KINETIC LAB-Link runs in your smartphone browser — no app installation required. Please have the following ready before you begin.
Included in the box: the dedicated sensor, Quick Start Guide, User Manual, and B-TUBE (2× size S, 2× size M).
Initial registration requires a Google account or an Apple account. It takes just three steps.
Finally, enter the activation code delivered by email to complete registration.
The activation code is sent separately by email after you order online. It is delivered to the email address used for your order.
If you don't have an AI coaching code yet, please purchase one from the KINETIC LAB STORE and then register.
No. The activation code is required for initial registration, and AI coaching cannot be used without it. The code-entry step cannot be skipped.
If you don't have a code, purchase AI coaching from the KINETIC LAB STORE and a code will be issued to you by email.
Once you enter the code, you can carry over your past measurement data.
Connect the dedicated sensor and the external battery with a USB-C cable. When the sensor's LCD screen lights up, it is ready to measure.
Thread a rubber band through the slits on the top and bottom sides of the unit to secure the external battery to the back or bottom of the sensor. This keeps the battery from dangling during measurement so you can measure steadily.
Before you start measuring, please check the following two things.
Measurement takes some time. Don't rush — operate slowly and calmly.
You measure 5 points on each side — 10 in total. Measure from the top of the body (the head) downward, in the order 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9 → 10.
The 5 measurement points (scalene muscle / lateral chest / anatomical snuffbox / patellar ligament / behind the medial malleolus) have exact locations on the body. Please see the detailed illustrated guide.
▶ Body Scan Measurement Guide (the 5 points explained with illustrations)
Place the silver tip of the sensor gently into the hollow at each measurement point. There is no need to press hard.
Measure behind the sternocleidomastoid muscle (the posterior triangle of the neck), in the hollow just above the collarbone. The hollow just above the collarbone, on the side of the neck, is your landmark.
Measure under the arm, at the middle of the side of the ribcage, slightly above the line connecting the left and right nipples.
Measure the hollow that forms on the thumb side of the wrist when you gently spread your thumb. This hollow is the "anatomical snuffbox."
Measure the ligament just below the patella (kneecap) that runs to the shinbone. The cord-like part below the kneecap is your landmark.
Measure behind the inner ankle bone (medial malleolus), in the hollow between it and the Achilles tendon.
▶ See the location behind the medial malleolus with illustrations
By the nature of the sensor, the surface condition of your skin (moisture, oils, chemicals) can cause measurement errors or fluctuating data. Always check the following before measuring.
No. Sweat on the skin prevents an accurate reading. Always wipe sweat completely off with a dry towel or paper at the measurement area before measuring.
In extremely dry regions or environments, measurement may fail to start or error out with the default settings.
At a spot with a prosthetic limb or cast, press the "Reset" button on the sensor screen, then select/confirm "Set to 0" before continuing to measure.
After measuring, use "QR scan" in the browser where you are logged in to AI coaching to read the QR code shown on the sensor's LCD. Once the scan completes, your measurement data is sent to AI coaching.
Scanning the QR code requires that your smartphone is connected to the internet and that you are logged in to AI coaching. Then check the following.
The Score expresses, as a number, how well the day's natural environment (season, moon phase, etc.) matches your body's condition that day. A higher number means your body is more in sync with the natural environment.
The 3D body model shown on Home and in "Today's exercise & breathing guidance" is greatly exaggerated to make the tendencies of your body's imbalance easy to see. It does not mean your actual body looks exactly like this.
All of them are shown on the AI coaching Home.
Open "History" in the AI coaching bottom menu to see the daily Score and its trend.
For the 10-day / 30-day / 180-day analysis, use the "Analyze your progress so far" button under "Progress so far" at the bottom of Home.
We recommend measuring and doing the breathing method every day. Home → "Streak" shows your consecutive days and total count. Skipping days is not a problem — once you resume, it is reflected in your streak.
There is no set time of day. Choose a time when you can measure calmly, with sweat wiped off and no sunscreen, antiperspirant or cream on the skin (see "Is there any preparation for accurate measurement?").
If several people share one account, everyone's body-balance data and measurement results get mixed into a single history, and the AI can no longer recognize your true condition. This leads to incorrect analysis and inappropriate exercise recommendations.
Based on your measurement data, you receive body-balance analysis plus advice and exercise suggestions tailored to your condition. You can also consult it about physical concerns or improving your performance.
AI advice is an AI coach that advises you, based on the BC Total Balance System, while referring to your measurement results and today's condition.

Take the pose shown on the AI-coaching screen. Pay attention to these three points:
See the videos below for the posture points and a demonstration.
This is not an instruction about your posture during measurement. It is the pose instruction for the breathing method and exercise, shown in steps ① and ③ of "Today's exercise and breathing guidance" after your measurement.
