Here are a 10 ways your fitness apps can steer you wrong, and what to do instead.

From those two numbers, the little chips in your phone cant help but calculate your pace.

Im running 12-minute miles?!

you might say as you check your watch.

Well, next time Ill have to run faster.

The real workout starts when the warmup ends.

But if youre logging the whole thing, that leisurely warmup brings down your overall pace.

rather than, How can I get better sleep, in general?

Lets say youd ideally like to wake up at 6 a.m.

But any good coach will tell you youll have a tough time making progress if youre afraid of fatigue.

What to do instead: Get a good program (or trainer or coach) and trust the process.

Compare your scores to what you wouldexpectgiven your training.

Low score after a tough week?

High score after a tough week?

Maybe your program isnt challenging you enough.

Low score after an easy week?Nowyou might start questioning whether youve been training too hard.

Trying to decide between a spin class or a hike?

A jog or a strength training session?

Its easy to get into a mindset where steps are the tiebreaker.

Its job isnotto keep your heart rate up for a certain number of minutes.

(Youre thinking of cardio.)

Unfortunately, calorie burn isnt that predictable, andyour watch is just making a wild-ass guess.

What to do instead: Take the scores from your sleep app with a grain of salt.

Pay attention to the total amount and consistency of your sleep instead.

Its just not worth it.

What to do instead: Honestly?

Do a workout without tracking it,on purpose, to free yourself.

Take a weekly rest day.

You probably need it anyway.

If youre able totrack your caloriesand stay mentally healthy, thats great.

But that doesnt mean you have toobsessover your calories.

For example, you may start to feel a sticker shock about any large meal.

What to do instead: Accept that eating food is part of how you fuel yourself.

If youre sure you want to track calories, use an app likeCronometerthat is less visually judgmental about them.

Chasing a good number on pretty much anything

Whats a good HRV reading?

Whats a good resting heart rate?

Whats a good VO2max?

Whats a good running pace?

I wont call these meaningless numbers, because they do have some utility.

But theyre not scores on which you should judge yourself as a person in the universe.

Each number means somethingin context, and doesnt mean much outside of that context.

For example, if you currently run a 10-minute-per-mile pace, it doesnt matter whether thats good.

you’ve got the option to train to run faster, should you choose.

What to do instead: Ask yourself what really matters.

Focus on those ultimate outcomes, not on your daily score.
