kBox Efficiency

The kBox flywheel training device offers important benefits of efficiency, based on a decade of experience and extensive product development.

Beyond the physiological advantages of flywheel training, these kBox benefits result in increased efficiency of training programs while lowering the total costs as compared to alternatives.


With a dozen documented exercises and many more invented by creative coaches and physiotherapists, the kBox is a truly versatile multi-purpose training device that is widely used far beyond basic squat exercises.

The cost of a pro-grade kBox system is under 1/3 of the price of a typical standard single-exercise weight stack machine.


The kBox flywheel training device is completely mobile and portable, creating multiple benefits:

  • It can be moved around inside a training facility or clinic to facilitate for varying use of limited floor space.
  • It can be easily transported in an ordinary car or checked-in when travelling by air. Also, travelling athletes could simply bring their own kBox and do the same training as they do at home, instead of adjusting to what is offered at the location they are visiting at the moment.
  • Teams can bring the device out when training in the field, or for post-activation potentiation before competitions.
  • It is easy to stove away even in small physio clinics or home gyms. For larger gyms, it can be easily alternated between flywheel group training and other programs.

This is possible since the weight of the kBox is about 15-20 kg (33-44 lbs) with one flywheel. The kBox also does not require electricity.

In comparison, squatting with traditional weights requires a barbell and 200+ kgs (500+ lbs) of weights for a strong lifter as well as rubber mats and racks for the weights.


Digital Feedback

The kBox includes an advanced rotational sensor accurately measuring your performance. With the kMeter app-based wireless feedback system this can be used to measure and save actual power output as well as estimations of several other key variables.

The kMeter is already built-in to the kBox4 Pro, kBox4 Lite and kPulley and it can be purchased for a reasonable price with the kBox4 Active. The kMeter is intuitive and easy to use for coaches and physiotherapists as well as directly by the athlete or patient.

Quick Switching

Thanks to the automatic belt adjustment of the kBox, switching between drills and users is quick and hassle-free. Moreover, changing the resistance in terms of inertia requires only a quick shift of light flywheels, weighing only a couple of kgs each.

This creates important efficiency advantages in team sports and group training programmes as well as for the individual trainee. You spend more time working out instead of shifting weight plates back and forth.

Silent Work

The kBox practically doesn’t emit any sound at all. There is only a low hum from the belt, and you can hear when the flywheel changes direction. But you will certainly be louder in comparison.

Hence, there is no need for noise reducing measures such as rubber mats or noise reducing plates. It is easy to communicate with the subject performing the exercises. And it can be used anywhere, even in your living room.


In summary, the benefits of the kBox boil down to the possibility of more efficient and effective training programs, at a lower total cost than traditional purely weight-based alternatives.
