Listen up! If you (or your app) are making training decisions based on #HRV data. And that HRV data is shitty (i.e. not coming from a heart rate strap). You're making shitty training decisions.

What is the easiest and most accurate way to monitor #HRV ? In my opinion... A single 1-2 minute test after you wake up (& use the restroom) each morning under the same conditions/position (either lying or seated) With a high quality heart rate strap (polar.com/us-en/sensors/h10-…) And the HRV4Training app (hrv4training.com/) This combination will give you accurate, actionable information on your HRV and how it compares to your normal values over time.
