RepOne is a velocity-based training (VBT) device that uses advanced technology to measure and track the speed of barbell movements and other exercises. The device consists of a small computer unit with a wire tether that attaches to the barbell or other equipment being used. As the athlete performs the exercise, the RepOne sensor accurately measures the velocity of the movement, providing real-time feedback and data.
Key features of the RepOne VBT device include:
3D motion sensing
Automatic workout tracking
High accuracy
Real-time feedback
Daily readiness assessment
Objective performance metrics
Dynamic load adjustments
