Serotonin Studio opens second Barcelona club with premium fitness model

Serotonin Studio’s new club in Les Corts asks a bigger question than a single opening: can Barcelona support a neighborhood micro-chain built on premium service, not just one glossy flagship? The answer, so far, is being tested at avenida de Josep Tarradellas 91, where the operator has turned a second address into a repeatable business case rather than a one-off statement piece.

The new space covers 400 square meters and is designed around a broader training mix than a conventional gym. Members will find strength work, Pilates Reformer, yoga, barre, TRX and functional training under one roof, spread across four separate rooms. The studio plans to run 12 to 14 classes a day, with group sizes tailored to each discipline instead of a single mass-market floor plan.

Les Corts was chosen for more than its foot traffic. The opening fits Serotonin’s premium positioning in one of Barcelona’s higher-spending wellness corridors, where customers are buying atmosphere, coaching and consistency as much as access to equipment. The company’s model leans heavily on small groups, hands-on instruction, design, music, emotional wellbeing and community, all meant to build stronger loyalty than a low-cost membership product can usually deliver.

That positioning came with a meaningful price tag. Serotonin said the project required an investment of close to 300,000 euros, mainly for adapting the premises, buying equipment, fitting out changing rooms and covering the early operational ramp-up. The company is not chasing growth for its own sake. It wants a business that is profitable, sustainable and aligned with the experience it promises, a message that matters in a city where boutique fitness is becoming more crowded and more sophisticated.

The first Serotonin center has already given the brand proof of concept. It reached monthly break-even in six months and recovered the original investment in its fourth year, a timeline that suggests disciplined unit economics rather than speculative expansion. The new club also brings in Lucía Romero as a shareholder after she started as a trainer, a move Serotonin presents as part of its effort to develop talent from within and preserve continuity as it grows.

Taken together, the second Barcelona site looks less like a leap of faith than a blueprint. If Les Corts performs, Serotonin will have shown that premium boutique fitness in Barcelona can support a neighborhood-scale chain, with the economics, staffing model and customer profile to expand into other affluent districts.
