Number 37 Ferrocarril Street, in Madrid’s Delicias neighborhood, has been home for a few days now to the first club of the French gym chain On Air Fitness: a space spanning over 2,000 square meters equipped “with state-of-the-art technology and different areas designed to offer a complete fitness experience,” they explain.
In total, the space is divided into seven areas dedicated to different types of physical activity: a cardio zone, Hammer Strength (for strength training), a free weight zone and street lifting area, an exclusive glute zone, a ladies’ zone ( for women’s training and, they specify, “pink machines”), a hybrid training and weightlifting zone, and a boxing zone with a ring and MMA cage.
Beyond the sports zones, the gym also features a chill-out zone, a posing area ( surrounded by mirrors and designed for content creation), a DJ booth, and an official merchandise area. Additionally, outside the club there is “an exclusive barbershop for members.”
