Did you know that elite athletes can lose up to 11% of their performance capacity after just one night of poor sleep? That’s unfortunate but true—while you’re working hard through those early morning workouts and giving your best to eat the best you can for your fitness goals, a lack of sleep could be silently sabotaging your athletic goals, no matter if you want more muscle growth, strength, or cardio!
As an athlete, you already know that recovery is just as important as the workout itself. But you can’t know how much improvement you need and where do you need to start if you don’t measure. That’s where sleep trackers come in. These devices have evolved far beyond simple step counters—they’re now essential tools that provide deep insights into your sleep cycles, recovery status, and readiness to perform.
This topic is very important to me, and that is why I did my best to find the best sleep trackers specifically for athletes and their performance. Whether you are looking to lose fat, gain muscle, or be a professional athlete, knowing how to improve your sleep might be able to improve your performance drastically. In this guide, I’ll walk you through the best sleep trackers available in 2025, breaking down their features, accuracy, and real-world performance benefits so you can choose the one you want and need the most.

Why Sleep Tracking Matters for Athletic Performance
Whatever your goal might be in fitness, whatever you want to do as a hobby or become a pro athlete, one thing everybody needs is growth hormone, and during sleep, your body releases 75% more growth hormone than when you are awake. This is when muscle repair and tissue regeneration happen. Also, Sleep triggers protein synthesis, which is essential for building and repairing muscle fibers damaged during training, and if you don’t sleep properly or enough, the likelihood of you getting injured and hurt during the next training session skyrockets.
If you sleep poorly for just one week after a good sleeping routine, testosterone levels will drop by about 15% for both men and women.
Sleep deprivation affects reaction time, endurance, and strength gains:
If you don’t get the optimal amount of sleep, your reaction time will be much slower, as multiple studies show. The same thing with long-distance endurance activities, where some studies show If you don’t get a good amount of sleep, you will get tired 21% faster than if you were to get a healthy amount of deep and REM sleep. Some athletes even showed signs of lower pain tolerance, and they found their workouts much more difficult and painful when they were not optimizing their sleeping schedule. Other similar side effects are slower decision-making and worse concentration.

Why are sleep cycles extremely important for sleep quality?
Another great reason to get one of these devices, especially if you are an athlete, is that they calculate how long you slept in which cycle and how to optimize your sleep if you didn’t get enough of it.
Their is three main sleep cycles, and they are REM sleep, deep sleep, and light sleep, and you need all three for optimal performance. If you are deficient in one or more sleep cycles could create a lot of problems with your recovery, performance, and health in general.
Deep sleep is when most of the physical recovery happens, which means that when you are in deep sleep, your muscles repair and grow stronger, your bones strengthen, and your immune system fights against illnesses. That is the reason why when you are feeling sick, you can sleep a lot because that is your body telling you that you need sleep and rest.
REM sleep is crucial for cognitive recovery,y which means that motor skills, learning new skills, concentration, and overall mood are all dependent on how well you slept last night.
Light sleep acts as a transition stage between REM and Deep sleep, but it still contributes to around 50% of total sleeping time.
Hopefully, now you understand that sleep is so important for your fitness and athletic goals, and no matter how hard and well you are training, if you don’t have your sleep under control, you will not get far.
There has been high-level research done on this topic. One of the best studies is from cureus.com, and you can read it here.
How accurate sleep data can prevent overtraining syndrome and reduce injury risk?
If you start measuring your data accurately, which you will be able to do with any of these tools that I selected as the best on the market, your risk of overtraining and injury will plummet to the floor because you will have all the information you need for the best recovery.
