A Complete Solution
Accurately monitoring power and energy as well as estimating force during flywheel training on the kBox, kPulley or SingleExx machines the kMeter Feedback System is used by coaches, physiotherapists and personal trainers, as well as their athletes, patients and clients.
The correctness of the data produced by the kMeter has been scientifically validated by sports scientists at Leeds Beckett University’s Carnegie School of Sport.
The kMeter consists of both software: the Exxentric App and hardware: the kMeter II, pre-installed on most Exxentric equipment and available as an add-on for the kBox4 Active.

Track Your Results
Use the Exxentric App on your mobile device to easily record your training data from any Exxentric device equipped with the kMeter.
The data recorded includes concentric and eccentric power, eccentric overload, force, energy and range of motion.
Follow your progress and share your results with your coach, physio, or personal trainer. When training a larger group, you can access the data of two clients for free, and add subscription plans to match a larger client base.

Hardware

The kMeter unit registers your training data and uploads it to the Exxentric app in real-time.
To secure accurate and reliable data, the kMeter is able to sample up to 155 revolutions per second, receiving 64 impulses per revolution of the Flywheel with a sample rate of 10,000 Hz.
The kMeter unit is battery powered for complete mobility and always on for ease of use. It can be connected to an unlimited number of mobile devices, so each user can keep track of their own development.
