While Americans are more proactive about their own health these days and are self-tracking their health metrics, the interest in HRV may also be linked to the ever-increasing focus on wellness and lifestyle medicine. "When I typed 'heart rate variability' into Google, a definition of it came up, and right after the definition was just all the devices that measure HRV," she adds. Vivian Mo, MD, clinical associate professor of medicine in the division of cardiovascular medicine at the University of Southern California, believes it's because technology is giving us the ability to track key health metrics easily in the way of wearable devices and apps (think: Whoop, Fitbit, and other smart health and fitness trackers). On the Internet and social media, it certainly seems like HRV is a health stat many people are excited to self-monitor. If that's the case, you would need to reach out to Fitbit for further information.If you own a smartwatch, you may have encountered a metric called heart rate variability (HRV). If you do not see the "Export as a TCX file" option, your activity likely does not contain any GPS data which is needed to sync to Strava. If you do not have success with the steps above, you can use the TCX export from Fitbit's website to download a copy of your activity and upload it to your Strava account.

Confirm that you recorded a new exercise after connecting your accounts (previous exercises won’t be uploaded).Confirm that you are recording a GPS exercise if using Fitbit (only exercises with GPS on Fitbit will be sent to Strava).Confirm that you are not recording a duplicate exercise in the Strava app and Fitbit app/device simultaneously.
