Technology has quickly worked its way into the fitness equipment market. From smart home gym machines to fitness trackers, there are more stats, metrics, and features than lots of us know what to do with.

 

One in five US adults wears a fitness tracker, so for many of us, it’s important to understand what we’re actually looking at in terms of metrics. Without understanding or properly utilizing the many things a fitness tracker can monitor, you’re essentially paying for a glorified wall clock.

In a recent survey, only 30% of fitness tracker users said they found their device “very helpful” in terms of assisting them meeting their goals. I have to wonder if this is because users often don’t really understand the metrics available, which is why I’m here to help you determine what you should be looking at, no matter what your end game is.

Breaking Down The Metrics

“The data coming from your tracker is only good if you understand it,” says Julia LeBlanc, doctor of physical therapy. “But, if you can harness the information and put it to practical use, you can really see changes in everything from your sleep patterns to how your body feels to how your body looks.”

 

Here’s a quick look at some of the most important metrics that nearly all fitness trackers offer:

Steps

Remember watching Frosty the Snowman as a kid? I always loved the “Put One Foot in Front of the Other” song Kris Kringle sang. He was obviously counting his steps via his fitness tracker and wanted everyone to know it. Okay, not true, but he was talking about walking.

 

If there is one metric I believe everyone should track, it’s step counting. Studies have shown that taking 10,000 steps per day can “reduce negative mood, improve BMI, and cardiovascular outcomes.” It’s a great way to improve both your mental and physical health.

 

The step-counting function on a fitness tracker includes all movement from walking to the bathroom to running a challenging marathon. If this is the only thing you want to track, pretty much every single fitness tracker on the market has this feature, so you’re in luck.

 

I’d recommend going for a budget option (for simply step tracking), like the Xiaomi Mi Smart Band 6. At under $50, this user-friendly fitness tracker can monitor things like steps taken, workouts completed and more. Plus, the screen is bright and larger than previous iterations. Win-win.

Calories Burned

If your goal is to gain or lose weight, you might be interested in seeing how many calories you’re burning daily, whether this is through walking the dog or doing an intense HIIT session.

 

To put it simply, calories are units of energy. Your fitness tracker is using information you’ve given it (like your sex, height, and age) combined with heart rate to generate an estimate on how many calories you’ve burned doing an activity.

 

I like the Fitbit Inspire 2 for those who need a weight loss (or gain) focused tracker. This watch gives hourly reminders to move, tracks over 20 different types of workouts, and counts calories burned. Plus, you can track your daily food intake within the compatible Fitbit app.

 

It is worth noting that the number of calories your tracker says you’ve burned in a day is not always taking into account your Basal Metabolic Rate or BMR. Your BMR is essentially the calories that your body burns just to keep you alive. For example, with the Apple Series 6 Watch, you can see your BMR, but you have to open the Fitness app and look at the higher number in smaller print under the ‘Move’ number of calories.

 

It can be interesting to see how many calories you burn in a day, but unless you’re looking to gain or lose weight, it’s not a super important metric to be religiously looking at. It’s also worth keeping in mind everyone’s body needs a different number of calories to work at its best, so try not to compare your numbers with friends or a partner. (I know it can be tempting, looking at all your competitive people out there)

Biometric Patterns: Heart Rate / Oxygen Levels / Breathing Patterns

Looking at metrics like heart rate, oxygen levels, and breathing patterns can be confusing, but they’re a great indicator of your fitness level. Let’s break it all down so you know what you’re looking at:

Heart Rate:

Most fitness trackers continuously track your heart rate throughout the day. Provided you are not on medication that increases your heart rate, you ideally want to see less than 85 bpm, or “beats per minute” when at rest, which is essentially saying how many times your heart beats in one minute when you’re doing something like relaxing on the couch. If you’re running a mile quickly, you’ll see your heart rate spike. When working out, you want to see your heart rate getting high, because it shows you’re exerting yourself and can help long-term with blood pressure control.

 

However, it can be hard to know what a high heart rate looks like for you specifically since everyone is so different. According to the American Heart Association, your target heart rate (and maximum heart rate) will decrease as you get older. For example, if you’re in your 20’s, your maximum heart rate is usually around 200 bpm. Compare this to the average 50-year-old, who has a 170-bpm maximum heart rate.

 

Curious why your heart rate decreases as you get older? It’s simply because older hearts cannot beat as fast or as often as younger hearts can (and you may take in less oxygen as you age).

