In 1984, Chinyol Yi and Louis Welch founded the first LA Fitness in Covina, California. The company expanded over the next 10 years by acquiring other gyms in Southern California. In 1995, it introduced a 45,000-square-foot club design. By 1998, LA Fitness operated 36 clubs in California, Arizona, and Florida. This new model cost $6 million to build and included full-court basketball, lap pools, racquetball, saunas, and steam rooms. The company received funding from Peter Seidler to continue expanding this new concept. Additional funding was later provided by CIVC Partners.
