Founders’ Story
Shape Shack is born out of the desire of giving everyone access to the same athletic strength & conditioning as high level athletes. Théo went to the USA and spent a few months imprinting his mind from the high level sport culture they have. He studied and spent time in multiple gyms and mixed it up with his experience in high level sport.
Natalia, who has always wanted to create a holistic and community-oriented space, kept working out to build this type of space and created Shape Shack in 2019. Both of them tried every fitness, but they never connected with the all-cardio and over-crowded big box gym culture. They were seeking the high energy training style and the results they were used to.
After working a few years together, Théo & Natalia decided to collaborate together to create this high level environment.

Sebastien
Certifications
Passionate about anatomy and movement, I have developed – and now teach – a precise, educational approach in which nothing is left to chance. A former obese individual, sport profoundly transformed my life and shaped my vocation: to support each person, from beginner to elite athlete, in building a stronger, more resilient body, with the same level of rigor and expertise. Specialized in athletic development, resistance training, and rehabilitation-based training, I help you move pain-free through engaging sessions – because consistency is born from enjoyment.

Passionate about physical activity since childhood, I have had the opportunity to practice a wide variety of sports, both team-based and individual. Racket sports, combat sports, and ball sports have all been part of my journey. This diversity has allowed me to develop a broad and comprehensive understanding of training and human movement.
Building on this experience, I specialized in postural strengthening, functional training, physical transformation, and calisthenics. My approach focuses on effective, individualized work while respecting the body and its capabilities.
