Roei’s Studio shares client results data from 200 Barcelona clients

Roei’s Studio says data from more than 200 real Barcelona clients show fat loss of roughly 5 to 15 kilograms over 6 to 12 months, muscle gain of 3 to 7 kilograms over the same period, visible changes in about 8 to 12 weeks, and average retention above 12 months. The studio’s updated June 2026 results page turns those numbers into a direct claim: personal training should be judged by outcomes, not branding.

That retention figure is the one that matters most. In a business built on convenience and short-term motivation, keeping clients training for more than a year says the system is not just producing early wins, it is keeping people inside a routine long enough for those wins to stick.

Roei’s Studio also says about 60 percent of its clients are international residents who train in English or Spanish, which fits the city it operates in. Barcelona City Council counted 460,409 residents of foreign nationality on 1 January 2026, or 26.6 percent of the population, up from 432,556 and 25.4 percent on 1 January 2024. For a private studio trying to win trust with expatriates, relocations, and busy professionals, that is not a side note. It is the market.

The studio is based at Rocafort 118 in Eixample, near Urgell, Rocafort and Hospital Clínic, and it says clients train one-on-one in a fully private room. It also says it offers a free first session, no enrollment fee and monthly plans starting from €200. That puts Roei’s Studio in the part of Barcelona fitness where clients pay for structure, privacy and direct coaching instead of open-floor gym access.

The founder profile says Roei has a diploma from Tel Aviv University and more than nine years training clients in Barcelona. In a city where the fitness market is dense and getting denser, that experience matters. A 2026 Barcelona fitness-market report puts the city at 929 operating fitness centers, about 20 forthcoming openings at the end of 2025, roughly 733,061 members and annual business volume of about €476.3 million. Local coverage of the same market puts 81 new openings between 2020 and 2025, with boutique concepts leading the way. Roei’s Studio is betting that measurable client results are the clearest way to stand out in that crowd.
