Great for training. Not only it constantly measures the BPM of the heart but it keeps track of the time out of the predifined range of BPM, its max and average. Calories lost on the session is a nice bonus

I love my polar ft4 ! It is so easy to use and perfect for tracking my workouts and progress on my weight loss journey. The only con I would say about the polar ft4 is that the training sounds are very very annoying so I turned those off! Other than that is is a wonderful product and I would recommend it to anyone. The chest strap doesn’t bother me at all like I thought it would, it’s just like an extra strap of your sports bra if that makes sense. I ordered mine in the super cute link color and I love it! I recently tried it out when swimming laps and it works like a dream in the water as well. Overall an awesome product and well worth the money.

I purchased the Polar FT4 Heart Rate Monitor Watch about a year ago after doing a lot of research on the countless fitness trackers out there on the market, and I rely heavily on Amazon reviews. I typically do not write reviews myself, but I have been so happy with this purchase I was compelled to share my support for this as well.
The ratings and reviews on this monitor are spot on. When I was looking for a fitness tracker I was taking a few things into consideration: truly reliable heart rate monitoring (running & lifting weights), calorie tracker, workout timer, and price. I was not concerned about a step counter, sleep tracker, and or a fancy app tracker to go along with it. Don’t get me wrong, those Fitbit watches are slick, but I personally didn’t really need all of that. Plus, I didn’t want a fitness watch to wear all day; I prefer to wear my other daily watches. Last thing about Fitbit, while they do have a good track record of accurate heart rate monitoring while walking/running, I’ve read that their watches do not track heart rate as well when doing strength training/lifting, which was personally a deal breaker for me.
My goal was to monitor my daily calorie intake to lose weight, so I paired this watch which tracks calories burned during workouts and the free Under Armour calorie counter app which tells you exactly how many calories are in the food/meals you eat. They worked amazing together. To date, I’m down 23 lbs. and I seriously don’t think I could have done it without this watch. It is so simple to use, and it provides instant gratification at the end of the workout to know exactly how many calories you’ve burned. One thing I’ve always struggled with while running/working out was the guessing game of how many calories I burned, did I really push myself as hard as I could, and constantly looking at the clock on the wall to figure out my rest time. This watch takes care of all of that.
The workout timer is also amazing because I like to do a lot of circuit training, so whenever I am done with a lift, I know exactly how much time I have to rest until the next set. Such a simple concept for a fitness watch, but Polar just makes it so easy, it’s amazing. No issues with batteries, malfunctioning, or anything like that either.
I could go on, but in all, I couldn’t be happier with this purchase. If you are looking for an easy to use, reliable, and functional heart rate monitor, then I can tell you this is it. Awesome job Polar, I think you’ve made a lifelong customer because of it. Good luck everyone!

Ce cardiofréquencemètre a un très bon rapport qualité/prix. La FC affichée est correcte. Je l’utilise depuis des semaines tous les jours. Il est paramétrable (poids, âge, sexe, taille) et réglable pour travailler dans un intervalle de % de FCmax déterminé. Quand la FC descend en dessous ou passe au-dessus de l’intervalle déterminé, la montre sonne, mais le son n’est pas énorme. En rapprochant la montre du capteur, elle affiche l’heure momentanément. Quand l’entraînement est terminé, la montre affiche le temps écoulé, les kcal perdues, le temps passé dans l’intervalle déterminé (zone), la moyennne de FC et la FCmax atteinte. Toutes ces données sont stockées en mémoire et peuvent être consultées facilement. La montre affiche également le cumul des données d’entraînement (total du nombre d’entraînement effectués, total des kcal brûlées, durée d’entraînement total). Placer la sangle avec le capteur au niveau du plexus est très facile et on en oublie la présence pourvu qu’on ne l’ait pas serrée trop fort. Normalement, il faut légèrement humidifier le partie du capteur qui est en contact avec la peau mais j’ai remarqué qu’il fonctionne parfaitement même quand on ne l’humidifie pas.
Je recommande ce produit.

