Heart rate tracking accuracy during workout

[ChakaCon]

I have always loved fitbit but I am about to throw in the towel.  The charge 2 seems so sensitive to the placement on the wrist that while doing any type of interval or weight lifting it does not even detect a heart rate.  Anyone else with this problem?

Hi @ChakaCon, it's nice to see you again participating here in the Community Forums, welcome back!

Thanks for bringing this to my attention, I totally understand how frustrating this matter can be for you. To better assist you with this heart rate tracking concern, can you please let me know when was the first time you experienced this issue and how many times since then? Which activities do you perform? When it comes to heart rate accuracy, please follow the next tips to improve the accuracy when tracking an exercise:

• Wear your Fitbit device on top of your wrist, and make sure the back of the device is in contact with your skin.
• When you’re not exercising, wear your device a finger’s width above your wrist bone.
• During a workout, experiment with wearing the device higher on your wrist (2 finger widths) for an improved fit. Many exercises such as bike riding or weight lifting cause you to bend your wrist frequently, which could interfere with the heart-rate signal if the watch is lower on your wrist. 
• Consider tightening your wristband before a workout and loosening it when you’re done. The wristband should be snug but not constricting (a tight wristband restricts blood flow, potentially affecting the heart-rate signal). 

I'll be here if you need anything else.

It has always been an issue but I am getting serious about tracking all my workouts not just steps.  I will try your suggestion and attempt to wear it higher on my wrist during interval and weight lifting.  Wouldn't that be great if that solved the problem.  Thanks for the advice.  Crossing my fingers.
