1980’s-themed fitness chain Retrofitness is making Atlanta debut, part of a strategy to spread south and west from its East Coast roots. The New Jersey-based fitness club franchisor said it will open a 14,200 square-foot club in Smyrna by March. The company also says it has signed commitments to open two corporate locations in Buckhead and Sandy Springs. The company plans to convert all three locations into franchises when they are up and running. Retrofitness wants to open 15 to 20 locations in the Atlanta market within 24 months. Retrofitness says it aims for an "exciting ’80s atmosphere" with retro color schemes, classic ’80s music and theaters that show film classics like "Ferris Bueller’s Day Off" on screens up to 20 feet wide for customers doing their cardiovascular workouts. The $19.99 monthly membership rate is "guaranteed to never increase," the company said.