Some interesting and also scary things that will occur if you don’t have a proper sleep routine are:
- Slower muscle recovery and increased soreness
- Decreased strength, power, and endurance
- Slower reaction time and coordination
- Higher risk of injuries (strains, sprains, overuse injuries)
- Reduced focus, concentration, and decision-making
- Lower motivation and mental fatigue
- Hormonal imbalance (lower testosterone, higher cortisol)
- Weakened immune system → more frequent illness
- Poor energy levels during training and competition
- Reduced overall athletic performance
Top Sleep Trackers for Athletes in 2025 (Detailed Reviews)
Oura Ring Gen 4
So, if you don’t want to have a tracker that is extremely useful in one specific area but lacks a lot in other areas, this ring is a perfect fit for you because it is very well-rounded and my best overall pick. Oftentimes do people focus only on one small thing and they obsess over it, and later they realize that it was not worth it buying the whole product over one specific thing. If you don’t want to make that mistake, I recommend Aura because they have the best overall quality of a product.
This specific design is very lightweight, and it weighs less than 6 grams, and there is multiple color options from Black, Brushed Silver, Stealth and Rose Gold. Oura has incredibly accurate HRV tracking, which is measured during optimal sleep periods for consistency. Readiness score will provide you an incredible overview that shows how hard you should train that day to train to your fullest intensity potential, but also to prevent unnecessary risk of injury and overtraining. Another huge thing that shows how good is Oura is its battery life, which usually lasts for around a week before shutting down.
Product Pros
Product Cons
Whoop 4.0
This model is specifically ideal for serious athletes who want comprehensive strain and recovery analysis. This screenless band is famous for its comfortable appeal and being waterproof for both showering and even swimming.
Whoop Is very detailly calculates training strain and what is the optimal recovery time after a workout based on how long and well you should sleep. Also, there is a lot of personalization in the app where you get a plan personalized to you and your goals, for example, a person who trains 3 times a week should not have the same recovery process as the person who trains 6 times a week hard.
The app will also measure sleep debt and tell you how much sleep you are behind for optimal health and physical performance.
The unique and interesting thing about Whoop is that the actual device doesn’t cost money, but they make money by charging you a fee, which is 239 dollars a year or a monthly plan, which is 30 dollars per month.
CONS:
As I already said, this Whoop doesn’t have a display, which means that you have to use the phone app to see any data. This is very important, and I know it will be a big problem to some people who are already used to devices and smart watches that you can see the data from. I believe that everybody can find solid use of Whoop 4.0, but it will be absolutely incredible for athletes who want high-level data and stats.
Garmin Forerunner 965
The first fitness-focused smart watch that I ever got was a Garmin, even though it was not this model, I than already knew that they had absolutely incredible products overall. I mean, with its whole system, Garmin is always one of my top recommendations in this topic. Besides the regular smart watch things, Garmin is highly detailed with what you can do when we talk about fitness and recovery. One of those is, of course, today’s topic, which is sleep.
With Garmin Forerunner 965 you will have a lot of high-quality features, but without a doubt in my opinion and experience,e the most important and well-made feature is calculating sleeping stages. Garmin in general, is very accurate when we talk about sleeping stages and how to optimize them.
Some other features on this Garmin watch are how stressed you are during sleep and how often do you wake up through the night, with, of course, HRV status, pulse OX, and respiration.
OTHER FUNCTIONS
Besides its well-made recovery options and programs, Garmin’s AMOLED display is one of the highest quality and most durable on the market. This specific watch can go for more than 20 days in smartwatch mode, and it has a 31-hour battery in GPS mode. This is a very good battery compared to the average industry standard, and it will be more than enough for most people, and it will be even enouph to hikers.
CONS:
The number one con in this case is its size, beacause it is a smart watch it is of course larger, bulkier and heavyer than any rings or bands which can be a problem to some people because it will not be as comfortable during sleep and you will always fell that the watch is there unlike the ring where it blends in like it is a part of you until you cant feel it anymore. But from the other side, you can see every single statistic on you watch, which makes you not need your phone, unlike rings and bands, which don’t have a screen.
The other con is its brightness; Garmin watches are very light even on the lowest brightness, which can disrupt you in the middle of the night. This, to me, is a big deal because I am a big believer in no lights before sleep for better sleep, and believe me it can absolutely destroy your sleep for the rest of the night if you wake up in the middle of the night and accidentally see some bright blue light. It doesn’t help that the watch’s screen gets turned on with movement so even if you turn your wrist slightly, it can turn the watch on.
