Where should I wear my WHOOP Strap?

The WHOOP Strap should be placed on the wrist, about 1 cm above the bone of your wrist (away from your hand).

The WHOOP Strap should be snug, but not too tight – just tight enough to ensure the sensors make solid contact with your skin.

How do I adjust my band?

You can adjust the band of the WHOOP Strap by pulling the excess band through the bar at the end of the housing. Note that the band should be threaded over and down through the inner slot, then back up through the outer slot. This allows the housing to sit closer to the surface of your skin, and ensures that the sensors can make solid contact.

Watch this video for a demonstration on adjusting and placing your WHOOP Strap:

How do I replace my WHOOP band?

WHOOP sells replacement bands on the WHOOP Store. To replace a WHOOP band, connect the new band’s hook to the clasp of the Strap. Thread the other end of the band through the top of the inner slot of the Strap (i.e. the slot closest to the Strap’s sensor). Feed the band back up through the outer slot so that the end of the band is overlapped on top of itself.

How do I clean my WHOOP band?

The band is easily cleaned in warm soapy water; just rinse the band thoroughly and dry it off.

How do I practice good Strap hygiene?

Clean the WHOOP Strap and the area of your skin underneath the sensor. We recommend the following:

  1. Wash your band as necessary. You can wash your band with soap.
  2. Keep the Strap dry whenever possible. If the Strap gets wet, dry it by squeezing the band with a towel to wring out the water.
  3. If you wear the WHOOP Strap in the shower, take it off and wash the area of your skin under your sensor.
  4. If you experience redness or skin irritation, feel free to wear the Strap on the alternate arm so as to not overexpose one area. This will not affect accuracy of the Strap.
  5. If you have dry skin, consider using moisturizer under the area of skin underneath the sensor.

Does my WHOOP Strap work anywhere else on the body?

The WHOOP Strap is currently designed to work when worn on an athlete’s wrist, about 1 centimeter above the wrist bone.  If you have a bicep band you can also wear the sensor on the outside of the bicep.

How much data is stored on my WHOOP Strap?

The WHOOP Strap can store up to three days of data. If the Strap is not able to sync with the app after three days, the oldest data will be abandoned to make room for more current data.

How quickly will my data transfer?

The WHOOP Strap is able to hold up to three days of data. If the data sync from the Strap to the phone falls behind, once reconnected it will start syncing your data, in order from the oldest to the most recent. Syncing a full day of data takes approximately an hour and a half.

You can check the WHOOP Strap’s approximate battery level by double-tapping the Strap and observing the the LEDs:

  • 3 solid white LEDs indicate a full charge.
  • 2 solid LEDs and one blinking LED indicate a battery between 80 and 99%.
  • 2 solid LEDs indicate a battery between 60 and 79%.
  • 1 solid LED and one blinking LED indicate a battery between 40 and 59%.
  • 2 solid LED indicates a battery between 20 and 39%.
  • 1 blinking white LED indicates a battery between 10 and 19%.
  • 1 solid red LED indicates a battery between 5 and 9%.
  • 1 blinking red LED indicates a battery below 5%.

You can also see your exact battery level from the Overview page and the Strap Status page in the WHOOP app.

How do I connect my Battery Pack to my WHOOP Strap?

The Battery Pack slides onto the Strap via the runners along the side of the Strap sensor. The runners are located just under the clasp along each long edge of the sensor. To connect the Battery Pack:

  1. Ensure the Strap is clasped (closed). The Battery Pack does not fit onto an unclasped Strap.
  2. Find the word ‘WHOOP’ on the Battery Pack and the word ‘WHOOP’ on the Strap.
  3. Slide the Battery Pack over the Strap and along the runners so that ‘WHOOP’ on the Battery Pack perfectly covers ‘WHOOP’ on the Strap.
  4. The Battery Pack will lock into place once the two ‘WHOOP’s perfectly cover each other. The Battery Pack should fully cover the Strap Sensor when the two words are aligned.
  5. To remove the Battery Pack, slide it off in the opposite direction.

Watch this video for a demonstration on sliding the Battery Pack on and charging the Strap.

What do I do if my WHOOP Strap runs out of battery completely?

If the WHOOP Strap completely runs out of battery, simply slide a charged battery pack onto your Strap, and the Strap will turn back on. A fully-charged battery pack will charge the Strap to 100% of its battery life.

Once the Strap turns back on, be sure to connect it to your phone via Bluetooth to ensure that the Strap is collecting data

Is the battery pack waterproof?

Unlike the WHOOP Strap, the battery pack is not waterproof and should not be exposed to water.

How can I order additional Battery Packs?

You can order additional Battery Packs online at the WHOOP Store.

Is there any way to turn my WHOOP Strap off?

The WHOOP Strap will remain powered on as long as it is charged. The Strap will enter a low-power mode to conserve battery life if it is off the wrist and remains motionless. This low-power mode is signified by the green LED on the bottom of the Strap turning off. It’s important to note that the Strap does not collect data when the green LED on the bottom of the sensor is off.

Since I cannot turn my WHOOP Strap off, is it safe to take on a plane considering that it uses Bluetooth?

It is safe to take the WHOOP Strap on a plane and it is safe to put your phone into airplane mode. The Strap can store up to three days worth of data; the Strap will connect with the phone once Bluetooth is re-established, and the data from the flight will be passed through. You can also re-establish your Bluetooth connection after going into airplane mode to allow a continuous stream of data from the Strap to your phone.

Does my WHOOP Strap have built in GPS?

The WHOOP Strap itself is not equipped with GPS; however, you can track your route on workouts such as running and cycling with the WHOOP app using the GPS capabilities of your mobile device (currently only iOS; coming soon for Android). This can be done by selecting Start Activity and turning “Track Route” on for applicable activities. Just be sure when tracking your route that you take your phone with you.

Does my WHOOP Strap have a pedometer?

Rather than measuring steps, as the WHOOP Strap’s built-in accelerometer would allow, the Strap measures Strain, a more comprehensive metric for athletes.

What is the length and width of the WHOOP Strap?

The width of the WHOOP Strap is about 1 inch wide and the length is adjustable to fit any wrist.

What is the weight of the WHOOP Strap?

The WHOOP Strap weighs 0.64 ounces. With the battery pack charging the Strap it weighs 1.16 ounces.

How do I ensure optimal signal quality for monitoring heart rate?

WHOOP utilizes a method called Photoplethysmogram, or PPG, to track your heart rate 24/7. PPG monitors Heart Rate by shining green or orange light through the top layer of your skin. The hemoglobin in your blood reflects the colored light back into the WHOOP Strap’s sensor, and the way in which the light is reflected allows WHOOP to determine your Heart Rate. The faster the heart rate, the quicker the blood flow, the faster the light bounces back.

Here are some best practices to make sure your Heart Rate is being captured as accurately as possible:

  1. Make sure the sensor is kept clean. Some WHOOP athletes do this by cleaning their WHOOP Strap with warm, soapy water while they shower.
  2. Make sure the sensor is snug against the skin even during the most intense workouts. Learn how to adjust your band here.
  3. If it is more comfortable or allows for optimal range of motion in your workout, move the WHOOP Strap up toward the forearm.
