Martínez Campos, the second chapter of B3B
In 2019 we opened the second B3B in the very heart of Chamberí, just steps from Museo Sorolla, Glorieta de Rubén Darío and Paseo de la Castellana, in one of Madrid's most elegant neighbourhoods. A space with two spacious training rooms fully equipped for every level. We offer full changing rooms, towels, hair straighteners, hairdryers and parking nearby.
B3B Power
50 min combining strength, boxing and barre. Power, coordination and endurance in a session that blends individual and group energy. One of the most complete in the studio.
“I feel my body is more toned, and I’m increasingly able to lift heavier weights.”
B3B Original
B3B Barre
50 min combining ballet, fitness pilates and yoga. Strength and endurance training, stretching, and postural work to reduce stress and build a stronger, more balanced body.
“I love the barre class. It really helps with my posture. You guys are great!”
B3B Strength
50 minutes of weights with cardio intervals. This workout is designed to help you build strength from day one while prioritizing proper technique, safety, and long-term results.
“They challenged me to use 4, 6, and 8-kilo weights, which was something I thought was impossible.”

B3B Salamanca
The very first B3B, set in the heart of the Salamanca district, one of Madrid's most premium neighbourhoods. Just steps from Mercado de la Paz, Calle Velázquez and the lively terraces of Recoletos, Ayala holds the origin of the method and the energy of the very first B3B lovers. We offer full changing rooms, towels, hair straighteners, hairdryers and parking nearby.
B3B Chamartín
Our third studio opened in the heart of Chamartín, just steps from the Bernabéu and Plaza de Castilla, one of Madrid's most active and vibrant areas. Here our workouts live across three distinct training spaces, connected by an open-plan interior designed with care down to the last detail. We offer full changing rooms, towels, hair straighteners, hairdryers and parking nearby.
B3B Retiro
Our fifth studio opened in the very heart of the Ibiza neighbourhood, just steps from the iconic Retiro park and Calle Narváez, in one of the greenest and liveliest areas of Madrid. A space designed for training hard without ever losing your calm, with the city's most emblematic park just a few metres away. We offer full changing rooms, towels, hair straighteners, hairdryers and parking nearby.
B3B Eixample
In 2024 we opened our fourth studio in Barcelona, in the very heart of the Eixample, right beside Passeig de Gràcia and the modernist buildings of Roger de Llúria. A meeting point for B3B lovers in a unique enclave of architecture and design — the perfect place to train and then stay for a bite to eat or a stroll. We offer full changing rooms, towels, hair straighteners, hairdryers and parking nearby.
