I have been using fitness trackers for over five years now, and I have tried different brands and models. In this article, I will tell you everything you need to know about fitness trackers, their pros and cons, and how to choose the best one for your needs. Whether you are a beginner or an expert, a fitness tracker can help you monitor your progress, motivate you to achieve your goals, and improve your overall well-being. But are they really accurate and reliable? And what are the potential drawbacks of using them? Let’s find out.
Fitness trackers are wearable devices that measure various aspects of your physical activity, such as steps, distance, calories, heart rate, sleep, and more. They can help you track your fitness level, set goals, and get feedback on your performance. Some fitness trackers also have smart features, such as notifications, music control, GPS, and voice assistant. Fitness trackers can be worn as wristbands, watches, clips, rings, or even embedded in clothing. They can sync with your smartphone or computer via Bluetooth or Wi-Fi, and display your data on an app or a website. Fitness trackers can be a great tool to help you stay active and healthy, but they also have some limitations and disadvantages. Here are some of the pros and cons of fitness trackers that you should consider before buying one.
Pros of Fitness Trackers
- They can motivate you to be more active. Fitness trackers can help you set realistic and achievable goals, such as steps per day, calories burned, or minutes of exercise. They can also remind you to move more, challenge you to beat your previous records, and reward you with badges or trophies. Seeing your progress and achievements can boost your confidence and self-esteem, and encourage you to keep going.
- They can help you monitor your health. Fitness trackers can measure your heart rate, blood pressure, blood oxygen, and stress level, which can give you an indication of your cardiovascular health and risk of chronic diseases. They can also track your sleep quality and duration, which can affect your mood, energy, and immunity. Some fitness trackers can even detect irregular heart rhythms, falls, or seizures, and alert you or your emergency contacts.
- They can help you improve your performance. Fitness trackers can provide you with detailed and personalized feedback on your workouts, such as speed, distance, pace, elevation, cadence, and calories. They can also suggest optimal training zones, intervals, and recovery periods, based on your heart rate and fitness level. Some fitness trackers can also coach you with audio or visual cues, or connect you with online communities or trainers, where you can share your results, get tips, and join challenges.
- They can enhance your convenience and entertainment. Fitness trackers can also function as smart devices, allowing you to access your phone’s features without taking it out of your pocket. You can receive notifications, calls, messages, emails, and social media updates, and control your music, camera, or smart home devices.

Fitness trackers are wearable devices that can help you track and improve your physical activity, health, and well-being. They can offer many benefits, such as motivation, feedback, guidance, and convenience, but they also have some drawbacks, such as inaccuracy, unreliability, expense, and stress. Fitness trackers are not perfect, and they are not a substitute for professional advice or personal judgment. You should use them as a tool, not as a rule, and you should always listen to your body and your intuition. Fitness trackers can be a great addition to your fitness journey, but they are not the only or the ultimate factor. The most important thing is to enjoy your workouts, have fun, and be healthy and happy.

- What are the best fitness trackers in 2023?
There is no definitive answer to this question, as different fitness trackers may suit different people, depending on their needs, preferences, and goals. However, some of the most popular and highly-rated fitness trackers in 2023 are:
- Fitbit Charge 5: A sleek and versatile fitness tracker that can measure your heart rate, blood oxygen, skin temperature, stress, and more. It also has a color touchscreen, built-in GPS, voice assistant, and Fitbit Premium subscription.
- Apple Watch Series 7: A smartwatch that can do almost everything, from tracking your activity, health, and sleep, to making calls, sending messages, and playing music. It also has a larger and brighter display, faster charging, and more durability than previous models.
- Garmin Venu 2: A sporty and stylish fitness tracker that can track over 25 activities, including running, cycling, swimming, golf, and yoga. It also has a high-resolution AMOLED display, advanced health and wellness features, and long battery life.
