Polar FT4 Heart Rate Monitor Review

The Polar FT4 heart rate monitor is one of the most popular heart rate monitor watches sold on Amazon. Over 300 people have reviewed this item and given it an average 4.4 star rating. That kind of rating is extremely good and when you read the reviews by some of the customers you will see what a great heart rate monitor this really is.

That is a very high rating and I encourage you to take a look at some of the reviews, as it can help you understand what people are using it for and how it is helping them. With a $70 price tag this is a very affordable heart rate monitor for anybody who is trying to analyse their exercise and workout sessions.

One of the great features of the Polar FT4 Heart Rate Monitor is that it can calculate your calories burned based on setting your own weight, height, age and gender. The built-in computer then calculates how many calories you have burned during each workout. This is great if you are targeting a certain level of calories burned, rather than just the time you exercise.

The in-box material includes the Polar heart rate sensor which is worn on the chest and secured using a chest strap. This allows for extremely accurate monitoring of your heart rate helping you to increase and decrease the intensity of a training session to optimize your performance.

The Polar FT4 falls into the entry level category of users who are looking to optimize and monitor their training. The most important features are included at a very reasonable price, but it will probably not be your best option if you are slightly more advanced in your training and looking to optimize your fitness level.

Once you set a target heart rate zone the watch will sound and display a warning when you are not in that zone. This really helps you focus on your training rather than having to constantly check your rate on the watch which can be distracting. After you finish training the watch will also display how long you spent in the heart rate zone and what you maximum and average rate were. This is great information to have about each workout as you will learn exactly what works and provides the best results.

Also of note is that it is water resistant up to 30m, which means that you can use the Polar FT4 heart rate monitor for swimming just as easily as for other out of the water exercises. Many other HRMs are not actually suitable for swimming, but having this features means that you can even use it for a triathlon.

Available in Pink/Purple or Bronze, so there is a choice in style for both men and women and comes with a 2 year manufacturer’s warranty.