 

For those interested in finding their maximum heart rate, simply take 220 and subtract your age. The Mayo Clinic says once you know your maximum heart rate, you’ll be able to figure out how much you’re pushing yourself and the heart rate you should shoot for while working out.

 

Want a fitness tracker that can check your vitals and more? The Apple Watch can keep tabs on things like your workouts, daily activity, sleep, calories burned and more. Plus, you can monitor your heart rate throughout the day (not only while working out) by clicking the heart shaped icon on your watch.

 

If you’re looking to hit average exertion during your workout or are just beginning a fitness journey, look to hit between 50% to 70% of your maximum heart rate. For more advanced fitness junkies, hitting 70-85% of your maximum heart rate should give you a vigorous workout.

Oxygen Levels:

Recently, fitness trackers have started being able to track your oxygen levels. This is important because oxygen is what fuels the body, and not getting enough oxygen can be detrimental to your health long-term (plus likely indicates a deeper issue).

 

According to the CDC, a good oxygen saturation range is between 95% to 100%.

 

“If your blood oxygen level is too low, you might experience things like dizziness, high blood pressure, and feeling like you’re having trouble catching your breath,” says pulmonologist Dr. Pena-Hernandez.

 

Fitness trackers like the Garmin Forerunner 245 use a Pulse Ox sensor on your wrist to measure your individual blood oxygen level. The tracker will give you a percentage and the time it last tracked your saturation. Obviously, a fitness tracker is not a substitute for a doctor, so if you feel any of the symptoms of low oxygen, consult a medical professional as soon as possible.

Breathing Patterns:

Ever been so stressed at work that you find yourself holding your breath? Yeah, me, too. When you’re stressed, the hormone cortisol is released into your bloodstream. If you’re chronically in this state, a host of health issues can pop up, including high blood pressure, weight gain, and memory impairment.

 

Fitness trackers like the Fitbit Versa can sense when you’re holding your breath due to stress and guide you through diaphragmatic breathing, which studies have shown can “trigger body relaxation responses.” The Versa also offers meditation videos if you need to have longer calm-inducing minutes.

 

Plus, I like being able to stop every once in a while and take a few deep breaths. It’s a nice break from the hustle and bustle of life and can benefit my health (and yours). Sign me up!

 

These biometric patterns are all things I would recommend tracking, if not for the sole purpose of seeing how your heart rate improves as your fitness level increases. It can be a non-weight related way to see changes as a result of increasing movement and exerting yourself more. These stats can also nudge you into habits that will make for a healthier and happier life (like taking more deep breaths).

Sleep Quality

Getting a good night’s rest is essential for feeling good and having proper amounts of energy the next day. Depending on the fitness tracker, you’ll likely be able to view a variety of sleep stats including restlessness and if you’re getting light or deep sleep.

 

Sleep goes hand-in-hand with being healthy. In fact, long term sleep deprivation can lead to a host of issues including decreased brain function, increase of likeliness of disease, and lowered immune system. This is something that isn’t subjective; you should be concerned with getting enough sleep each night.

 

According to the American Academy of Sleep Medicine and Sleep Research Society, adults should shoot for 7+ hours of sleep each night to feel their best. You’ll also ideally hit 4-6 REM cycles with a solid night of sleep.

 

If you’re willing to sleep in your tracker, the Garmin vivosmart 4 can provide you with insightful metrics to learn more about your nightly slumber. This watch tracks your blood oxygen levels, your REM cycles, and how much you tossed and turned throughout the night. You’re able to view these metrics (and more) though the Garmin Connect app.

 

Studies have shown that “tracking sleep behavior empowers users to engage in healthier sleep habits.” So, even though the sleep tracking you might be getting on your fitness tracker isn’t comparable accuracy wise to a lab’s metrics, it can still encourage you to create healthy habits that will lead to better sleep.

Strain/Readiness

For those of us who struggle to prioritize rest, having a fitness tracker that tells us when to slow down can be very helpful. Recently, fitness trackers have added a handy metric to tell you how ready your body is for physical activity or a strenuous day (scores vary between brands of trackers). These scores are based on the workouts you’ve recently done, sleep, and sometimes even alcohol consumption.

 

As a former collegiate athlete, learning to listen to my body when it wants to rest has been the biggest challenge for me post-grad. I like the Whoop Strap as a tool to assist me in this way because it gives a daily strain score to make sure you’re not over (or under) doing it. This tracker looks at your weekly workouts, resting heart rate, blood oxygen level, and sleep to determine your strain score.

 

I personally like the idea of this new tracking mechanism, but it is subjective. Since every brand is using a different way to calculate the strain or readiness score, it isn’t standardized in any way. Therefore, it should be used more as a suggestion than something everyone must follow.

