Best Smartwatches for Crossfit Training: Top Choices Chosen by Elite Crossfitters

Crossfit has taken the world by storm in recent years, and for a good reason too.

It’s a rare fitness activity that can help build muscle while also being an intense cardio workout.

It also helps with losing extra weight, and it can be optimized with a watch with a fitness tracker feature.

And with all the choices out there, finding the right tracker might be a challenge.

But, to help you, we’ve narrowed it down to the following best born-for-Crossfit fitness trackers below.

Let’s check them out.

Which Watch Has the Most Accurate Heart Rate Monitor?

This question has been argued for a while, and the answer lists are not the same every time.

However, among various articles, there are some common names that they all agree on.

The names include Garmin Forerunner 245 Music, Garmin Forerunner 945, Apple Watch Series 4, Fitbit Ionic, and Samsung Gear Sport.

However, the accuracy of each watch also depends on the type of activities you usually do.

Some are perfect for measuring heart rate during light workouts, while others are better for running and biking.

Eventually, you should still do your own research to find the fitness watch suiting you best.

Are Fitness Watches Accurate?

Experts have confirmed that fitness watches are generally accurate for common purposes.

But they also add that the levels of accuracy still vary according to what you want to measure and what kind of watch you use.

Often, most watches provide reliable step counts and heart-rate data.

However, heart rate during intensive exercise and calories burnt are more tricky, to be exact.

As mentioned in the previous question, it is also a matter of choosing the right watch to fit your goals.

What To Look For When Buying A Workout Watch for Crossfit

best watches for crossfit


This is by far one of the most important things to consider when making your purchase.

You don’t want to have a watch that feels uncomfortable and inhibits your movement when you’re working out.

So it would be best to get the smaller watches that can’t really be felt when worn and to find a strap that won’t slip off your wrist or arm (depending on where you wear the tracker).

For this, you can check out these Polar watches.

They’re really great ones.

Heart-Rate Monitor

While distance and steps taken are great stats, your heart rate and the number of calories burned are of utmost importance when doing Crossfit.

Your heart rate will increase and decrease throughout your workout, and understanding when that happens with a good HR watch can really show you where you can improve and have an even more efficient workout.

Battery Life

Imagine wearing your watch throughout the entire day, and when you go for a Crossfit workout before heading home, you realize that your watch is out of battery and you can’t use it for training.

That would suck, and you would most likely feel really frustrated.

To counter this, look for watches that can actually be worn the whole day without the battery running out.

For those who end their day with a workout, a watch with long battery life wouldn’t just be beneficial but necessary.

Personal Preference

You can read all the articles and reviews you want at the end of the day, but the choice will always be yours.

From the colorway, the features, and the materials you want in a watch, it’s all up to you.

However, it’s still very important to really think about the purchase through, as getting a good fitness tracker will help you become healthier.

There is no “wrong” choice as long as you feel good and confident in the decision you made.

But in case you’re still wondering about which brand to go for, then check out Suunto and G-Shock watches.


What is a CrossFit workout?

CrossFit is a type of HIIT, meaning High-Intensity Interval Training.

It focuses on strength and conditioning workouts composed of intensive body movements. 

There are different levels and variations among CrossFit classes.

However, most CrossFit lessons have from 3 to 4 sections.

First of all, the trainer will introduce a dynamic warm-up.

Then, you will start to focus on strength training, such as deadlifts or squats.

Finally, everyone can enjoy a cool-down and stretch.

CrossFit is highly effective because it puts people on heavy and high-speed training.

That also makes it a challenging workout.

Therefore, it is recommended that you get professional direction first when starting to exercise CrossFit.

Who should not do CrossFit?

There are so many variations of CrossFit focusing on different purposes that almost everyone can enjoy its benefits.

Even old people or people with minor injuries can choose a suitable class based on their condition.

However, a few people may not fit the training, such as patients with doctors’ special guidance, athletes, and solo gamers.

A CrossFit athlete or may need another specific set of training that suits his or her goals.

Besides, some people simply operate better when being alone.

Since CrossFit is about groups and community, extreme introverts may not find it too amusing.

It is best to know yourself and choose what your mind and body need.

Is CrossFit good for losing weight?

There are so many factors concerning losing weight, including your metabolism, calorie intake, and habits.

Yes, CrossFit can help you  shred a considerable amount of calories which is good for losing weight.

However, it is necessary to keep in mind that no matter how hard you train, if your calorie intake is too high, there is no way to beat that.

We should also make it clear that CrossFit is not all about losing weight.

It is more about making people healthier and stronger both physically and mentally.

Is cross-training CrossFit?

No, their names can be confusing, but they are not one.

Cross-training is simply a combination of various exercise methods in one routine.

For example, for the first 30 mins in the gym, you do a kind of cardio like running.

Then, you changed to weight lifting in the last 30 mins.

Both types of training are beneficial, but they are not the same.

Cross-training is more individualistic and focuses on boosting endurance.

Meanwhile, CrossFit is specially designed to push people to their limits while building a community of supporting members.

Is Garmin better than Fitbit?

Both Garmin and Fitbit have diverse models serving many fitness needs.

Among these models, there are equal pros and cons.

Consequently, which brand to choose depends on your needs.

On the one hand, if you want something clear, easy to use, and that focuses on your daily activity, Fitbit is a good choice.

On the other hand, if you want to go more into details and have advanced features, then go with Garmin.

It is all about what is more suitable for you.

Do people wear Apple Watches to CrossFit?

Yes, in fact, Apple Watches can be your best workout partner during a CrossFit session.

The watches can tell you not only about your body’s conditions and your workout movements but also about the environment surrounding you.

As a result, you can better alter those conditions and have the most effective workouts.

What are the best apps for CrossFit training?

Again, there is not about the best app fitting all but about which one is for you.

If you just started out and need a detailed guide on every move, then WODs CrossFit is a good choice.

If you care more about tracking your result and challenging yourself, check out the 30 Day Fitness Challenge, WodLog, and Trifecta.

For people who are into competitions, apps like Beyond the Whiteboard and WODBook let you compare your achievement with other members.

Furthermore, these are great apps with advanced features, including extra advice and nutrition tracking.

What is a good resting heart rate by age?

From birth to 10 years old, human’s heart rates fluctuate from 70 to 190.

It gets slower and slower as we age.

By the time we are over 10 years old, a normal resting heart rate is between 60 and 100 beats a minute.

Professional athletes can have their normal heart rate below 60 bpm and still live healthily.