- Samsung Galaxy Watch 4: A smartwatch that runs on the new Wear OS platform, which combines the best of Google and Samsung. It can track your activity, health, and sleep, and also has a rotating bezel, voice assistant, and wireless charging.
- Whoop Strap 4.0: A minimalist and lightweight fitness tracker that focuses on recovery and performance. It can measure your heart rate, blood oxygen, sleep, and strain, and also has a new feature called Health Monitor, which can detect signs of illness or infection.
- How do fitness trackers measure calories burned?
Fitness trackers estimate your calories burned by using a formula that takes into account your personal information, such as your weight, height, age, and gender, and your activity data, such as your steps, distance, heart rate, and duration. However, these formulas are not always accurate and consistent, and they may not account for other factors, such as your body composition, metabolism, or environmental conditions. Therefore, you should not rely on your fitness tracker’s calorie count as an exact measure of your energy expenditure, but rather as a rough guide or a relative indicator of your activity level.
- How do fitness trackers measure sleep quality?
Fitness trackers measure your sleep quality by using a technique called actigraphy, which tracks your movements and restlessness during the night. Based on your movement patterns, fitness trackers can estimate your sleep stages, such as light, deep, and REM sleep, and your sleep duration, efficiency, and consistency. However, actigraphy is not a very reliable or valid method of measuring sleep quality, as it can be affected by various factors, such as your position, posture, or other sources of movement. Moreover, fitness trackers cannot measure other aspects of sleep quality, such as your brain activity, breathing, or snoring, which may require more advanced devices, such as polysomnography or oximetry.
- How do fitness trackers measure stress level?
Fitness trackers measure your stress level by using various sensors and indicators, such as your heart rate variability (HRV), electrodermal activity (EDA), skin temperature, or blood oxygen saturation (SpO2). These metrics can reflect your autonomic nervous system (ANS) activity, which regulates your body’s response to stress. For example, a low HRV, a high EDA, a high skin temperature, or a low SpO2 can indicate a high level of stress, as your body activates the sympathetic branch of the ANS, which prepares you for fight or flight. However, these metrics are not always accurate or consistent, and they may be influenced by other factors, such as your physical activity, emotional state, or environmental conditions. Therefore, you should not rely on your fitness tracker’s stress level as an absolute measure of your mental health, but rather as a relative indicator of your ANS activity.
- How do fitness trackers measure blood pressure?
Fitness trackers measure your blood pressure by using either a cuff-based or a cuff-less method. The cuff-based method is similar to the traditional sphygmomanometer, which inflates a cuff around your wrist or arm, and measures the pressure exerted by your blood on the cuff. The cuff-less method is based on the pulse transit time (PTT), which is the time it takes for a pulse wave to travel from your heart to your wrist. The PTT is inversely proportional to your blood pressure, meaning that a longer PTT indicates a lower blood pressure, and vice versa. However, both methods have their limitations and challenges, such as the accuracy, reliability, calibration, comfort, and convenience of the device. Therefore, you should not rely on your fitness tracker’s blood pressure as a substitute for a medical diagnosis, but rather as a supplementary or occasional measure of your cardiovascular health.
- How do fitness trackers measure blood oxygen?
Fitness trackers measure your blood oxygen by using a technique called pulse oximetry, which uses a light-emitting diode (LED) and a photodetector to measure the amount of oxygenated and deoxygenated hemoglobin in your blood. The LED emits light of different wavelengths, such as red and infrared, which are absorbed differently by the hemoglobin molecules. The photodetector measures the amount of light that passes through your skin, and calculates the ratio of oxygenated to deoxygenated hemoglobin, which is expressed as a percentage called the SpO2. However, pulse oximetry is not a very accurate or reliable method of measuring blood oxygen, as it can be affected by various factors, such as your skin color, nail polish, movement, temperature, or altitude. Moreover, fitness trackers cannot measure other aspects of your respiratory health, such as your blood gas levels, lung function, or ventilation, which may require more advanced devices, such as arterial blood gas analysis or spirometry.
