This episode of Home Training focuses on arm strengthening. Guillaume and Sabrina start with a warm-up targeting the upper body, especially the shoulders, neck, and wrists—essential for the session. The workout engages the biceps, triceps, and deltoids with exercises that activate and stabilize the scapular chain. The second block ramps up the intensity with a cardio section to boost endurance. Every joint is carefully mobilized to ensure a smooth, injury-free session in a high-energy and motivating atmosphere.