In conclusion, this watch is best for runners and multisport athletes. Even though this watch is usefull not matter your sport, I feel like Garmin’s Forerunner 965 is specifically made for runners with its incredibly deep and detailed programs and extensions for runners. I would also recommend this device if you are multi sport athlete because Garmin has a ton of options when we talk about wide range of different sports.
Apple Watch Series 10
Apple’s watch series is a good fit for all users but I would especially recommend it to people who already often use iOS phones and other devices, because there will be better integration and a bigger list of fitness apps that you can get for your smart watch.
Apple Watch tracks everything you need from sleep stages, respiratory rate, wrist temperature, blood oxygen etc. There are also very important health tools that go beyond just physical recovery, but also very serious sleep disorders like sleep apnea detection,r which is FDA checked and cleared. There are also some other reliable health sensors. They specifically partner with some athlete-focused apps like HRV4Training and Training Today, which definitely improve user experience and expertise on athletic recovery.
OTHER FUNCTIONS
Apple Watch series 10 has very fast charging which can get your watch to around 80% in just 45 minutes, but even thou it can charge fast I recomend you always make sure that the watch is full by the time you go to sleep to be 100% sure you are going to have reliable information throw the whole night, which is probably the most important part of your recovery as I said earlier why.
CONS:
Because the watch is always on display, the battery will be always be drained faster than if the display was turned off, and this might also be a problem when you are in bed because the blue light might disturb your sleep.
As I said earlier, this watch performs the absolute best if you are already using an iPhone, which could be a problem to some Android users because they will know that they can’t access all the features that they paid for.
FitBit Sense 3
This definitely is one of the best or some would even say the best, budget-friendly options on the market currently. This is a great alternative to 600 or 700$ watches that are not 3 or 4 times better, even though they have that high price.
Even though this watch is a lot cheaper than many on the market, and many that I talked to today about it have all the features others have like calculating sleep stages and the time you have been in each and every one. EDA stress sensor both during sleep and waking hours, which will calculate and tell you what you need to do to calm down and both mentally and physically relax, and also Sp02 as well with skin temperature variation.
In my opinion, many people get above their needs and understanding, which can lead to less productive use of the device that you bought because they don’t know how to use it properly. This Changes with Fitbit Sense 3 because their UI design is so well-made and easy to understand. This shines with a straightforward sleep score that’s easy to interpret for beginners.
With a battery life of almost a week and fast charging,I don’t think that battery will be a concern for anybody. Also, Fitbit watches are known to be very comfortable to wear, mainly because they are lightweight and of quality material that will not irritate your skin.
With its amazing recovery program comes solid workout tracking features with over 40 exercise modes.
CONS:
Fitbit has a regular subscription that comes for free with the watch, but there is also a premium subscription that costs $9.99 per month that unlocks very detailed analysis and more personalization options.
To some people might not be fair for a budget alternative to have a subscription model, but I am telling you again that a premium subscription is not needed at all and that you have more than enough in my opinion to work with in the free option. However, if you feel like it can improve your recovery even more, you should consider it.
Some of the recovery analysis, even though precise, is less detailed than Whoop or Oura.
CONCLUSION:
If you are an athlete who is new to sleep tracking and athletic performance watches and trackers, I am confident that this is a perfect match for you because it is easy to understand and use, and you are not making a huge investment that might be a bad one in the future.
COROS Apex 3
With its absolutely insane 17-75 day battery life, there is no doubt that COROS Apex 3 has the best battery in the game, and it is especially useful for ultra runners that depend on these watches for optimal performance. The battery life depends on usage mode, but even with the highest spending usage mode it lasts over 2 weeks, which is levels above its competition.
