Is your Garmin
overtraining you?

Your Garmin already measures whether you're recovered — resting heart rate, Body Battery, sleep. It just won't tell you what to do about it. Enter this morning's numbers and get a straight answer: train hard, keep it easy, or rest.

From your Garmin this morning.
Your usual baseline.

What the signals mean

This is the whole idea behind Custom Gains: a plan that doesn't adapt is just a calendar. Your coach reads these recovery signals from your Garmin and rewrites today's session so you build fitness instead of digging a hole.

FAQ

How do I know if I'm overtraining?

Look for a cluster: elevated morning resting HR, poor/short sleep, low Body Battery, heavy legs, fading motivation. One rough morning is normal; several signals together mean back off.

Does Garmin tell you when to rest?

It shows the data (Body Battery, training readiness, resting HR, sleep) but doesn't change your plan. You interpret and decide — or let Custom Gains adjust the workout for you.

What is a normal resting heart rate for a runner?

Trained endurance runners are often in the 40s–low 50s, but your own baseline matters most. A reading 5+ beats above normal can mean fatigue, illness, or under-recovery.
