Stwar Serrano

From Holguín, Cuba, to becoming one of the most respected martial arts instructors in the Baix Llobregat region, Stwar Serrano has walked a path defined by discipline, determination, and excellence. His journey began on the Caribbean island, where he forged the foundation of his career as an elite athlete, before bringing his talent to Europe, establishing himself in Barcelona as a professional fighter and training under the Gracie Barra methodology. Today, after more than 2 years as an instructor at Ryutai Viladecans, Stwar passes on to his students the real-world experience that only a high-level competitor can offer.

With 7 years as a professional MMA fighter and 9 bouts in international organizations (AFL, WFT, GFA, Almogavers), Stwar doesn't teach theory—he teaches what he's lived inside the cage. Champion of Cuba in Kickboxing (WAKO 2010), Amateur Boxing Champion of Catalonia, and MMA Champion in France (FBA), his record speaks of international consistency and adaptability. His wins include submission victories (rear-naked choke) that demonstrate his technical mastery in both striking and grappling. This real experience in high-level competition is what sets his classes apart: every technique taught has been tested under pressure, every strategy comes from actual hours in combat.

As a Brazilian Jiu-Jitsu Black Belt graduated from Gracie Barra, one of the world's most prestigious academies, Stwar brings technical rigor and proven methodology to his BJJ and MMA classes in Viladecans. At Ryutai, he implements the certified methodology of <a href="https://foxjiujitsuacademy.com/" target="_blank" rel="noopener noreferrer">Fox Jiu Jitsu Academy</a>, internationally recognized for its structured teaching system. His affiliation with MMA Barcelona Team and Gracie Barra Barcelona keeps him connected to the highest teaching standards. Specialized in grappling, submissions, and striking, his approach combines the technical precision of Brazilian Jiu-Jitsu with the tactical effectiveness of modern MMA. At Ryutai Viladecans, he works with students of all levels: from beginners who have never stepped on a mat to competitors looking to refine their game. Located in the heart of Baix Llobregat, the gym is easily accessible from Sant Boi de Llobregat, Gavà, El Prat de Llobregat and Barcelona Airport (just 10 minutes by car), with parking available at both locations.

Beyond the mat, Stwar is the founder of Duracco (duracco.com), a sportswear brand that reflects the same values he preaches in his training sessions: discipline, determination, and excellence. This entrepreneurial vision complements his philosophy as an instructor: it's not just about learning techniques, but developing a fighter's mindset applicable to all aspects of life. Training with Stwar means learning from someone who has been at the top of international competition and now channels that experience to transform his students, whether you're seeking self-defense, getting in shape, or competing professionally.
