This guide has been updated with our selections for 2016.

With all the robust technology around to cheerlead you to activity (one step, good work!), you no longer have to rely on the Rocky-era pen and paper to record your workouts. Trackers both obtain and retain all your precious fitness data, and they provide analyses of it so you can see improvement and have some hard facts to back up those impressive endurance claims.

And, perhaps best of all, most trackers today are not only sleek, but fashionable — so you can track calories burned, sleep quantity and quality, heart rate and steps taken without looking conspicuous or unstylish. In short: there’s no more excuses to be sedentary. Peter Saltsman

Apple Watch Series 2


The new Apple Watch Series 2 is the second generation of Apple’s smart watch. It boasts a brighter display, improved battery life, improved water resistance and a built-in GPS sensor. You won’t have to carry your iPhone with you on runs or cycling sessions; simply wear your Apple Watch, which will store your data and sync with your phone once it’s in range.

Compatibility: iOS
Tracks: GPS, heart rate, breathing, sleep, calories
Features: customizable watch faces, smart coaching
Battery Life: 18 hours
Water Resistance: 50 meters

Samsung Gear Fit 2


After wearing the Samsung Gear Fit2 for two weeks, and using it both with an Android device and as a standalone device, it’s clear that average exercisers don’t need to use the companion Samsung Gear and S Health apps. The wristband’s curved AMOLED touchscreen display tells you most everything you need to know: distance traveled, heart rate, pace and calories burned. No smartphone required. — Tucker Bowe

Compatibility: Android
Tracks: GPS, heart rate, accelerometer, gyro, barometer, steps, floors climbed, calories burned
Features: 1.5-inch touch curved AMOLED screen, internal song storage
Battery Life: 3–4 days with typical use
Water Resistance: IP68

Under Armour UA Band


The star of the Under Armour UA Band is the app that accompanies it. The app is well built and gives you easy access to every stat that you could need. It also features a built-in optical heart rate sensor that will give you fairly accurate resting heart rate information, and will integrates with UA’s Health Box scale and system.

Compatibility: iOS, Android
Tracks: steps, sleep monitoring, heart rate
Features: well-built app that links to other apps like My Fitness Pal, Garmin Connect and Apple Health
Battery Life: 5 days
Water Resistance: up to two meters

Xiaomi Mi Band 2


At $45, it’s tough to beat Xiaomi’s Mi Band 2. It’s a fairly standard fitness tracker, along the lines of, say, a Misfit Ray, but it feeds you all of the important stats. The band syncs with Xiaomi’s Mi Fit app — which is simpler than other fitness tracking apps out there, but does a sufficient job.

Compatibility: Android
Tracks: heart rate, steps, sleep
Features: call and text alerts, smart alarms
Battery Life: Up to 20 days
Water Resistance: IP67

Misfit Ray


The Misfit Ray, along with the Jawbone UP4, is one of the best-looking fitness trackers on the market. It’s a small cylinder that can be worn as a band around your wrist, or as pendant on a necklace. What you get from sacrificing a screen and a heart rate sensor is surprisingly accurate sleep tracking and a battery life of up to 6 months, giving you little reason to take it off.

Compatibility: iOS, Android, Windows
Tracks: steps, distance, calories, sleep
Features: call and text alerts, smart alarms
Battery Life: up to 6 months
Water Resistance: 50 meters

Garmin Vívosmart HR+


The Vívosmart HR+ is essentially the same fitness tracker as the Vívosmart HR with an added internal GPS tracker. The Vívosmart HR+ is one of the most accurate running trackers on the market. It keeps track of distance, time, heart rate and calories burned. It’ll also show notifications from your phone, such as incoming texts and calls, so you won’t get separation anxiety. For runners, this Garmin is ideal. But if you’re looking to track other activities as well, the Vívosmart probably isn’t your pick.

