The kBox Power Test
The kBox Power Test is our standardized protocol for testing the power of a kBox user with reliable and comparable results. The protocol is based on a 4RM squat exercise using the kMeter feedback system. Click below for a step-by-step tutorial on the test protocol:
How can you test your own or your clients’ power and get reliable numbers that can also be compared with other users and over time?
In flywheel training with the kBox, the kMeter feedback system provides accurate power monitoring, but a standardized test protocol is necessary to define in detail how the exercise should be performed and documented.
The kBox Power Test is developed so that kBox users will not need to spend time developing protocols of their own. In addition, it gives users the opportunity to share and compare results with each other. The kBox Power Test is intended for squats, but the same methodology can be applied to other exercises.
Using the kBox Power Test you also have the opportunity to submit your results to our upcoming reference database for kBox users. By sharing your data you will contribute to this flywheel training knowledge base for the benefit of your peers, and in addition, you will get an early access to the results collected.
