Let’s get started.
1. Setting Up Suji for Upper or Lower Body
Suji is simple to set up once calibration has been completed during your onboarding. The steps below cover how to connect, position the cuffs, and start your session. If you haven’t already, you can watch the quick setup video here.
Upper Body Setup
- Connect Suji to the compression garment by aligning the circular magnets on the cuff and on the device, and pushing them together until you hear a small click.
-
Place the arm cuff as high on the arm as possible, just below the shoulder, ensuring it sits flat and comfortably.
** If fastening the cuff with one hand is difficult, first wrap it around your arm to find the correct size using the sizing lines inside the cuff — similar to a measuring tape. Then, take the cuff off, use both hands to fasten it at that size, and slide the secured cuff up to the top of your limb. For a quick video showing this process click here. -
Turn the devices on – the app will automatically connect to your Sujis.
** If the devices don’t auto-connect, a pairing prompt will appear. (Follow the on-screen instructions to pair the devices for easier connection in future sessions.) You can confirm a stable Bluetooth connection if the LED lights are solid white. If they are flashing, a Bluetooth connection was not successful. If the lights are not on, the device is off. Do not connect your Suji devices via Bluetooth outside of the app as this may result in a faulty connection. You can find more information here on our FAQ's page. -
In the app, select an Upper Body program.
-
Continue with your program once Suji is securely fastened to the top most portion of your limb and the devices are connected.
Lower Body Setup
-
Connect Suji to the compression garment.
-
Place the leg cuff as high on the thigh as possible, close to the hip crease, making sure it’s snug and flat.
-
Turn the devices on – the app will automatically connect to your Sujis.
** If the devices don’t auto-connect, a pairing prompt will appear. (Follow the on-screen instructions to pair the devices for easier connection in future sessions.) You can confirm a stable Bluetooth connection if the LED lights are solid white. If they are flashing, a Bluetooth connection was not successful. If the lights are not on, the device is off. Do not connect your Suji devices via Bluetooth outside of the app as this may result in a faulty connection. You can find more information here on our FAQ's page.
-
In the app, select a Lower Body program.
-
Continue with your program once Suji is securely fastened to the top most portion of your limb and the devices are connected.
Note: During onboarding, if you did not calibrate your leg you’ll be unable to use Suji on the lower body. Similarly, if you did not calibrate your arm you will be unable to complete upper body sessions.
2. Understanding Suji Programs
Suji offers four types of training and recovery programs — each designed with a specific outcome in mind. Here’s what they do and when to use them.
Immediate Relief – Single Session
Best for: Pain relief, warmups, cooldowns, and quick muscle activation.
What it does:
Manipulates blood flow during very low intensity, continuous movement or exercise to increase circulation and trigger a systemic endorphin rush. These naturally occurring endorphins flood the body, significantly reducing joint pain sensitivity and stiffness. Remove Suji, and move freely with less discomfort for 2 to 24 hours.
Use when:
You feel stiff or sore before exercise or sleep and need rapid relief.
No commitment — just choose the session and go. It takes less than 10 minutes.
Long-Term Healing – 8-Week Program
Best for: Recovering from injury, overcoming joint pain or stiffness, or rebuilding strength safely.
What it does:
This structured plan rapidly strengthens muscle and tendon strength, improves bone density, and boosts circulation over 8 weeks — ideal for overcoming common ailments (like Golfers or Tennis Elbow and Runners Knee or sore ankles) and rebounding from setbacks without overloading joints or tissues.
Use when:
-
You want a long term solution to chronic joint pain or stiffness
-
You're overcoming injury
-
You want to optimise recovery
Sessions progress in intensity based on your body’s readiness. Each session comprises 3 to 5 exercises and takes no more than 20 minutes.
Strengthening – 8-Week Program
Best for: Anyone who wants to build strength efficiently with less strain.
What it does:
Uses Suji’s targeted compression to strengthen muscles faster and increase training efficiency — helping you gain strength while minimizing joint stress.
Use when:
-
You want strength gains without heavy loading on sore or stiff joints
-
You want to improve muscular performance
Works for both upper and lower body strength development. Each session comprises 3 to 5 exercises and takes no more than 20 minutes.
Recovery – Active & Passive Sessions
Best for: Rest days, post-training recovery, and improving circulation.
You can choose between:
Active Recovery
Light movement paired with low compression from Suji. Use when you want to keep the body moving while reducing soreness.
Passive Recovery
Sit and relax while Suji boosts circulation and helps flush the muscles. Use after heavy training sessions, long flights, or competition. Also helps offset soreness after exercise.