Compatibility: iOS, Android, Windows
Tracks: GPS, sleep, all-day steps, calories burned, distance traveled, floors climbed, intensity minutes
Features: push notifications for email, calls, texts, calendar events, ANT+ and Bluetooth Smart
Battery Life: 5 days
Water Resistance: 5 ATM

Withings Activité Steel


If you like the look of an analog watch, but also want the stat tracking capabilities of a fitness watch, look no further than the Withings Activité. Keep in mind, the Activité is fairly rudimentary when it comes to what stats it will track, but it more than makes up for it with its Swiss-made quality and stunningly good looks. The Withings Activité is truly a fitness tracking watch that you can wear every day.

Compatibility: iOS, Android
Tracks: steps, sleep, distance, calories burned
Features: Withings Health Mate app, My Fitness Pal integration
Battery Life: 8 months
Water Resistance: 5 ATM

Jawbone UP4


Jawbone has a way of designing the hell out of their tech for optimal handsomeness, but the UP4 is far more than just a pretty face. Jawbone states that it is an “advanced multi-sensor platform” with a tri-axis accelerometer, bioimpedance sensors and skin and ambient temperature sensors. Those specs make it one of the most advanced trackers available. And it’ll keep its charge for a full week. It’s also water resistant, and with a secure anodized aluminum bracelet it stays put during vigorous activity. The UP4 is essentially the same as the UP3, but with the added benefit of near-frequency paying for those with American Express cards.

Compatibility: Android, iOS
Tracks: steps, calories, continuous heart rate, sleep, perspiration, body mass index and hydration
Features: automatic workout recognition and logging, smart alarm, NFC pay with American Express
Battery Life: up to 7 days
Water Resistance: 10 meters / 30 feet

Polar Fitness A360


While the A360 isn’t small, what it lacks in a slim design it makes up for in features. One of the more beneficial features is its optical heart rate sensor that works well even while swimming, a rarity among fitness trackers. Its touchscreen makes navigating modes and displays easy (though note that the screen doesn’t work when wet or submerged). The A360 also features smart coaching, which can help you to fine-tune your workouts and make better use of your training time. The Polar Flow app that the A360 pairs with is one of the best we’ve seen, with comprehensive graphs and data logs, including a calendar chronicles your improvement over time.

Compatibility: iOS, Android
Tracks: steps, distance traveled, calories, sleep, heart rate
Features: comprehensive mobile app, touch screen, optical heart rate sensor
Battery Life: up to 2 weeks
Water Resistance: 30 meters

Moov Now


The Moov Now automatically tracks your workouts, offers motivation and corrects you with immediate feedback. If your stride is too short, it’ll tell you how to correct it as you continue running. Right hook form needs work? It’ll tell you that, too. The nine-axis motion sensor measures and records specific movements and the real-time audio coach (who sounds a lot like Siri) gives you the feedback. The development team is working on adding even more activities to the Moov’s repertoire in addition to running, walking, cardio boxing and swimming. Plus, you can attach it just about anywhere with the included wrist and ankle straps. Just keep in mind that if you hate being corrected, you might end up giving the Moov that right hook.

Compatibility: iOS, Android
Tracks: sleep, steps
Features: automatic workout recognition, real-time fitness coaching and feedback, ankle and wrists straps
Battery Life: 7 days (time and daily activity), 8 hours (continuous recording)
Water Resistance: 10 meters / 32 feet

Fitbit Charge HR


The Charge HR leads the — well — charge for the most comprehensive fitness tracker of the bunch. Not only is this iteration better designed than the original Charge (the clasp is much more secure), it also offers continuous heart rate tracking, incredibly accurate step tracking and automatic sleep tracking. The crisp OLED screen has caller ID, so you can either stop your workout to take an important call or just continue on without interruption. Integration with Fitbit’s own software is simple, and you can even throw down with your friends via the included Fitbit Challenges. See? It’s not just about tracking, it’s about bragging rights.

Compatibility: iOS, Android
Tracks: workout, steps, stairs, heart rate, distance, calories, active minutes, sleep
Features: time and caller ID display, alarm, strap-free heart rate sensor, running routes, stats, workout summaries
Battery Life: 4–5 days
Water Resistance: 10 meters / 32 feet
