At least, you’re supposed to be.
But lately I’m not so sure.
Somewhere along the way people started outsourcing their judgment to the thing on their wrist.
“My watch says I slept poorly.”
“My readiness score is low.”
“My watch says I shouldn’t train today.”
And I always want to ask the same question:
How do you actually feel?
Because here’s the truth.
Your watch is guessing.
It’s not measuring recovery.
It’s not measuring fatigue.
It’s not measuring how ready you are to train.
It’s interpreting a handful of signals and running them through an algorithm.
Movement while you sleep.
Heart rate patterns.
Estimated sleep stages.
That’s it.
Even the metrics people treat like gospel — heart rate and HRV — are being measured in a pretty questionable way when they come from your wrist.
Your watch isn’t actually listening to your heart.
It’s shining a little green light into your skin and trying to estimate blood flow through your wrist.
From there it guesses your pulse.
Then it tries to calculate HRV from that pulse signal.
All from a device sitting several feet away from the organ it’s supposedly measuring.
It’s impressive technology.
But it’s still a guess.
Real HRV measurement is most accurate when it’s taken from the electrical signal of the heart, like an ECG or a chest strap.
Wrist-based devices are convenient.
They’re also incredibly sensitive to noise.
Movement.
Skin contact.
Temperature.
Circulation changes.
All of those things can throw the readings off.
Sleep tracking is the same story.
Your watch doesn’t actually know when you’re in deep sleep or REM sleep.
It’s estimating based on movement and heart rate patterns.
Sometimes it’s right.
Sometimes it’s wildly wrong.
And yet people wake up feeling great, look at their watch, see a mediocre sleep score, and suddenly decide they feel terrible.
Which is funny, because the exact same thing happens with the scale.
Someone has been training consistently.
They’re stronger.
They look leaner.
Their clothes fit better.
They feel better.
Then the scale jumps up two pounds one morning because they had more sodium, drank less water, or are just holding a little more fluid.
And suddenly they think the entire program has stopped working.
Progress gets thrown out the window because of one number on one day.
The watch just gives people another number to obsess over.
Instead of learning how their body actually feels, they stare at a screen and wait for permission to train.
But your body gives you signals your watch can’t measure.
Energy.
Mood.
Motivation.
Muscle soreness.
Joint stiffness.
Actual performance when you start moving.
The best athletes learn how to read those signals.
Some days you start warming up and realize you feel incredible.
Some days you adjust the plan.
That awareness is part of training intelligently.
Technology can support that.
But it shouldn’t replace it.
Your watch is a tool.
Not the boss.
Use the data if it’s helpful.
Ignore it when it’s not.
And remember something important.
If you eat better and workout more, everything improves, so it really doesn’t matter what the digital readouts say.
Oh yeah, and you are (probably) smarter than your watch.
