Reading the heart rate is a key part of Crossfit.

It is critical that you make certain the watch comes with this feature/ function.

A good piece such as the Gamin’s Forerunner 735XT will deliver real-time readings via its legible display.

It also stores the data in the built-in memory for you to scrutinize later.

If you notice any anomaly, you can seek guidance from an expert.

Other than just showing your performance, you also have peace-of-mind since you can easily know if anything is wrong.

Battery Life

A good timepiece comes with a long-lasting battery.

It will keep a charge for many hours and this extends its usability.

The Fitbit Charge 3 has a battery life of 7 days.

And the Garmin Vivosmart HR can last as many as 5 days, while the Polar A370 has a duration of 4 days.

This means you won’t need to charge it every day or worry that it will shut off while using it.

Besides having a durable battery, a good choice will charge in a shorter time.

This proves helpful when you discover its low on charge and you need to use it within a short time.

Most good choices will have a decent charge within an hour.

Accuracy and Reliability

The last thing you desire when exercising is to get a false reading or erratic functioning.

Especially when you engage in dynamic activities such as trail or ultra running, biking & cycling, or Crossfit.

You may start worrying when you see your heart rate is too high or too low.

This may also affect your concentration or even make you stop altogether.

It is critical that you choose a piece that is accurate and reliable.

It will have a minimal margin of error and will work effectively and instantly.

You can adorn it on the wrist or pair it with a chest strap.

It should maintain top performance for a long time.

The Apple Series 4 is among the notable watches when it comes to accuracy.

Easy Pairing/Compatibility

Good HR watches allow you to pair then with other devices such as chest strap, and smartphone.

They also are compatible with apps.

This improves their functionality since you can look at the stored data later.

You also can use the information to set goals and targets.

With proper pairing, you will get functions like intensity, calories burned, distance covered, steps taken, HR and much more.

Apps such as Strava and DigiFit help in improving the workout and fitness.

They are easy to install and simple to use.


The workout takes place indoors as well as outdoors.

You will be using kettlebells, perform stretching exercises, hike, climb, run and much more.

You will also be exposed to the rain, sweat a lot, and drinking water or energy drinks may accidentally pour or spill on the watch.

It is therefore important to make certain the timepiece is waterproof.

The Garmin vívoactive 3 is among the best choices.

Besides being waterproof, a good unit is also weatherproof.
