When I first heard about heart rate variability (HRV), I was expecting it to be yet another lame “biohacking” gimmick.

The pitch is by analyzing the rhythm of your heart beat with special software, you can gauge how stressed your body is and adjust accordingly.

For instance, if you wake up and your HRV indicates your body is overstressed, you may want to save the heavy squat or deadlift workout for another day, or if your HRV has been off for several days in a row, it might be time to deload or take a diet break or get a little more sleep.

Again, it sounds like very fake news, but lo and behold, there’s good evidence of its validity. This is why high-level athletes have been using it for years, and now that the technology has become cheaper, it’s becoming more popular among recreational athletes too.

In this episode with HRV expert Dr. Mike Nelson, you’re going to get a crash course in HRV, including how to measure and track your HRV, what lifestyle factors affect it most, how to use it to regulate your training, and more.

Let’s dive in.
