Lou's Aerobic Fitness Center
From Futurepedia, the Back to the Future Wiki
Lou's Aerobic Fitness Center was a fitness center in 1985. The fitness center was located in the Courthouse Square of Hill Valley where Lou's Cafe used to be located. By 2015, the Cafe 80's replaced Lou's Aerobic Center.
When Marty McFly passed the center on October 25, the ladies working out inside seemed to know him. As he rides by on his skateboard and waves, the ladies inside wave back. A sign on the center advertised a year's membership for 65 dollars.
It is unknown if Lou still owns the building, but it is highly unlikely, judging by Lou's age in 1955.
