Best Overall

1. Garmin fenix 7

The Garmin fenix 7 has more than a sleek and durable design. It comes packed with features that make it a great fitness watch. It connects to the Garmin Strength + app or Garmin Cross Training. This makes it quite an asset when you’re doing Crossfit, as it has generic timers as well as timers that are customizable to Crossfit, like AMRAP.

The Garmin Cross Training app also comes with WODs, and you can customize them by using the app on the internet. This watch will track and save your Crossfit workouts, which means you can see your performance at a glance and how you can improve the next time you do something similar.

One of the features that will help you with your overall performance is the Pulse Ox, which monitors oxygen saturation in the body. This will let you know when to go all-out so you can achieve your personal best. It will also let you know when you need a rest day, so that you don’t overexert yourself, which could lead to injury.

If the tire flip is done outside, you’d still be able to track your performance as it features the “always-on” display which is still visible in sunlight. With advanced sleep monitoring, you’ll be able to track your recovery time, as well as make sure that you’re getting the right type and amount of sleep to perform at your best.


  • Can be used with Garmin Strength + or Garmin Cross Training
  • Pulse Oximeter (Pulse Ox)
  • Sunlight-readable display
  • Built-in feature for interval training


  • High-end features and style = high-end price

2. Polar Vantage V

When you’re working hard to achieve your fitness goals with Crossfit, you want to know that you have accurate stats at your fingertips, especially when it comes to monitoring your heart rate.

The Polar Vantage V uses Precision Prime sensor fusion technology to provide accurate heart rate reading. This allows you to train in your target fat-burning heart rate zone. Load Pro helps you monitor how strenuous the workout was, and which parts of the body were strained while exercising.

Before jumping into your next workout, you can check to see how well your body has recovered from the last training session. You can also use the Nightly Recharge option with this watch, which will let you see how you recover from all your daily activities.

Crossfit challenges you to beat your last performance, building strength and endurance and helping you to reach your peak physical fitness level. Connect the Forerunner 955 with the Garmin Connect app and you’ll be on your way to achieving your personal best.

It does have similar features to the fenix, but this watch features automatic rep counting, which comes in handy when completing an AMRAP. It’s like having a coach on your wrist that’s recording the statistics with every activity that you do, analyzing your performance and helping you improve.

The Garmin Elevate wrist heart rate monitor will keep you in your target heart rate zone while the PulseOx monitors your oxygen saturation, so you can remain at the top of your game.

This watch is designed to track all activity, and the Functional Fitness setting will track and store your heart rate from multiple workouts so you can track your progress and see where you’ve improved. The watch face will display the number of calories burned, how long the training session was and what your average heart rate was.

This will allow you to make adjustments to your workout, especially if you need to stay in your target heart zone. Apple has included the latest in their heart rate technology with this watch and you’re even able to take an ECG from your wrist.

Why is Crossfit good for runners?

Runners have very resilient legs, and this is because running works the hip flexors, quads, glutes, hamstrings and calf muscles, as well as activates and strengthens the core muscles. That doesn’t always equal physical strength, and often their upper bodies are less developed. This can lead to an imbalance in a runner’s body.

Crossfit is a full-body workout that uses functional movements performed at a high intensity to increase overall strength.

These functional movements are what you do throughout your day without giving much thought to it. They include things like squatting when you sit, and pulling and pushing movements like when you’re opening and closing the door.

Runners can benefit from the strength training that Crossfit offers, as it will help with your balance, coordination and endurance. It will also develop muscle, which will help support and strengthen the joints and tendons. This will lead to an increase in speed when you’re running, as well as a lower chance of becoming injured.

What features should a fitness watch have for Crossfit workouts?

When you’re looking at getting a fitness watch to help monitor and track your activity during Crossfit, there are a number of features that you want:

  • Different sports modes that include Crossfit.
  • An accurate heart rate monitor. When you lift weights in Crossfit in intervals, your heart rate will spike, unlike a runner’s which stays more or less even throughout their run.
  • You want it to monitor HIIT and Interval Training.
  • Crossfit has WODs – Workout Of the Day – and you want to be able to add the custom routine before starting.
  • Automatically detect the exercise and count the reps.
  • Personalization of exercises that can be added to the database.
  • Monitor and analyze your performance so that you know where you can improve.
  • It should tell you the amount of calories burned during the workout.
  • Flexible wristband that won’t restrict movements when powerlifting.
  • A visible display that’s durable and will hold up to the rigors of Crossfit.

What is Pulse OX?

The Pulse Ox (pulse oximeter) measures and monitors the oxygen saturation levels in your blood. This will let you know when to go all-out to achieve your personal best, or when to tackle that high-intensity interval. It will also let you know when to take a rest day, even if you feel like you don’t need it.

By monitoring your energy levels and oxygen levels, you’ll be able to maintain an effective oxygen level, which can improve speed, endurance and overall performance.
