The Kynett STREXBOX is a NEW compact versatile flywheel training system designed for professionals, athletes and home users.
Flywheel training is known for its ability to generate adaptive resistance and eccentric overload, making it highly effective for strength development, injury prevention, and rehabilitation.
The STREXBOX brings these principles into a compact and portable system that can easily be integrated into all training environments. Flywheel training has proven benefits for strength development, injury prevention and rehabilitation. Its compact design makes the system easy to place, store, and use, while still delivering the training stimulus expected from professional flywheel resistance training.
