Top 5 from the blog

Wrote a fair amount in 2020, and I hope you have found the blogs informative. Here is my favorite 5:
​

• The ultimate guide to Heart Rate Variability (HRV)
• Biofeedback and athletic performance
• The Pandemic and changes in resting physiology
• What you need to know about night HRV data
• HRV and altitude adaptation in elite triathletes 

Enjoy and all the best for the new year. Hopefully we'll all have a better one

Take care
