User-replaceable battery and simple operation make it a reliable companion for athletes seeking straightforward, effective heart rate monitoring without unnecessary extras. ## Description For those athletes who want basic heart rate functions - Indicates improving your fitness based on your heart rate in order to simplify your physical training. - Displays calories consumed - Includes a comfortable textile transmitter with coded transmission of your heart rate to avoid possible interference. - Suitable for swimming Review: I wasn't sure at first but this has helped me so much! - 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 desertcart 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. Review: Very useful, comfortable, easy to use - I have tried so many heart monitors, and none of them suited me. They either didn't work well, weren't comfortable, didn't have a continuous reading of my heart rate, which is important, or the chest strap was too big for my rib cage. I had heard good things about Polar, so I decided to try the FT4, and it works really well. The chest strap is really easy to put on, and I am able to get it tight around my chest. It does start slipping a little sometimes when I sweat a lot or move fast, but it does not seem to interfere with transmitting my heart rate. I either put electrode gel or water on it, and both seem to work well. The wrist monitor shows a continuous heart rate, and you can cycle through different screens to see calories burned, how long you've been working out, etc. I would have liked to have been able to set a maximum and minimum heart rate, so it could alert me if I went over or under either, but this model does not seem to have that. It is not a big deal, though, since I can just easily look at the screen if I'm worried my heart rate is getting too high. After your workout, it gives you a summary of the calories you burned, what your average heart rate was, what your maximum heart rate was, how long you were "in the zone," and so on. It is very, very helpful. I was not aware that I was burning so many calories at the gym because MyFitnessPal apparently thought I wasn't working out very hard and would estimate my calories at 200. I was actually burning way over that. This is very useful because I base my caloric intake on how much I burn. The only minor problem I have had with it is that in some yoga positions, it loses its signal. I don't really care, though. It's understandable that it loses its signal because I'm twisting myself into a pretzel. It also makes faint beeping noises sometimes. I have no idea why, but I figured out how to turn them off. If I am remembering correctly, if you press pause while it's in workout mode and press down (I think), you can go to the screen that lets you turn off the sounds. I'm very happy with my heart monitor, and it has proven incredibly useful. My husband bought the black one and has been very happy with his, as well. ## Features - Provides continuous, accurate heart rate to keep your fitness training simple - Smart Calorie feature uses your personal data to provide accurate calories burned - Includes heart rate chest strap made of soft fabric material that adapts to your body shape.

Just sitting down and turning it on?** A: I've never done that, but immediately starts registering my heart rate as soon as I put it on. So I don't see why it wouldn't work for that purpose. **Q: What are the main differences between the FT4 and FT7?** A: Hi Chelsea! Practically the 2 models have the same basic features heart rate monitor, what distinguishes FT 7 is that you can save the data on your computer or laptop through her polar site, and the other difference is that it has an option that is called "Energy pointer" that will determine the optimal intensity at which the maximum fat burning effect is achieved. In my opinion not much different from each other because I think they are very easy and convenient to use perfect for people who start training in any discipline or Gym with my personal training clients have always been a great tool to reach your goals . I hope you have served as something my humble response. blessings!!!! **Q: Do I need to buy the gel?** A: No, you do not. The watch comes with a strap that goes around your chest to monitor your heart rate. No gel is needed for this watch to work. **Q: What size strap comes with it?** A: This unit comes with the standard strap size; medium to xxl. This will fit 30 to 45 inches around. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I wasn't sure at first but this has helped me so much! *by J***R on May 29, 2013* 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.
