6 Best Fitness Trackers 2024: Tested by Fitness and Tech Experts

<h2 class=”body-h2″>Should I Buy a Fitness Tracker?</h2><p>An easy way to decide if you should get a fitness tracker is by identifying a few key metrics you’d like to measure. In a <a href=”https://www.menshealth.com/health/a41193182/heres-which-fitness-tracker-data-is-actually-useful/” target=”_blank” data-vars-ga-outbound-link=”https://www.menshealth.com/health/a41193182/heres-which-fitness-tracker-data-is-actually-useful/” data-vars-ga-ux-element=”Hyperlink” data-vars-ga-call-to-action=”recent article”>recent article</a>, we spoke with Michael J. Joyner, M.D., a human-physiology researcher at the Mayo Clinic, to get his opinion on fitness trackers. “If your goal is to finish a 10K, then the distance you can run without stopping is more relevant than something like your respiration rate,” Dr. Joyner told MH. “You have to ask yourself how collecting more-granular data is going to help you achieve your goals.”</p><p>Before purchasing, take a second to write down your specific needs for a fitness tracker and then list some metrics you’d like to measure. Having an idea of what exactly you will be using your fitness tracker for could save you money and help you <a href=”https://www.menshealth.com/health/a41193182/heres-which-fitness-tracker-data-is-actually-useful/” target=”_blank”>get the most out of your fitness tracker</a>. </p><h2 class=”body-h2″>What Is the Best Fitness Tracker Right Now? </h2><p><em></em>Over the past eight years, <em>Men’s Health </em>has tested well over 50 of the latest and greatest fitness tracker releases, spanning from brands like <a href=”https://www.menshealth.com/technology-gear/a34317600/garmin-forerunner-745-review/” target=”_blank” data-vars-ga-outbound-link=”https://www.menshealth.com/technology-gear/a34317600/garmin-forerunner-745-review/” data-vars-ga-ux-element=”Hyperlink” data-vars-ga-call-to-action=”Garmin”>Garmin</a>, <a href=”https://www.menshealth.com/technology-gear/a22746560/suunto-9-gps-watch-review/” target=”_blank” data-vars-ga-outbound-link=”https://www.menshealth.com/technology-gear/a22746560/suunto-9-gps-watch-review/” data-vars-ga-ux-element=”Hyperlink” data-vars-ga-call-to-action=”Suunto”>Suunto</a>, <a href=”https://www.menshealth.com/fitness/a41286799/apple-watch-ultra-review/” target=”_blank” data-vars-ga-outbound-link=”https://www.menshealth.com/fitness/a41286799/apple-watch-ultra-review/” data-vars-ga-ux-element=”Hyperlink” data-vars-ga-call-to-action=”Apple”>Apple</a>, and more. We’ve seen fitness trackers grow through each generation, which gives us an encyclopedia of knowledge in being able to cross-compare older watch models to their new versions to see if an upgrade is actually worth the price. </p><p><strong></strong><strong>Right now in 2024</strong>, we currently list six fitness trackers that are worth your hard-earned cash, but if you want to know our number one pick before we start that would be the <strong><a href=”https://www.amazon.com/Garmin-Forerunner-Smartwatch-Colorful-Training/dp/B0BS1T9J4Y/ref=sr_1_1″ target=”_blank” rel=”nofollow” data-vars-ga-ux-element=”Hyperlink” data-vars-ga-product-id=”9926b20c-05ce-4e82-82c7-8ae55dac3c74″ data-vars-ga-link-treatment=”sale | (not set)” data-href=”https://www.amazon.com/dp/B09WTV6MMY” data-product-url=”https://www.amazon.com/dp/B09WTV6MMY” data-affiliate=”true” data-affiliate-url=”https://www.amazon.com/dp/B09WTV6MMY” data-affiliate-network=”{&quot;id&quot;:&quot;29242643-49d1-404a-983c-85b499f0f894&quot;,&quot;site_id&quot;:&quot;c7b9f75a-2f85-4251-a92e-dbc6c7213473&quot;,&quot;metadata&quot;:{},&quot;network&quot;:{&quot;id&quot;:&quot;469ce69f-4798-416d-9432-eaa9954b4053&quot;,&quot;name&quot;:&quot;Amazon&quot;,&quot;metadata&quot;:{}}}” data-vars-ga-product-brand=”Garmin” data-vars-ga-product-price=”$299.99″ data-vars-ga-product-retailer-id=”5ae2e533-dc2a-45cb-a03f-f1d3fec960a1″ data-vars-ga-product-sem3-brand=”Garmin” data-vars-ga-product-sem3-category=”Smartwatches” data-vars-ga-axid=”78e1ed90-4586-4317-ae2e-22b866fb39d5″ data-amazon-ascsubtag=”[artid|2139.a.19543741[src|[ch|[lt|sale[pid|9926b20c-05ce-4e82-82c7-8ae55dac3c74[axid|78e1ed90-4586-4317-ae2e-22b866fb39d5[ofsxid|subx_vs_jam[ofsvid|subx”>Garmin Forerunner 265</a></strong>. The tracker is versatile and lightweight, has an easy-to-use interface, and packs a ton of fun extra features—all for a respectable mid-tier price.</p><h2 class=”body-h2″>What to Look for When Buying a Fitness Tracker</h2><p>Fitness trackers can get expensive real fast. To help find the right fitness tracker for you, consider these three key factors first and foremost before looking at shiny features.</p><h3 class=”body-h3″>Accuracy<br></h3><p>The accuracy of a fitness tracker begins and ends with how precisely it tracks your heart rate (most other stats, with the exception of new hydration tracking features, are derived from this baseline data). This mark is as much about pure accuracy as it is about consistency of accuracy, which is key in helping you understand your own fitness trends. We rated Wasimo W1 as the most accurate fitness tracker due to our Fitness Director’s findings on the device.</p><h3 class=”body-h3″>Battery Life</h3><p>With the exception of the Apple Watch Ultra and the Samsung Galaxy Watch 6 (two fitness trackers that are equal parts <a href=”https://www.menshealth.com/style/g33482000/best-smart-watches-for-men/” target=”_blank”>smart watch</a>), the fitness trackers we tested are all designed to run for days (even weeks) on a single charge. We love a fitness tracker that needs minimal charge, and we also love a fitness tracker that can run for a long time when running its GPS mode. Two fitness trackers that surprised us when testing battery life include the Suunto Race with GPS turned on (up to 40 hours on a single charge) and the Coros Pace 3 (over two weeks on a single charge when set to its most basic mode). </p><h3 class=”body-h3″>Durability</h3><p>All fitness trackers are made to take a beating, but some are better designed than others. Look at case construction and screen construction. The most advanced fitness trackers are typically made with stainless steel, titanium, or another type of quality metal. For screens, sapphire glass is a premium spec to look for thanks to its high scratch resistance and strength. Sometimes the most durable fitness tracker is unnecessary, though, especially if you are using it for pavement running. In fact, a plastic construction fitness tracker can be a much better choice for cardio-intensive activities like running and biking, since the material is going to be much lighter than stainless steel or titanium. On the flip side, if you are using your fitness tracker for strength training (or hiking or <a href=”https://www.menshealth.com/trail-running/” target=”_blank”>trail running</a>) it would make sense to look for stronger materials. </p><h2 class=”body-h2″>How We Selected</h2><p>For the past eight years, we consulted with <em>Men’s Health</em>’s fitness and gear editors on the top fitness trackers. Experts, including our Fitness Director Ebenezer Samuel, C.S.C.S., our Senior Editor Brett Williams, NASM, and our Senior Gear and Commerce Editor John Thompson, put countless fitness trackers through the gauntlet and evaluated models on accuracy, design, durability, and price. We update our lineup of fitness trackers seasonally, so you can expect up-to-date information that takes into account the latest fitness tracker releases. </p>”/>

