Does anyone here monitor their heart rate variability (HRV) to determine if they are overtraining? Is it useful?
I'm training heavily for the Hunstman Senior Games in October, and I want to make sure I don't overdo it. If HRV is a good measure of fatigue, I can use it to guide my training load.
The Apple Watch records HRV, so it's pretty easy to measure. I notice that after longer and harder workouts, my HRV will drop the next day, but it comes back up in a day or two.
