Strong Innovations That Marked Our First Decade
\'
Exxentric foundation & kBox Launch
Friends and co-founders of Exxentric, Fredrik Correa and Mårten Fredriksson, developed their next-generation flywheel device, the kBox. The device would soon expand to over 14 countries, with professional sports teams showing immediate interest in the flywheel device, making the kBox an essential part of their training sessions.
kBox2 launch
The second-generation kBox spread fastly across Europe, Asia, and America. Sports Leagues made the kBox2 part of their training to maximize muscle hypertrophy, and for injury prevention too.
kBox3 launch
The kBox3 was designed to offer safer overload at higher speeds. The improved kBox3 version, launched in 2015, included tracking software & a real-time feedback system.
kBox4 Pro & kBox4 Lite launch
Now in its fourth generation, the kBox family expanded with two new models: the kBox Pro, offering the largest performance area, and the kBox4 Lite, the lightest kBox model, practical to pack and travel with.
kBox4 Active launch
The latest kBox4 model, the kBox4 Active was a robust entry-level device that came with a more ergonomic structure, increased portability, and a smaller footprint.
kPulley launch
Inspired by the creative usage of the kBox, the next flywheel training device would be a versatile training solution, optimized for over 30 horizontal exercises: the kPulley. Soon after its release, a second-generation device, the kPulley2 would be launched in 2019.
legExx launch
In a quest to build the best leg extension device ever, in 2020 we finalized the LegExx, optimized for leg extension training sessions, with variable resistance, and eccentric loading capacity.