Ditch sit-ups and crunches — this 5-move standing abs workout will help you build a stronger and more sculpted core

The beauty of a standing abs workout is that you do not need a mat, much space, or to get down on the ground for any of the exercises. That makes it easy to fit into a busy day, whether you are working out at home, short on space, or prefer to stay off the floor altogether.

None of that means it is easier or delivers fewer results. Pilates instructor and Balance Body Educator Portia Page built this five-move, all-standing core workout to show that you can still challenge your abs effectively without a mat or traditional floor exercises.

The future of fitness: How AI coaches are changing the way we exercise

The future of fitness: How AI coaches are changing the way we exercise

Fitness and health apps have been promising “smart coaches” and “personalised training plans” for years. But, to date, most programmes have been like online shopping recommendations, with exercises broadly matching your demographic profile and performance level.

However, the rapid advances in real-time image recognition, generative AI and natural language processing are bringing an AI coach worthy of the name within our grasp. And not just for high-tech gyms like Lumin, but also for people working out at home or in the park. Peloton, for example, films how you exercise and provides feedback in real time. Google has also announced AI-powered personalised fitness and health advice for its Fitbit range.

Market analysts think the AI fitness market could be worth close to $35b USD by 2030. But how close are we to that future? Which company is training up the supertrainer? And how will that change the way we exercise, sweat and track our progress? And what do we need to know about this new world?

