Troubleshooting Heart Rate During Workouts

How to get the most accurate reading

Picture this: you’re getting ready to head out for a workout. You turn on your heart rate monitor, and you can’t find your heart rate. No, you’re not dead; your heart rate monitor could just be having a bit of trouble getting a reading. Your Mio heart rate monitor uses the industry’s most accurate technology, but there are a few steps you can take to make sure your heart rate reads loud and clear every time.

First, just try turning off heart rate mode and restarting. If that doesn’t work, try these 5 easy things to get an accurate heart rate reading before you start working out.


1. Keep it clean

If the sensor on your Mio is dirty, it can cause problems. Keep it clean by washing regularly with a wet cloth or by running it under water quickly after each use. Just be sure to dry it off after.


2. Wear it high

Fasten the device about 1-3 inches (3-8 cm) above your wrist bone.


3. Cinch it up

If light gets in, your Mio won’t work well. Tighten the strap so that the optical sensor on the back makes good contact with your skin.


4. Warm up

If you have cold hands or poor circulation, this one’s especially important. Get some blood moving before you get started, and you’ll get a better reading.


5. Hold still

If you’re moving around, it’s difficult for your device to get an initial heart rate reading. Hold still until your heart rate displays, then get moving.


Keep these 5 simple tips in mind next time you’re heading out for a workout or trying to track your heart rate.