I wasn’t sure about this, because I’ve never used a “heart rate monitor” before and I pictured something they’d hook you up to in a hospital. However, the good reviews here on Amazon sold me, and it wasn’t that expensive. Well, I couldn’t be happier. The strap isn’t bulky at ALL–I really do forget it’s there! I thought it was weird that you have to wet the “electrodes” before use, but I just literally rinse them for a second and then put it on. When I’m done working out, I immediately take the strap off, rinse it off thoroughly, and hang it to dry (after taking off the little monitor thing, of course). I’ve washed it a few times with gentle soap, as per the instructions.
This is exactly what I wanted for my fitness goals. I’m not a huge fitness nut, but I wanted to get healthier and lose some weight, and I hated estimating how many calories I was burning. Proof–on MyFitnessPal, which I use to track my activity and eating, it wanted to give me around 150 calories for a 51-minute I took with my dog today. However, this HRM said 350–because it picked up on the fact that most of it was uphill and I was going at a fast pace, hence burning more calories. I also like seeing my heart rate fluctuate because it motivates me to keep moving–not to let my dog sniff too much! I’ve always hated going up hills, and now I know why–my heart rate jumps at least 15 BPM when I’m going up a hard hill! But that’s how I burn so many calories (that and the brisk pace). So, I’m more motivated to go up hills because there’s an explicit pay off. It’s also very encouraging to look down and see how many calories you’re burning! And to know that it’s realistic and not something a computer comes up with.
I will say that the elliptical at the gym is pretty darn close to this thing, but it says I’m burning about 20 more calories than I really am at any given time. So I’ve burned, say, 250, but the elliptical says 270. Not a huge deal, but I like knowing it’s really 250 because I don’t want those 20 calories to make me go over my “budget” for the day.
Again, I was pretty skeptical with this, because I pictured it being really bulky and not accurate. But I find it’s very accurate, and very motivating! I also like that you can set up the heart rate goal so you know if you’re getting too low or high. This thing really encourages me to keep moving and to keep my heart rate up–which is just what I wanted! Very easy to use, too. A great purchase!
BONUS – I plan to try to start a family in the near future, and this will be great for monitoring my heartrate while walking, etc. so I don’t go over the safe limit. It’s just good to see where your heart rate is.

My husband has been using a heart rate monitor for a long time when working out and he loves it, says he would never want to work out without one. He advised me a long time ago to get one for myself, but it really wasn’t on the top of my to-do list.
Recently I started spinning, and using one of the provided heart rate monitors during the class. Since I’ve decided to keep spinning, since I love it, I wanted to get my own heart rate monitor so I could keep track of my workouts and not use ones that everyone else uses. I looked on Amazon for a Polar HRT and found this pink one that I absolutely love. I decided to pay a little more for the pink one since I’m pretty girly and it makes me feel cute when I wear it. (I know, sounds goofy, but true).
The shipping was fast, it came the first day of the three day period it said it could take to get to my house, which was great because it came in time for me to use it at my next spin class. I tried it out at home first, and it was easy to set up, comfortable to wear, and worked great 🙂 I notice I definitely have to get the sensors a little wet before using it so it works the best. I love how you can keep a record of your workouts in the watch, and it is perfect for me because it has a lot of little holes in the wrist band so it fits my little wrists, and could fit a large range of wrist sizes. Also, the band you wear around your body is adjustable and fits me, I’m a size 32 bra, so I was glad it was small enough for me also 🙂 It is easy to clean.
When I used it in the class, it worked great with the bike, and I was able to get a great workout and track my progress with the max and average heart rate totals/calories burned/workout time..etc. I’m excited to use it more and try it when I do other types of workouts & fitness classes. Thanks for a great product!!

Nach 1000 mal überlegen ob ich mir nun auch so ein Polar Uhr anschaffen soll, bin ich nun zu den Endschluss gekommen Sie mir doch zu besorgen und ich bereue es kein Stück.
Hält beim Schwitzen super und rutscht auch nicht runter.
Sehr gut!
immer wieder gerne!