 

With the Whoop Strap, your strain score can vary between 0-21. Under 10 is considered light, 10-13 is moderate, 14-17 is strenuous, and over 18 is all-out.

 

For example, your tracker might tell you that you’re ready for a hard workout, but your body is telling you otherwise.

I do think it can help promote good habits and make you more mindful of things like prioritizing relaxation, limiting your alcohol, and getting enough sleep at night.

5 dangerous health problems your fitness tracker might pick up

 

You’re counting your steps, tracking your workouts and measuring your sleep with your wearable fitness tracker. But these devices can do more than help you improve your health—the data they track can help you spot dangerous health problems.

Just ask Curtis Carey of Hudson, Wisconsin. His wife gave him a Fitbit fitness tracker for Christmas 2017. After using the tracker for a few months, Carey, now 69, noticed his heartbeat was irregular.

“It would jump up to 130 [beats per minute] then down to 60, then back up and back down,” he says. On the Fitbit app, he could see that his heart rate had been normal for the previous month or two.

He didn’t have any chest pain or discomfort, and a visit to his doctor didn’t uncover any problems.

But by fall 2018, Carey was worried. After strenuous activity, his heart rate would stay above 100 beats per minute for more than two hours.

When a hunting trip left him winded and worn out, he sought care again. A CT scan of his heart showed blockages in three blood vessels, including one that was 95% obstructed.

In March 2019 Carey had bypass surgery to clear the blockages and he’s now well into his recovery.

There are five serious health risks that your fitness tracker could help detect: heart disease, atrial fibrillation, kidney disease, diabetes, and cancer.

Like in Carey’s case, the data from your fitness tracker could show an irregular heartbeat.

Heart rate spikes that aren’t caused by exertion need to be explained, says Felipe Lobelo, an associate professor at the Rollins School of Public Health at Emory University in Atlanta.

Any spikes accompanied by palpitations; pain in the chest, back, belly, jaw, or arm; lightheadedness; sleep issues; or shortness of breath warrant prompt medical attention.

“Those are signs and symptoms typical of cardiovascular disease,” Lobelo says. “Whether they come with or without your Fitbit showing weird data, I think those are important things to check with your doctor.”

Your tracker might also show a sustained increase in your typical resting heart rate. Most adults have a resting heart rate between 60 and 100 beats per minute, and lower numbers generally mean you’re more fit.

Not sleeping enough, nicotine, caffeine and stress can raise your resting heart rate, but a resting heart rate that’s consistently well over your normal rate should prompt a call to your doctor, says Naresh Rao, director of physical therapy at Sports Medicine at Chelsea in New York City and a member of the American Osteopathic Association.

You’ll also want to watch how quickly your heart rate gets back to normal after exertion. That’s one of the most useful numbers you can get out of fitness trackers, Lobelo says. “The number of beats you can recover in the first minute is a pretty good marker of how fit you are,” he says.

Early research is finding that if you exert yourself to 80 to 90% of your theoretical maximum heart rate (220 minus your age) that rate should drop by at least 25 beats per minute in the first minute of rest, Lobelo says. Lower recovery rates may mean you’re at higher risk for cardiovascular disease.

If your heart rate stays elevated for more than five to 10 minutes after exertion, that’s concerning, Rao says. In that case you should see your doctor or go to the emergency room.

The ECG feature on the Apple watch adds heart rhythm to the health features many wearables track. ECGs can help spot signs of atrial fibrillation, a rhythm disorder.

That information is useful, but Rao points out that the watch tracks one aspect of the heart’s rhythm, while medically supervised electrocardiograms track 12 different aspects.

If you sync your wearable with a smart scale you can also watch for unexplained weight gain or loss. Unexplained weight gain could simply mean you’ve taken in more sodium than usual, and your body needs extra water to flush it out.

But it could also be water retention from kidney disease or from congestive heart failure, where your heart is not pumping effectively.

Weight loss when you’re not trying to lose weight could be a sign of various health conditions, including diabetes and cancer.

Rao isn’t sold on the sleep tracking features of wearables. He thinks it’s too early in their development to make meaningful decisions based on their data.

“The jury is still out on that,” he says. “They’re not measuring brain waves.”

And for any health concerns, you won’t get all the information you need from a wearable device. “You typically need more than just a Fitbit. By themselves they are not going to diagnose anything. You need the combination of human touch and technology,” Lobelo says. “But they can provide useful insights for diagnosis and help people achieve an active lifestyle.”
