Exxentric

Exxentric is a performance-training and sports technology company specializing in flywheel resistance training systems that enable users to develop strength, power, speed, and rehabilitation outcomes with unique variable resistance. Their flagship product, the kBox, uses a rotating flywheel to create concentric and eccentric loading through inertia rather than traditional weights, allowing athletes, teams, clinics, and performance facilities to train with precise control of eccentric overload and velocity-dependent resistance. Exxentric combines science-backed exercise concepts with durable hardware and intuitive software, making their equipment suitable for elite sports performance, injury prevention and rehab, and general strength development. The brand emphasizes innovative training technology, real-time feedback, and adaptable programming to help users train more efficiently and safely across a variety of athletic and therapeutic applications.
