What it is‍

HRV stands for Heart Rate Variability

Your heart doesn’t beat like a metronome - perfectly evenly. Instead, there are small differences in time between each heartbeat.

Those tiny changes can be measured, and they naturally go up and down based on what’s going on in your body.

That’s HRV - how much your heart rate varies from beat to beat.

What it means

At its core, HRV reflects your nervous system - how well you’re balancing stress (“fight or flight”) and recovery (“rest and digest”).

When your body is well-recovered and adaptable, HRV tends to be higher.
When your body is stressed (training, poor sleep, alcohol, illness, life stress), HRV tends to be lower.

So… what do I do with it?

If you track your HRV, the goal isn’t to obsess over the number - It’s to use it as a guide.

Think of it as a daily check-in:

Higher than your normal? You’re likely recovered - good day to push a bit

Lower than your normal? Your body might be under stress - consider dialing it back

That doesn’t mean you skip every workout when it’s low. It just helps you adjust—maybe you go lighter, move slower, or focus on recovery instead.

Over time, HRV can also help you spot patterns. Poor sleep, high stress, alcohol, and hard training blocks will usually show up in your numbers.

Bottom line:
HRV helps you train with your body, not against it.

REMEMBER:

HRV is highly individual—it’s not about comparing your number to someone else.
It’s about your trends over time.
