HRM vs. FitBit

I'd get an HRM, one with a chest strap. Check for apps on Play Store that you find interesting to check for wireless compatibility.

I have searched around quite a lot and asked opinions to friends on MFP with HRM, and most pointed towards Polar HRMs so far, whether they use one and they like it, or use another brand and wish they got a Polar instead. I am getting mine only at the end of May, so I don't know yet.

The FitBit seems to be quite useless in comparison. It counts things that you don't really want to count (like walking around/sitting at works calories) and doesn't have enough features it seems when it comes to actual workouts.

Good luck!

HRM polar f4 with a chest strap, paid about $65 with free shipping, I love mine.

I would get a heart rate monitor. I have both, and the Fitbit is fun and provides some monitoring especially since I'm recovering from an injury and can't be active. But for an active person who is going to the gym and has access to treadmills, ellipticals, bikes or who may want to run outdoors, you will get more bang for your buck from a HRM. It's important to know how hard you're working during exercise. If you do interval work, it's even important.

I have a low-level Polar with a chest strap. I suggest getting something simple like that. If you like it, you can always get a more sophisticated model later on.

It depends on what you really want.

Personally, I don't trust HRMs for accuracy, nor do I really trust the FitBit. I spent a lot of time considering them but they didn't meet the needs I was looking to fulfill.

I went with the BodyMedia Fit Link. Why? Because it monitors at a study proven 90% rate for your entire day. You wear it all day long, and it measures your personal burns, activity, steps, and determines quality of sleep. It gives you goals based on YOUR numbers after you wear it for a few days.
The problem with the other two is that though you might be able to put in age, weight, height, etc etc, they still base their calculations on the average rate of burn for those statistics. The BodyMedia/BodyBugg device monitors all day and "learns" your average day, and bases your calorie goals on that. It calculates on what happens with YOU, not what happens with the average.

Things I've learned through wearing it... I sleep rougher than I thought I did. I burn less than what MFP calculates as my BMR, but more than the calculated TDEE. I figured out that for what I do every day, I was still undereating. The Fit Link syncs with a smart phone, so you don't have to wear a watch, and gives you a by the minute burn, deficit, and step count.

It *is* more expensive, but I swear, I don't regret any penny spent... Not on the device, nor the subscription fee. I was plateaued, and within 2 weeks of using it, dropped almost 5 pounds and continued logging a little over a pound every few days.

That being said, if you only want a general idea of your exercise burn, the HRM will do that, but I worry about their accuracy for so many reasons... blood pressure, heart rate, positioning... it all can change what that device reports back. You can't wear it all day, and not all models give you a chance to measure your RHR, which is vital to measuring the exertion you have during the work out.

To add: The phone app for Android works very smoothly with my device, and gives you a way to monitor work outs specifically so you know what is "extra". I love being able to set it to an open work out and see my calories, steps, and activity intensity in real time.

I have a Polar FT4 and absolutely love it. It's pretty much the basic model of the Polars and very easy to use. And it does exactly what you're wanting. It cost me @ $70 with shipping. The only issue I have is it's not waterproof. My next one will be waterproof so I can take it in the pool with me. Totally get a HRM.

FYI PolarF4 does go in the pool and the product manual supports that. It says don't press the buttons in the water. I've used it the pool about 6 times. Unless the chest strap is REALLY tight, though, it loses the heart beat.

I actually got my FitBit first. This was because I was in much the same situation as you sound. I had very little desire to do cardio and needed to start somewhere. I'll be honest and tell you that I was very skeptical about the FitBit when DW first mentioned getting one, because I didn't really think that it would do anything. Boy was I wrong. Within a week of getting my FitBit it showed me that I was actually not as active as I had thought. That got me moving. FitBit also has what it calls "Badges" that are basically achievements for doing certain things, some badges are daily goals and others are lifetime achievements. That more than anything got me going at first because I am a gamer--not only that, but I am a completionist gamer. In case you aren't familiar with that term, it means I spend hours and hours on a game trying to discover every secret, unlock every achievement, follow every sidequest, etc..

I also want to mention a misconception that I read someone writing earlier in the thread: He stated that the FitBit measures activities like sitting/laying/etc. it actually does not. When you set up your FitBit profile, it figures out your BMR and then every five minutes, it updates your Calories burned for the day. This means that it will give you a fairly accurate idea of your TDEE if all you do is walk/run/sit/sleep. It does have a harder time tracking some cardio exercises and anything that you are doing with your upper body, but that is where a HRM comes into play. Now, the integration with MFP is really where the FitBit excels, IMHO. Every time MFP syncs with FitBit, it updates your exercise Calories based on both your MFP activity level AND your actual (FitBit-recorded) activity.

I have since gotten a HRM (a Polar FT-40) and have started doing Power 90. During which I use my HRM, but my FitBit stays on me day and night. The only time it comes off is when I am showering (I put it on to charge at that point) or when DW and I are, erm, doing our taxes...

The bottom line is that I love my FitBit and I think that it more than anything has helped me to get motivated to do stuff. I love my HRM as well, but I love it because it gives me accurate data and helps MFP to motivate me. The HRM by itself isn't a huge motivator. I cannot recommend the FitBit as a first purchase more. Hope this helps.

My primary exercise is walking.
I have a Fitbit and it is very easy to use, keeping it all day long.

Using a HRM (I used to use a Polar while running with a cardio watch) is more constraining.
Fitbit does not track gym exercises or treadmills, but these can be declared as exercises or Fitbit can be linked with another site that is tracking them. I am not using any of those.

The fit bit is great, but if you aren't into doing a bunch of cardio, and want to see what you are burning for calories while lifting then the polars are a better way to go.

I have used a Jawbone Up, a Fitbit, and a heart rate monitor. I find that the Fitbit can work great for just walking, and it will monitor your sleep as well, if you're interested in that. I work off a Mac, so I sometimes have to reset to get it to sync properly, and I'm really annoyed that I can't get it to sync to my iphone, but need an actual computer to plug the base station in to. That being said, it is otherwise a pretty good product.

What it doesn't do well is monitor the following exercises I am also engaged in: exercycling, bicycling, karate, kobudo, and Zumba, due to the relative lack of steps to calories burned, and the use of the upper body in these activities. I also find it overestimates just how fit I am and underestimates my calorie burn when I'm running. It's great for calculating extraneous calories burned when running around stores and visiting NYC.

I have a Garmin chest strap that I've used with my Oregon on my bicycle. Haven't figured out how to get the calorie burn from it yet. Mostly, I've been using a Timex Ironman triathlon HRM that I got on Amazon. It's done a fine job and watch is stylin', or at least more stylin' than the polar watches. What I would recommend is getting a HRM with a soft chest strap, because the harder plastic can chafe the soft bits that hang around in the area you put your strap on.

If you get a digifit for your Iphone, you can use the Digifit app with your HRM as well. I have just checked this evening, and you can dual record on dgifit and your regular HRM, which is a hoot. Most of the chest straps use the same ANT+ protocol and will work with multiple products.

If you are only going to get one and don't care to count calories shopping, I'd get the HRM.