3. Troubleshooting: Most Common Questions
Here are some frequently asked questions — and the quick fixes.
“My cuff feels too tight.”
This usually means the cuff was placed too low or the strap is secured too tightly before inflation.
Fix:
-
Reposition it higher on the limb, leave a bit more slack, and recalibrate.
-
Start with a lower compression level. The level of compression applied directly varies the intensity of the session.
“I’m not feeling much activation.”
You should feel noticeable muscle engagement.
Fix:
-
Reposition the cuff higher for better compression distribution.
-
If that doesn't help, re-run calibration from the Profile Tab.
“The app isn’t connecting to my device.”
Often a Bluetooth handshake issue.
Fix:
-
Toggle Bluetooth off/on
-
Ensure the device is charged
-
Fully close and reopen the Suji app
-
Only connect your Suji devices directly through the Suji app
“My session stopped early.”
This is usually a safety timeout or a loose connection.
Fix:
-
You’re using the recovery setting which cycles through compression cycles inflating and deflating. I you want to complete an exercise sessions use the Guided or Unguided setting.
-
Check the device connection.
-
Turn your device off and on to reconnect.
“My Suji won’t turn on”
When Suji powers on, the light should start flashing. If no light appears, the battery may be empty.
Fix:
-
Charge your Suji from the case for at least 90 minutes with the Suji charging cord. Ensure the device is properly housed in the charging case.
-
The device uses a 5V power supply and draws about the same amount of current as a standard phone charger (500mA). Using other cables, large charging blocks meant for a computer or other accessories could affect how well the device performs.
-
Retry (If Suji still doesn’t turn on after charging, contact customer support for assistance.)
“My Suji won’t charge”
Connect a USB-C to USB-C cable from a 5v power source (like a phone charging block or laptop port) to the Suji charging case. Ensure both devices are properly placed inside the case and pressed down so the charging pins located at the bottom of the device can engage with the device.
Fix:
-
Suji can charge even while powered off. To confirm it’s charging, press the power button once — you should see a light.
-
Make sure you are using the provided USB-C charging cable and charging block. The device uses a 5V power supply and draws about the same amount of current as a standard phone charger (500mA). Using other cables, large charging blocks meant for a computer or other accessories could affect how well the device performs.
“My Suji won’t connect to my iphone or ipad”
Fix:
-
Check Bluetooth
-
Make sure Bluetooth is turned on on your device.
-
-
If you previously connected successfully, try unpair/pair Suji
-
Navigate to Settings and then Bluetooth
-
Find your Suji devices
-
Click the “i” and select “Forget this device”
-
Repeat the above 3 steps for the other Suji device
-
Open the Suji app
-
Select the BLE (Bluetooth) icon in the top right
-
Pair devices
-
-
Check Suji’s status
-
Suji must be powered on with a flashing light to be in pairing mode.
-
If the light is solid, Suji is already paired with a device.
-
-
If you have multiple Sujis
-
Try connecting to a different one to see if the issue is with a specific device.
-
-
Check your mobile device’s Bluetooth
- Try pairing another Bluetooth device (e.g., headphones, smartwatch).
-
If those devices also won’t pair:
-
Restart Bluetooth on your phone/tablet.
-
If needed, restart the entire phone/tablet.
-
-
Too many active Bluetooth connections
-
Phones and tablets have limits on how many devices they can connect to at once.
-
If several devices are connected, disconnect some to free space for Suji.
-
“It says my Upper or Lower Body Training Option is Disabled”
This usually means the body part has not been calibrated. You only need to calibrate your dominant arm or dominant leg, not both upper or lower limbs.
Fix:
-
Go to profile
-
Select calibration
-
Calibration dates are shown at the bottom of the Calibration screen
-
If none are showing please recalibrate
“The cuff pressure is not stabilizing”
Fix:
-
Minimize movement
-
Pressure is sensitive. Even small movements can interfere with stabilization. Try to stay as relaxed as possible.
-
-
Check the device attachment
-
For the latest Suji model: remove and reattach the device to ensure it is firmly connected to the cuff.
-
For older Suji (with hose): disconnect and reconnect the hose.
-
-
Inspect the cuff
-
Ensure the cuff is wrapped securely and there are no leaks or damage.
-
-
Reset the device
-
Turn Suji off, wait a few seconds, then turn it back on.
-
-
Check battery level
-
Very low battery can affect performance. Make sure Suji is sufficiently charged.
-
-
Update firmware
-
Go to Profile > Device Manager
-
Make sure both your Suji and your mobile app are running the latest versions.
-
-
Still having issues?
-
Contact customer support or report a bug directly in the app.
-
