Buying Guide

1. Why are Regular Fitness Trackers Not Suitable for Weight Lifting or Crossfit?

There are two main reasons to mention here. First, they are not capable of accurate heart rate monitoring. Second, they cannot track individual exercises like weight lifting or crossfit.

Inability to Accurately Monitor Heart Rate

Exercises such as weight lifting or crossfit require non-stationary movements such as wrist flexion, rapid and intermittent lifting or lowering. It is completely different from normal walking or riding. Conventional fitness trackers are often not capable of accurately recording these heart rate changes, leading to you misjudging your training progress.

DO NOT Track Individual Workouts

Most regular fitness trackers will only track metrics like total workout time, heart rate, distance, or steps. However, those who practice weightlifting or crossfit need more than that because these workouts are specific.

2. What to Look for When Buying Fitness Watches for Weightlifting and CrossFit?

Database of Exercises and Movements

This is often the weakness of conventional fitness trackers as they only present rudimentary data without analyzing and reporting your performance when performing those exercises or movements.

Ignoring those disadvantages, the best crossfit fitness tracker allows you to track your progress in past exercises. What you really need if you are pursuing weightlifting or CrossFit is access to a large data source about exercises as well as the ability to track body metrics instead of an “almighty” watch but do not specialize in any feature.

Create Your Own Workout

It’s great if you can create your own schedule and fit each stage before going to the gymnasium. It helps to control your weight lifting time as well as support you in reaching your maximum goal in the gym. If so, Garmin Fenix 6 and Polar Ignite are said to be the optimal choices at this point.

Counting Reps (Repetition)

Very few fitness trackers automatically count Reps in exercise. The Reps counting feature is extremely important when you’re lifting weights or doing Crossfit. You can find this feature in Apple 6 or Garmin Fenix 6.

Accurate Real-time Heart Rate Monitoring

As mentioned in the previous section, regular fitness trackers can not do a good job of measuring heart rate in specific subjects like CrossFit and weightlifting.

3. How to Use The Fitness Tracker Effectively

When you perform activities such as running, CrossFit, weight training, strength training, or other sports, the fitness tracker will evaluate accurately. To do so, you need to know how to wear it and set up it in its best working model.

Not only in moving exercises but in-situ men and women cardio, fitness watches also have good evaluation parameters.

How to Wear

Health watch manufacturers recommend everyone wear it on the wrist – the place where there are a lot of blood vessels going under the skin and closest. It allows controlling heart rate, blood pressure almost like measuring at the chest.

When wearing, the strap should be tightened moderately. Thus, the lower sensor of the watch will measure the pulse rate naturally without spasms, and the measuring distance is also more accurate.

How to Install Apps and Use

Using a health monitoring wristwatch, you will often connect to a smartphone to synchronize data and monitor more accurately. It will clearly show all your biometric metrics and activity metrics according to the chart. Each brand will have apps installed on the accompanying smartphone for synchronization.

In addition to installing the app sync with the health monitoring device, you also need to set up the metrics you want to track. You should turn off the features you deem unnecessary and turn on those you deem necessary.

See The Parameters Displayed on The Tracker

If you only know how to use the health meter without paying attention to viewing the parameters of each feature, it is probably not enough. You need to also know how to fully read those parameters and understand them. Commonly, the manual is also introduced for you to understand, but you need to learn some more health information.

Sportspeople probably cannot ignore this problem. It allows you to find the best ways to run, lift weights in every workout. Those parameters will be clearly shown when you need them.

You also need to know how to switch the view on your device’s display. Thanks to that, you can read the parameters you want to see. When knowing how to use the health meter most effectively, you can adjust each exercise on your own anytime, anywhere.

4. How to Choose a Suitable Fitness Tracker

The advice is to choose the appropriate device platform. These include operating system, compatibility, price, and battery life. All smartwatches today have the ability to pair with smartphones, the problem is you need to find one that supports your phone’s operating system.


Apple’s smartwatches (Apple Watch) only support iPhone, while Google’s Wear OS devices mostly support both iOS and Android. In addition, smartwatches using the custom operating systems of Huawei, Samsung, Garmin, Polar and other manufacturers are also compatible with both Android and iOS (you must install an additional private support application)

Besides, the smartwatch operating system will also decide the type and number of apps for your smartwatch. However, you should remember that many of these applications are not really useful.


Good smartwatches usually have prices ranging from $200 to 350, more expensive compared to cheap smartwatches that often cost between $100 to 200. More expensive devices often add fitness, music features and integrate advanced connectivity such as GPS, music storage, or NFC connectivity.

In addition, specialized sports smartwatches can cost over $500, which is suitable for serious exercise lovers.

Battery life

Battery life remains one of the major weaknesses of smartwatches. Recently, technology has made strides to increase the usage time to 2 days for new Apple Watch and Wear OS devices.

The Apple Watch is often “hated” because of its “modest” battery life. While Garmin has a much more expensive price, it has longer battery life. The Fitbit and Huawei watches have a battery that lasts about 2-3 days.

And of course, its features are also in the mid-range. That’s it, the choice is up to you. Please consider the amount of battery when choosing a smartwatch. The battery is also something that you need to keep in mind when buying a smartwatch because not everyone is willing to charge the battery every day.


An undeniable trend is that watch brands are increasingly “cramming” more features into their products. Familiar features such as GPS, heart rate measurement, sleep monitoring, etc previously only appeared in the health monitoring watch, are now also integrated into smartwatches. Some other common features that are often found are the ability to listen to calls, listen to music, and notify messages.

You should clearly define your needs at this point. Is your need “work” or “health” one? If you often participate in outdoor activities, a Garmin brand watch is very suitable. On the contrary, it is not suitable if you are a genuine “officer”.

You should choose smartwatches that have the right features for you, rather than “whatever” watches. And don’t forget that integrating too many features also significantly reduces the battery life of the watch.

Possibility of personalization

Today, smartwatch brands often focus on the ability to personalize their product models. Smartwatch models that can replace the strap or allow to change the watch background are preferred.

Nowadays, most watch straps also allow users to wear them without being too cumbersome in the buckle. This is a huge plus compared to traditional watches. Kindly remember that comfort of use should be a priority.

Closing Points

To make your training more controlled and effective, investing in a good device is essential. The best fitness trackers for crossfit and weight lifting shared above can be a good start for you. However, if you still can’t find one you like, then you should re-read the buying guide to be able to choose the one that best suits your desires.
