MENOMONEE FALLS, WI (Ben Caxton) — Kohl’s, which is on a mission to shrink its biggest department stores, said it will lease or sell the newly empty space at 10 locations to Planet Fitness, but may increase that number in the future. The new neighbor won’t share doors with Kohl’s, but it hopes that those who frequent Planet Fitness will also stop at Kohl’s to buy fitness trackers, workout tights or sneakers. The companies plan to promote each other to their customers. The company has a similar deal with no-frills German grocer, Aldi, opening the grocery stores next door to Kohl’s. Planet Fitness said its Kohl’s-adjacent gyms will be between 20,000 square feet and 25,000 square feet. Menomonee Falls, Wisconsin-based Kohl’s, has more than 1,100 stores nationwide.
