Best Fitness Trackers to Hack Your Health

Fitness trackers have come a long, long way since we first started counting 10,000 steps a day. You can purchase rings, watches, bands, and other pieces of tech to help you stay in shape, manage your sleep, monitor your heart rate, track those steps, count calories, and monitor other aspects of your health.

According to research done by Sutter Health, a not-for-profit integrated health delivery system headquartered in Sacramento, California, fitness trackers can help you not only get in shape, but also manage chronic conditions like diabetes, or monitor your heart for optimal health.

With so many options on the market, it can feel overwhelming, but deciding what you want your fitness tracker to do is the first step in finding the best one for you. In my case, it’s a simple Garmin Vivofit model that allows me to count steps and stairs, but most fitness buffs will want their tech to do a bit more—so here is a roundup of tools to help you biohack your way into good health.

Best fitness ring and best fitness and sleep tracker: Oura Ring

Oura is one of the OG’s (if not the OG) of fitness rings. It debuted in 2015, and since then, you can find it on the fingers of fitness buffs, celebrities, and everyone else who can afford its higher price point. It comes in four finishes and two styles, and no matter what you select, it still looks like a discreet wedding band.

Oura is now in its 3rd generation and is still tracking things like your body temperature, heart rate, sleep duration, blood oxygen, and more. If you want to hack your health discreetly, the stylish Oura ring beats clunkier fitness trackers. However, this tracker was really designed to help you track your sleep and health versus steps and calories, so if those latter assets are the things that excite you the most, you may want to buy something else.

You must also subscribe to the Oura app, which costs around $70 to access your information and data from the ring. This won two categories for me because not only is it a stylish ring, but it’s also one of the best sleep trackers on the market. (For more about Oura and other similar trackers, see our round-up of the best smart rings.)

Specifications:

• Size (display and/or band): 8 band sizes available; plus, you can order a free sizing kit
• Weight: 4 to 6 grams
• Battery life: Fully charged ring could last up to 7 days
• Display type: N/A, must check info via the app
• GPS: N/A
• Connectivity: Connects to your phone/Bluetooth
• Water resistance: Yes (10 ATM rating)
• Music storage: N/A
• Price on publish: Starts at $299 and goes up, plus an annual subscription

The bottom line:

A sleek, stylish, and comfortable (and waterproof) ring that can track 20 biometric signals—all from your finger.

Best waterproof fitness tracker: Garmin Swim 2

Garmin’s Swim 2 is expensive but worth it if you enjoy aquatic sports and fitness, from swimming pools to open water, offering two modes for each type of swimming. There is a built-in GPS for swimming in open water, like lakes, oceans, and rivers, and SWOLF for pools to gauge your swimming efficiency. This tracker measures distance, stroke count, pace, and more for serious swimming workouts.

It also contains advanced features when paired with the Garmin app, and the watch monitors underwater estimated wrist-based heart rate during swim activities, so you can track your heart rate during sessions. This tracker is waterproof, not water resistant like some trackers (or smartwatches), because it is designed specifically for the water. Shopping tip: If you’re a dedicated swimmer looking to upgrade your workout gear, consider something from our list of the best waterproof headphones.

Specifications:

• Size (display and/or band): 1.04 inch display; fits wrists with a circumference of 129 - 197 mm
• Weight: 1.2 ounces
• Battery life: Up to 7 days (Smartwatch mode), 13 hours (GPS mode), 72 hours (pool mode)
• Display type: Watch face
• GPS: Yes, built-in GPS for open water swimming
• Connectivity: Can be paired with a compatible smartphone
• Water resistance: Yes (5 ATM rating)
• Music storage: N/A
• Price on publish: $249

The bottom line:

This is a waterproof fitness tracker watch designed for serious swimmers who perform aquatic sports in the pool or open water.

How we selected the best fitness trackers

Expert advice and use of products

To create our list of the best fitness trackers, I tried some out myself and spoke with fitness trainers. I asked the professionals what to consider when shopping for and what brands they use.

A variety of budgets

I reviewed a cross-section of trackers at different price points and compared them to create a list with options at every budget.

Diversity of features

The trackers that made the cut all came with a diverse set of features, such as monitoring oxygen, heart rate, calories, counted laps, sleep, location, and even menstrual cycles, to make them stand out in a saturated market of fitness trackers. These are not your average count-your-step fitness bands!

What to consider when choosing a fitness tracker

There are a few things to consider before buying a fitness tracker, including the type of wearable you want and how you will use it. Before you buy one, ask yourself the following questions:

How do I plan to use this fitness tracker?

Some trackers are designed for swimmers, and others are designed for runners. Think about how you plan to use your fitness tracker. Do you want it to track your sleep, calories, steps, or miles?

According to research done by UCLA Health, an LA-based health system connected to the David Geffen School of Medicine at UCLA, fitness trackers, when paired with personalized feedback and encouragement from health coaches and medical professionals, can result in “sustained improvements” in sleep and exercise when users of wearable devices received customized texts and messages. These may be available via apps connected with some wearable devices.

While simply wearing a device may not produce long-term fitness results, using one may bolster efforts to focus on health. UCLA’s research indicated that “integrating wearable devices into more comprehensive, personally tailored behavioral interventions improves compliance and behavior change.”

Of course, finding the right fitness tracker is key, just like finding the right workout shirts. To do that, it’s important to think about your fitness routine, from HIIT workouts to running stairs. Your fitness tracker should be compatible with the sports and exercise you love to do. For example, if you workout in the water, your device should be waterproof. If you lift weights or run for exercise, you may want a heart rate monitor. If sleep concerns you, some trackers will help you develop better sleep habits by tracking your rest.

How much can I afford to spend?

There are budget fitness trackers that collect basic data and there are even free step counter apps that you can access on your phone. The more bells and whistles you want in a fitness tracker, the more expensive it will be.

Do I care about fashion or just form?

My Garmin is slim and black, but I can change the band to purple or blue (depending on my mood). I once owned a rose-gold Fitbit because I loved the color. Some friends love their fashionable and attractive fitness watches. Think about what constitutes fashion for you and how important a color or band size (I prefer something slim) is to you.

How does it charge?

I charge my tracker via my laptop, which can be annoying when I’m traveling. Others come with a self-charging station. Determine how complicated (or uncomplicated) you want your charging situation to be, and always consider how long a charged device will last.

Is it compatible with my phone?

I’m a firm believer that a fitness tracker should be compatible with your phone, especially because most trackers have paired apps or websites. There are so many good fitness tracking devices out there—it shouldn’t be too hard to find the best one to pair with your Android or iPhone.

Frequently asked questions (FAQs)

Which fitness tracker has the best GPS?

There are a few fitness trackers with great GPS systems, including the Garmin Fenix 7 Pro Solar and the Garmin Forerunner 955.

Which fitness tracker does not require a subscription?

There is a movement towards fitness trackers requiring a subscription for optimum support and use, but you can find trackers from Garmin and Fitbit that do not require a subscription.

Do doctors recommend fitness trackers?

Some doctors may recommend fitness trackers. It depends on the doctor.

Is Garmin better than Fitbit?

Garmin and Fitbit both sell high-quality fitness trackers. The one you like the best depends on your personal preference.