It has all the essential tools as other smart watches in this category do, such as sleep stages, HRV, Sp02, and a 24/7 non-stop heart rate tracker, and many other tools similar to them. EvoLab, which is a training hub from COROS, provides science/backed training insights that will tell you how much recovery and sleep you need. Its rugged and protective design is very durable for all sorts of conditions.
Excellent GPS accuracy will get the job done for all kinds of trail running and mountain activities, which involve challenging and tough terrain.
CONS:
In my opinion, the bigest weaknes of this watch is the sleeping part because the watch is a little bit big and uncomfortable to have on you while sleeping, and also its sleeping analysis is less detailed compared to some other brands and watches I talked about today.
CONCLUSION:
This Watch is amazing overall, but I would still recommend it mostly to people who want to have specific things that COROS shines at, like battery life and durability. If you don’t find those things very important, I would recomend to choose the better overall watches from this list.
Withings Sleep Analyzer
Now this might be a little be diferent from the other products that I talked about in this article, but believe me, it does the same or even a better job than other devices for a lesser price. The main benefit of the Withings Sleep Analyzer compared to smart watches is that this option was specifically focused on improving your sleep, while smart watch makers have to focus on other things like music or calls or even games on some smart watches.
If you are mostly interested in sleep improvement, this is a no-brainer for you with its incredibly accurate sleep tracking and other things like a snoring checker, heart rate, and breathing disturbances. There is also a sleep apnea detection with an absolutely impressive medical-grade accuracy that might save you from far more expensive alternatives.
OTHER OPTIONS:
Unlike any of the other products on the market, where you have to have them on your body in order for them to work, you just have to put this thin pad under your mattress in order for it to work you. And even though it tracks everything with amazing accuracy, it is completely unnoticeable during sleep. This is even more impressive considering that you don’t have to atach your self to it in any way so no buttons or wearing required. It also integrates very well with Apple Health, Google Fit, and other platforms similar to them.
CONS:
Unlike wearables, a sleep analyzer can’t track HRV or body temperatures so if that is something important to you consider buying other options that I listed above. It also requires a permanent position under the mattress so it can not be used for travel.
FAQ
Do sleep trackers really improve athletic performance?
Sleep trackers technically don’t improve performance by themselves, but they will give you the information which will help you make smarter decisions like adjusting training intensity, preventing overtrainin, and adding time to your sleep schedule.
Can I use my regular smartwatch for sleep tracking?
Yes, most modern smartwatches include some sleep tracking features by default. However, these features come nowhere close to specialized devices, especially the ones that were listed in this article.
Are rings better than watches for sleep tracking?
Yes, I would say so, and most people would agree with me, mostly because of how comfortable they are, but unfortunately, they don’t track workouts comperhensivly and some don’t even track workouts at all, which is why I personally use a Garmin watch.
Is it worth paying for a sleep tracker subscription?
That depends on your personal financial situation and goals. I often tell people that they don’t need most subscriptions because they get most things they need in the free versions, but if you feel that advanced versions will help you than you should definitely try them.
Do I need to wear a sleep tracker every single night?
You definetly should at least try to wear them every single night, but if you slip up ones by having it on the charger or just simply forgeting it is not a big deal that you have to stress about.
How much sleep do athletes actually need?
I am a big sleep fanatic, and I believe if you are an athlete, you can’t function and perform how you should without at least 8 hours of sleep per night, and if you are in a heavy training session, you should sleep for around 9-10 hours per night with occasional naps.
Conclusion
Your goals and dreams don’t just depend on how hard you train—it’s fundamentally shaped by how well you recover. The best sleep trackers for athletes in 2025 offer all the insights into sleep tracking that you need. My overall best pick is the Oura Ring with its extremely advanced and accurate HRV tracking. Also, there is a comprehensive Whoop 4.0 system designed specifically for serious athletes. I found a great product for you, no matter the budget, style, or needs.
I encourage you to start with the fundamentals: establish a consistent sleep schedule, optimize your sleep environment, and give your chosen device at least 2-3 weeks to establish your baseline. The patterns you discover might surprise you—and they’ll probably transform how you look at recovery going forward.
