bz55 launches SANTORINI, a Pilates-Barre format inspired by Blue Zones

bz55 is pushing deeper into boutique fitness with SANTORINI, a 55-minute class that mixes Pilates Reformer and Barre and wraps the format in Blue Zones language about longevity. The timing matters: Barcelona is already thick with premium low-impact studios, and bz55 is trying to claim a slice of a market that rewards novelty, atmosphere, and a clear wellness identity as much as the workout itself.

The Blue Zones reference is doing real positioning work here. Blue Zones says its ideas come from more than 20 years of research into the world’s longest-lived populations, and its framework centers on habits such as moving naturally, finding purpose, managing stress, eating more plant-forward meals, and maintaining strong social ties. By borrowing that vocabulary, bz55 is signaling that SANTORINI is meant to feel like an immersive wellness experience, not just another reformer class with a prettier name.

That pitch is aimed at a very specific customer: the urban boutique buyer who wants technical training, but also wants the studio to feel aspirational. Reformer and Barre already overlap in strength, control, mobility, and aesthetics, which makes them easy to package into a premium hybrid. bz55 is betting that the class can drive motivation and adherence, two words that matter in a category where retention is often the real product.

The company is not treating SANTORINI as a one-off experiment. bz55 says its sessions are capped at 12 people and run 55 minutes, and its current studio map includes A Coruña, Ciudad Real, Valladolid, Madrid and Valencia. It is also preparing openings in Barcelona, Vigo and Gijón, with a goal of reaching 12 studios before the end of 2026. That kind of rollout suggests a standardized boutique model, not a format test.

Barcelona looks like a logical next step because the city already has a dense boutique barre and reformer scene, with operators including Be Barre Barcelona, Barrefit, Concept Barre, EDAN STUDIOS, Serotonin Studio, PILAT3S and The Barre Studio. The competition is a sign of demand, but it also raises the bar: in a market this crowded, novelty can open the door, yet premium pricing survives only if the format keeps delivering a strong identity and a reason to come back. Club Pilates Spain has also said it planned to reach 50 studios in Spain within 12 months, underscoring that reformer Pilates remains a growth segment. bz55 is entering that wave with a hybrid that is polished, specific and very aware of how crowded the room already is.
