Heart rate inaccurate

[CJSC]

I have noticed while I'm at the gym my heart rate and the Stepper I'm using dont seem to have anywhere near the same heart rate. I have tried several steppers and same thing off about 10 beats. Blaze lower. Is there a certain way I should be wearing my Blaze inorder to get a MORE accurate heart rate? Thanks

WHAT IMPACTS THE ACCURACY OF MY HEART RATE READING?

As with all heart-rate tracking technology, whether a chest strap or a wrist-based sensor, accuracy is affected by personal physiology, location of wear, and type of movement.

For all-day wear when you’re not exercising, your tracker should usually rest a finger’s width below your wrist bone and lay flat, just as you would wear a watch. Fitbit’s PurePulse™ heart rate tracking system is designed to be most accurate when the tracker is worn on the top of your wrist.

For improved heart rate accuracy keep these tips in mind:

1. Experiment with wearing the tracker higher on your wrist during exercise. Because blood flow in your arm increases the farther up you go, moving the tracker up a couple inches can improve the heart rate signal. Also, many exercises such as push-ups cause you to bend your wrist frequently, which is more likely to interfere with the heart rate signal if the tracker is lower on your wrist.
   
2. Do not wear your tracker too tight; a tight band restricts blood flow, potentially affecting the heart rate signal. That being said, the tracker should also be slightly tighter (snug but not constricting) during exercise than during all-day wear.
3. With high-intensity interval training, P90X, boxing, or other activities where your wrist is moving vigorously and non-rhythmically, the movement may prevent the sensor from finding an accurate heart rate. Similarly, with exercises such as weight lifting or rowing, your wrist muscles may flex in such a way that the band tightens and loosens during exercise. Try relaxing your wrist and staying still briefly (about 10 seconds), after which you should see an accurate heart rate reading. Note that your tracker will still provide accurate calorie burn readings during these types of exercise by analyzing your heart rate trends over the course of the workout.

Note that if you remove your tracker but it keeps moving, for example if you put it in a pocket or backpack, the tracker may display an erroneous heart rate reading. To prevent this by turning off heart rate tracking when the tracker is not in use, log into your dashboard and go to Settings > Devices to turn your Heart Rate Tracking to "Off."