Most fitness apps give generic exercise suggestions

Confidence Udegbue has the perfect CV for designing an AI coach. The Vice President of Product at fitness app Freeletics studied electrical and computer engineering and teaches fitness classes in his free time. His broad shoulders, muscular biceps and infectious spirit are a dead giveaway: this guy knows what he’s talking about.

“In the gym, I can see immediately when someone I’m teaching is making a mistake,” says Udegbue. “But that expertise is hard to scale.” Freeletics is trying to solve that problem with AI. The app has been using a predictive algorithm since 2019 to suggest workouts based on demographic data and self-assessed fitness levels. This means that a 39-year-old man who has been training for two years and is at level 63 in the app won’t receive the same instructions as a 25-year-old beginner.

Freeletics uses AI-based motion analysis powered by models like those from Google’s MediaPipe framework, which includes BlazePose – the successor to the earlier PoseNet model. The models provide a skeletal muscle database that can replicate all types of exercises, for which Freeletics sports scientists then define the movements. That way, the system can assess whether that squat you just did went low enough.

Can an AI coach give useful real-time workout feedback?

In 2024, Freeletics introduced the Coach+ feature – an AI-powered chatbot with Freeletics expertise and access to anonymised data from over 59m user journeys. Users can ask the virtual coach questions like, “How can I build muscle mass?” or “I feel weak – how can I motivate myself?”

Freeletics is currently testing a version that will allow the app to see you work out. As of April, users have been able to record themselves exercising on their smartphones. “AI counts the reps and gives direct feedback,” Udegbue says. That is particularly helpful because even experienced athletes do not always perform pistol squats or burpees correctly.

Democratising the personal coach experience

A personal coach was long the preserve of Hollywood actors, top models and CEOs – a highly competent service provider, always available whenever a slot opened up in their client’s busy schedule. They know their clients’ allergies, preferences and weak spots. They always know how to set the pace. Sometimes they’re pushy, sometimes they go easy. They are a mix of therapist, personal assistant and best friend – open 24/7, all major credit cards accepted.

In the soccer world, the manager is often called “boss” – a figure of respect who takes care of the players both on and off the field. A good coach can tell when something is off in a movement – when the person’s mind is elsewhere, or they’re lacking energy. Anyone who has had that person in their life knows that a good coach is worth their weight in gold, which is why there are coaches for everything – careers, relationships, nutrition – and why the idea of a personalised fitness coach is so appealing.

AI has no body or talent. It doesn’t know what it feels like for sweat to run down the skin or for muscles to cramp or for adrenaline to rush through the veins. But it does recognise patterns and make predictions that we humans can use increasingly often and, in the best-case scenario, find out more about ourselves in the process.

Mirrors show you how you see yourself. But the Magic AI Mirror promises that you will like what you see if you follow the exercises and tips on the reflective screen. Behind the glass surface is an AI coach who steers your workouts in real time.

Growl goes even deeper into movement detection. The start-up has developed an exercise boxing bag that captures every movement with 3D cameras and Lidar (light detection and ranging) technology. AI corrects your posture or encourages you when your energy decreases.

Whoop’s fitness trackers combine biometric data with generative AI. If you’re wondering when you got your best sleep, you’ll get a precise answer: “On July 14, because the allergy season was over and you didn’t drink alcohol.” You can chat with your body.

Freeletics is also banking on predictive AI. “Soon the system will recognise that user X has had an increased resting heart rate for days, so I won’t suggest high-intensity exercises,” says Udegbue.

The vision all companies are working on is a multimodal coach: AI that unlocks information – biometrics, genetics, video, training history – and conveys it intuitively to the user. But a perfect coach is more than just an algorithm. Researchers are working on reinforcement learning systems that set individual step goals that are challenging but achievable, and adapt whenever progress has been made.

“We will not be able to deliver on the promise of absolute personalisation for the mass market,” Eskofier says. But before you lose hope, you should know what he means by personalisation.

His laboratory supports, among other people, Sebastian Steudtner, the big wave surfer and world record holder. To do this, they measured his body in an MRI scanner, carried out psychological assessments, calculated strength curves and even fitted his surfboard and wetsuit with sensors.

Eskofier’s team created Steudtner’s digital twin. By the time the project concluded in May 2025, their AI system could already discuss with a real coach what angle Steudtner should surf a 100-foot wave at, and whether he’d be strong enough to do it.

“We can’t offer that service to millions of people,” Eskofier says. “But these systems can still create real added value.” He believes AI coaches are a good base: “AI can take over data processing and routine personalisation, while real coaches can focus on mentoring.”

AI coaches are getting smarter all the time, too, which is why it’s important to know what they can and can’t do. Limited data sets can lead to bias if too few women or people of below-average height are represented in the data.

“No matter how good the technology gets, one thing will never change,” says Udegbue. “A coach can only make you better if you want to be better yourself, too.” It’s all in your hands.
