Best Fitness Tracker For Crossfit

As far as fitness trends are concerned, CrossFit has been on fire for the past years. From national competition to garage workouts, I also personally think that CrossFit is here to stay.

CrossFit is a good form of exercise and is based on the principles of high-intensity interval training. It gives you the best of both worlds, in terms of cardio training and strength. 

This high-intensity power fitness workout may include dynamic exercises, including Olympic weight lifting, plyometric jumping, explosive bodyweight movement, and kettlebells. These HIIT-based workouts have been shown to increase the body’s fat-burning ability and metabolic response. Thus, CrossFit can be an important part of reducing your belly fat.

Other benefits of CrossFit aside from burning calories are that it boosts strength, builds muscle, improves joint health, increases confidence, and supports your cardiovascular health.

So, if you’re serious about CrossFit even after the workout has stopped, you need to monitor your progress. To do that, you will need a good fitness tracker. 

In this article, I provide you a list of the best Fitness Tracker For Crossfit to learn everything you need to know before you buy.

What to Look for in the Best Fitness Tracker for Crossfit

Accurate Heart Rate Monitor

To better track your CrossFit performance, consider the fitness watches that have an accurate heart rate monitor. That way, you can adjust your energy output that will best match your heart rate.

Sports Modes

A lightweight fitness watch should have a multisport GPS function so the sport-specific features will empower you to train smarter for a certain activity. It can also allow you to add a custom routine even before you begin your workout or activity.

HIIT Option

It would be better if you can find a fitness watch that has a high-intensity interval training (HIIT) option for your cycles of intense exercises as well as short periods of recovery or rest. 

The Apple Watch Series 5, for instance, has optimized heart rate algorithms for HIIT so your activity stats are more accurate for CrossFit when using this option.

Battery Life

While no feature-packed fitness tracker may be able to last for weeks of use, at least you should be able to buy a watch that has decent battery life. Garmin Vivoactive, for instance, can go for up to 21 days in one single charge as long as you turn off the GPS.

Let’s Sum Things Up: Which One Should You Buy For Your Crossfit Workouts?

Fitness trackers and smartwatches are useful for CrossFit. But still, you need to invest in the right fitness tracker so that you get your money’s worth. If you ask me what my top pick in this list would be, then it is the Garmin Fenix 6.

I consider it as the best fitness watch on this list because you can follow custom workouts, specifically for CrossFit. Also, it has a good interval feature like the Suunto Spartan Sport so you can set various timers and have work and rest periods.
