Boost Your Training With The New Fitbit product.

The long-awaited Fitbit Charge HR fitness tracker is released at last and it proves to be one of 2015’s most interesting fitness gadgets so far. Fitbit has a long and popular row of training gadgets with the Zip, One, Flex, and Charge, but this is the first one with its own integrated heart rate sensor.

Update 2018: Read about the brand new Fitbit Ionic here.

The previously mentioned devices are all motivational tools that in the end will help you in the often long way of getting in shape and increase your health. The Fitbit Charge HR is especially good at tracking your daily activity statistics and is maybe the best on the market today.

The updated HR version of the Charge is supposed to be worn by more serious athletes, but can of course also be used for normal people. Experienced trainers will find that a gadget like this is perfect for checking their progress.

Heart Rate Sensor inside

The large news with this version is, as you might have guessed, the optical heart rate sensor which constantly measures your pulse. The system is called PurePulse and a couple of LEDs on the inside of the band lights on your skin and the reflected light can be interpreted by the sensor to figure out how fast your heart pumps blood through your body.

A heart rate sensor is alpha and omega for maximum training efficiency. I have written an article about why you should track your pulse and workout in heart rate zones. You can read the article here or click the link below. This is equally important if your goal is to burn fat or boost your cardio health.

Maximum Heart Rate and Training Zones


Even if the heart rate sensor is the most interesting and important feature on this fitness gadget compared to others, it contains all the features the Charge (without HR) and similar units has had. It has sleep monitor which means you can wear the band twenty-four hours a day – expect when charging.

The activity tracker monitors your daily steps, distance, calories burned and flight of stairs. It tells you the time and has a stop watch function when you hold the button.

Exercising with the Charge HR

This gadget is perfect for athletes.

The fitness tracker has two modes which are Workout mode and All Day Activity mode. The first one tracks current workouts and the second the whole day of activity. All the data, even if it’s your sleep hours or training statistics, are automatically synced to your smartphone or tablet where it’s presented with illustrative graphs that are easy to interpret.

When paired up with a smartphone you’ll see call notifications, Caller ID, on the display on the wristband. This only works if your phone is nearby the Fitbit Charge HR band but is a neat feature that allows you to take a quick look at your wrist when the phone rings, and you’re in a running session. If it’s someone important, you can decide if you should take it or not.

At night, the band will automatically monitor your sleep and check how many hours you had good, deep sleep. In the morning, it wakes you up with a silent vibrating alarm which wakens only you at a chosen time. I have yet to discover that sleep monitoring is really helpful, but I tend to use it to see how many times my one-year-old daughter is up each night.


The fitness band is made of a sturdy rubber-like material with a nice original look. It comes in 4 colors which are black, purple, blue and orange. They call the purple color Plum and orange color Tangerine. Some colors were unavailable when this article was written. The grooves don’t gather much dust even if the surface isn’t smooth.

It is light weight and very comfortable to wear which is important on a wristband designed to be used all day around. It comes in two sizes, Small and Large so be sure to get the correct one for you.

It has a new metal latch design which is totally secure and an upgrade from the original Charge. This HR version has a pin entering a hole in a way which makes it impossible to lose the wearable, much like ordinary clocks.

The band has a small OLED display which gives you the information you need. Clicking the button on the side will show you in the time, your steps, real-time heart rate, distance, estimated calories burned and flight of stairs. The idle clock function works great and it’s possible to tweak a bit how the watch looks with different fonts.

Is it waterproof?

The answer may disappoint you, but it probably doesn’t matter if you aren’t planning to buy an activity tracker for swimming. For some reason, Fitbit hasn’t rated the tracker as really waterproof, but it is water resistant to 1 ATM.

Usually, on these gadgets, it has something to do with the optical heart rate sensors which are more open to the environments. It is supposed to handle rain, but make sure you remove it from your wrist when entering the shower or pool. It was the same thing with the Withings Pulse O2 Activity Tracker.

If you need a waterproof activity tracker for swimming, I can recommend the TomTom Multi-Sport Cardio GPS Watch.

Sync it to the easy-to-use Fitbit app

It’s necessary to install the easy-to-use Fitbit app on a smartphone or tablet you use daily. I addition to viewing the collected data with nice illustrative graphics and graphs, you can share results with your friends and community and compete with others. If you get the routine to log food in the app, you will get an accurate estimate of calories burned.

The rest of your statistics are easily lined up on the screen and present a great overview of your training. Fitbit is well known for having an app which is very easy to use.

When your personal goals are reached, you’ll get awarded with badges in the app which is surely very motivational.

The battery life is quite long and lasts for seven days. I would say that’s above average. According to Fitbit themselves, they are safe and estimates it to be around 5+ days. It takes around an hour to charge it up again with a cable put into a USB charger or PC.

This is a fitness tracker which does a great job measuring your whole day activity. The heart rate sensor works well for running and training.
