fitness Centers to Bally Total Fitness in 1984.
