Description

{tab Product description}

The kMeter system consists of two parts: a wireless transmitter module connected to the kBox, and an iOS app:

kMeter Module

kMeter Module

The only thing you need beyond the app is a kMeter module, which is a bluetooth transmitter that connects to the rotational sensor under the kBox and transmits the signal to your iOS devices. The kMeter module is easily installed and is battery powered for complete mobility and ease of use. It can be connected to an unlimited number of iOS devices, so each user of a kBox can keep track of their own development. The kMeter module is compatible with all kBox models that have a sensor connector installed.

{tab Function}

3. Get the free kMeter App

  • Download the kMeter app from the Apple App Store onto your iOS device.

4. Connect the App with the Module

  • Press the on/off button on the kMeter Module (picture 2) until it starts blinking with a blue light. (It turns off automatically after a while, if not in use.)
  • Make sure that bluetooth on your iOS device is turned on, then start the kMeter app.
  • In the app, click the green Connect-button from the start screen. (Status will change from Not connected to Connected + serial number of your kMeter Module.)
  • Go through the rest of the set up process in the app and click Close.

5. Ready!

  • Start playing and work hard. Happy DOMS!

Pre reps: extra reps before the set and the data collections starts. These reps are used for acceleration and will be discarded in the workout summary. Iso mode means 0 pre-reps, usable if you want to go from a ISO-hold into dynamic action (pinch-release).

Voice: Mute or choose auditative feedback with rep count, average, peak power or power limits. Power limits allows you to set a range and kMeter will give vocal and graphic feedback if you go outside of this range.

Auto start: kMeter Module and App senses rotation and stops by itself. Acquisition of data starts and begins without any interaction for the user on the screen.

Time display: Choose between clock or timer in the screen between sets. Timer is reset after every set and is used for timing set rest.

Display results: Choose which metrics you want to see in the summary after a completed set. All metrics are saved independent of you have them displayed or not so this will not affect the data saved, only the presentation.

User data: Enter weight in kgs or lbs and height to get relative peak power in set summary (peak power in W / kg or W / lbs) and BMI.

During acquisition

Graph shows pre-reps (faded) and training reps with average or peak power values or average force for every rep. In peak power mode you get one column for CON phase (light brown) and one for ECC phase (dark brown) to track ECC overload rep by rep. With power limits activated you will see a gray area indicating that pre-set target range. Use stop to manually stop data acquisition. The rotation of the flywheel indicates motion but doesn't correlate to actual rotation speed.

You can select which numbers to show and not in setup > display results

POWER AND FORCE

  • Average power = average power for all reps in set (except pre-reps) both CON and ECC phase.
  • CONC peak power = average CON peak power during all CON phases in the set (To see CON peak for every individual rep look in graph).
  • ECC peak power = average ECC peak power during all ECC phases in the set (To see ECC peak for every individual rep look in graph).
  • Average overload % = ECC peak power / CON peak power
  • Relative peak power = W / kg or W / lbs body weight
  • Average force = Approximated force based on calculations from ROM and power. Not to be used between users or exercises but works as an approximation for certain exercises by a certain user.

MOTION

  • Range of motion = how long the the average rep was (in centimeters) over the whole set.
  • Average speed = average rep speed in m/s over the whole set.

WORKOUT

  • Generated energy = energy put into the flywheel in kJ (not your expenditure).
  • Repetitions = number of reps performed.
  • Workout time = duration of the set.
  • Inertia = the inertia you set in setup.
  • VAS = Visual analogue scale. User input after workout summary in display. Stored in database with all other data. Can be used to track effort or pain for example.
  • Press arrows up/down beside graph to switch view between average power, peak power and estimated force values.

{tab Training Exercises}







Deadlift
It could be a regular deadlift or stiff-legged deadlift. The experience of the eccentric phase in the #kBoxDeadlift will be new for most people. A nice exercise for lower back and hamstrings. Read more or watch video. #kBoxDeadlift


High pull
Can be a total body workout on the kBox thanks to the variable resistance and eccentric overload. Kick in with the legs and the eccentric phase will kick you back. Works deltoids, trapezius and arms in the regular setting and most of your upper body and core in the CLAC overload setting . Watch Video. #kBoxHighPull


Biceps curl
With the Exxentric ultra light bar, this will be your new favorite exercise. Forget giving the biceps 12 sets in the gym. The kBox will do the work in 3 maximal sets with eccentric overload. Read more or watch video. #kBoxBicepsCurl


Triceps extension / over-head press
Slow and heavy with high force development with some core strength added. Perfect for a basic exercise to build strength and power in more complex exercises. Watch video. #kBoxTricepsExtension


Bent-over row
After a couple of sets of rowing with eccentric overload you won't be able to go back to the traditional weights. It is a heavy exercise but still with a lot of power and motion, especially in the eccentric phase. It strengthens upper and lower back, shoulders and arms. Read more or watch video. #kBoxRow
