Please check out my guest post over at the iThlete HRV Blog. Earlier in the season I had done a comparison of a few of the iOS HRV apps and the iThlete one stood well above the others I had been using. They have also made some excellent enhancements to their Pro site which has made my HRV analysis much easier. I have developed a bit of a relationship with them and they asked me to provide some blog posts on how I use HRV in my training. They are also very responsive to their athlete customers and always looking to improve.
I will be providing posts every month on their site relating to how I utilize Heart Rate Variability in my training and life, so check them out.
