HRV; What are your experiences?

[peqkno]

Thinking about getting a HRV sensor (HeartMath) for my phone. This isn't mere HRV (Heart Rate Variability) measurement, but training as far as I heard.

If you did any HRV training, which changes and effects could you observe in yourself?

Would you even recommend the HeartMath tools? (or are there other ways or practices which you deem more effective and a better use of time?)

 

In some older threads on neurofeedback tech (not exactly/explicitly HRV) Leo said cheaper tech wouldn't be as good or sensitive enough (as an EEG). @Leo Gura Would you say that same thing about HRV training with tools >200$ ?

HRV is best measured over night to give you a overview about your recovery status.

 

HRV is a quant for parasympathetic dominance, so use it to time your intensity workouts etc. 

Great tool imo
