kBox Training. Reduces Prostate Cancer Treatment Side-Effects.
Proven Clinical Training Protocol.
Discover how a kBox training protocol – using flywheel resistance for strength and cardio – helps men undergoing hormone therapy maintain muscle mass, boost energy, and reduce hot flashes.


Reclaiming Strength During ADT
Androgen Deprivation Therapy (ADT) is a common treatment for prostate cancer that involves suppressing the androgens that fuel cancer cell growth. While effective, it comes with side effects such as muscle loss, increased body fat, fatigue, reduced bone density, and a general decline in physical function — greatly impacting a patient’s quality of life.
Flywheel resistance training with tools like the Exxentric kBox offers a powerful, efficient, and clinically supported way to reduce these side effects. Combining a reduced footprint with a novel form of adaptive resistance, flywheel training offers meaningful muscle and strength loss prevention while maximizing accessibility and cost.

The kBox for group and clinical training applications.
-
Powerful Training Stimulus
Effective strength training helps maintain & build lean muscle mass — clinically proven to increase survivability in cancer patients. -
Adaptive Resistance
Joint-friendly resistance that automatically adjusts to individual user input to maximize accessibility and streamline group training applications. -
Optimize Space
The kBox offers a maximally efficient size-performance ratio, allowing clinics and home users to get the most out of their space. -
Evidence-Based Results
Clinically proven to help Prostate Cancer patients build muscle mass, lose fat, and improve strength and power.

Training Protocol
The training protocol that successfully built muscle mass, lost fat, and improved strength and power in patients on ADT!
ADT Side Effect
Loss of lean mass (-4%) and strength, increased fat mass +14%, insulin resistance, cardiovascular risk, depression
Pilot Study Protocol
Warm-up > Squats, Single-Arm Row > Tabata Bike Sprints 3×8
Potential Training Service & Applications
kBox training from home, use app for feedback, video workouts / online, monthly group sessions, GLP-1 blockers, Parkinson disease, knee arthrosis


Equipment Recommendations
While the original protocol used kBox + Exercise Bike, Exxentric has developed a kBox-only approach to optimize space, boost efficacy, and reduce equipment costs.
kBox-Only
Thanks to the adaptive resistance of the kBox, low intertia training can be used to replace Exercise Bikes for the cardiovascular portion of the protocol.
Equipment Recommendation
For most clinics, we suggest 6 devices training 12 patients at a time. 4 Active devices, 2 Pro devices to maximize budget while accommodating patients of all sizes and strength levels.
