Are any of you guys familiar with HRV? Heart Rate Variability. I have a couple friends who base the way they train on results from HRV. The concept seems pretty legit in terms of knowing how well your body is recovered after training and giving an indication on the kind of training you should do that day. I believe its all about the central nervous system and how it recovers from heavy lifts or high intensity work.