When you take a pose like this, first settle into the pose shown on the body model, then hold still for about 15 seconds and feel your body.
Trying to spread your fingers puts tension into the palm. Focus on letting the palm itself, not the fingers, spread out freely.
The same goes for the feet: trying to spread the toes tenses the sole, so focus on letting the sole itself, not the toes, spread out freely.
The B-TUBE (dedicated tube) comes in three sizes: S, M and L (S×2 and M×2 are included). The size to use each day is shown on the AI coaching Home under "Today's breathing" — follow that instruction.
▶ Breathing guide (main video and explanatory videos)
Additional B-TUBEs are available at the KINETIC LAB STORE.
5 sets (one inhale + one exhale = one set) as the standard.
The number of repetitions does not change with the B-TUBE size (S / M). The same 5 sets are the standard for both.
It varies from person to person, but an inhale takes roughly 9 to 12 seconds. Inhale strongly so that the air reaches the bottom of your abdomen.
You may breathe out through the nose or the mouth — either is fine. Inhaling is the goal, so do not think about how long you exhale; just breathe out comfortably.
Is the timing the same for S and M: because S is the narrower tube, the inhale tends to take longer. For either size, inhale strongly so the air reaches the bottom of your abdomen.
Trying to spread your fingers puts tension into the palm. Focus on letting the palm itself, not the fingers, spread out freely.
The same goes for the feet: trying to spread the toes tenses the sole, so focus on letting the sole itself, not the toes, spread out freely.
The gel or balm is applied after the breathing method to the "gel points" on your own body. Your own gel points are displayed in red in the AI coaching (application). Take the gel in your hand and apply it to the red areas shown.
Replacement gel is available at the KINETIC LAB STORE.
Before the breathing method and gel, check which side of your body is "harder" (so you can compare afterwards).
First, if you have symptoms of your own — for example a sore shoulder — check the condition of that area.
If you have no such symptoms, the pose shown in the AI coaching (application) is the one that is harder for you. Check the neck and face direction, the palms, and the feet front-back and left-right differences, then identify which side is harder and which side is easier.
This is not a check that the measurement is complete. After finishing the whole sequence — the breathing method, applying the gel, and so on — check the neck and face direction, the palms, and the feet front-back and left-right differences once more and compare with the "harder side" you found before.
Stop immediately and do not push through. Do not repeat the movement or pose that caused pain that day, and rest until you feel settled.
As a benefit for KINETIC LAB-Link users, we stream the "Kinetic Academy" seminars on the web. You can watch the sessions from home or anywhere else.
Open "Live" in the AI coaching bottom menu and see the "Event calendar". Because streams are irregular, each one is posted there — with the date, time and viewing URL — once it is scheduled. Please check it before the event.
New streams are also announced under "Notices from support" on Home.
The streaming platform is YouTube. To watch:
Past streams may be available under "Event archive" in "Live" (not every session is kept).
For comfortable viewing, please prepare your own viewing environment. The following are not guaranteed or covered by us.
In short: start/end times and publication times may shift, and the video or audio may be disrupted or the stream interrupted or cancelled due to line, system, or other unforeseen trouble. We cannot accept liability for any resulting disadvantage or damage.
The official disclaimer is shown below in the original Japanese.
To prevent crowding and trouble, please refrain from coming to the venue. If you wish to attend a seminar in person in the future, you must apply in advance — walk-in participation is not accepted. For the steps and details, please check the page linked below.
The official notice is shown below in the original Japanese.
The B-TUBE can be purchased from the KINETIC LAB STORE.
If you purchased the dedicated sensor, 2 × size S and 2 × size M are included in the box. Please check the included B-TUBEs first.
For choosing a size see "How do I choose the B-TUBE size (S / M / L)?"; for how to use it see the breathing guide.
The B-TUBE comes in three sizes: S, M and L. The size to use each day is shown on the AI coaching Home under "Today's breathing" — follow that display rather than deciding yourself (it is not chosen by body size).
As a guide, size S is used more often when the moon is a "waxing moon" (bright on the right), and size M when it is a "waning moon" (bright on the left).
Size L is used for breathing training while playing sports and for people with weak breathing (not included in the box).
Additional B-TUBE can be purchased from the KINETIC LAB STORE.
Yes. The dedicated gel (oil) and consumables (replacement sensor heads, extra B-TUBEs, etc.) can be re-ordered from the KINETIC LAB STORE.
The dedicated gel is not included with the sensor (the box contains the dedicated sensor, quick start guide, user manual and B-TUBE S×2 / M×2). Please purchase the gel separately from the STORE.
Plan changes are not accepted. Please review your contract details for more information.
