    I just got my FT4 today. One question, can you use the chest strap in the pool or is it just the watch that is water resistant?

    why not? It's only like $30. Instead of going out for dinner, spend the moolah on a HRM :)

    YES,YES,YES!
    Bought Polar F6 Months ago the BEST motivation EVER!!!! It makes me excercise everyday and if I dont I feel totally guilty. No more guessing! You need 1 w/ the chest strap as some1 stated previously! Check Ebay, you can get for a lil cheaper...
    Good Luck!

    Wow, you're going against the grain, here, but I'm with you. I don't have a HRM, but you make sense that they are both an estimate based upon the average. I've been losing weight at the MFP rate by following the MFP calorie plan. So, tell me why, again, I need to spend $100-200 on a HRM? I'd rather spend it on HEALTHY food I REALLY LIKE.

    "A heart rate monitor consists of two parts - a transmitter attached to a belt worn around the chest, and a receiver worn on the wrist like a watch.

    As the heart beats, an electrical signal is transmitted through the heart muscle in order for it to contract. This electrical activity can be detected through the skin. The transmitter part of the heart rate monitor is placed on the skin around the area that the heart is beating, and picks up this signal. The transmitter then sends an electromagnetic signal containing heart rate data to the wrist receiver which displays the heart rate."

    That's copied from a another site, but it shows that a heart rate monitor is not just estimating. You have to put in your age, weight, height, and ideally your max heart rate... those things, combined with the electrical signal combine to give quite an accurate account of your calories burned.

    another good thing about an hrm is that you can actually see yourself getting fitter via your average heart rate and calorie burn. In just 5 weeks, I have to do half again as much work and distance on my bike to burn the same number of calories. And, the hills that used to make my heart rate spike to 186 I now barely get to 177 on, if I'm pushing hard. Which encourages me to work harder. If I didn't have a hrm, I would never know this, and probably would not be improving so rapidly.

    It's a great way to monitor your progress.

    Of course, if you are losing weight and feeling good without one, there's no real NEED to get one. :)~

    It may not be not estimating your heart rate, but it uses your accurate heart rate reading and all the other info you feed it to estimate your calories burned. It's a very educated estimate, but it's still an estimate, or at least that's my understanding.

    Those are more great reasons it could be a useful tool. Still, it's a tool that sits in my dresser drawer. :tongue:

    yep, you can wear them in the pool.

    i have a polar (don't know the model) but it's fab. i feel like i use it well and pay attention to it, although because i run i don't often stay within the heart rate limits (mine has 3- light exercise, moderate exercise and hard). it's fab to keep track of how you're doing, and i find it motivational just to make sure i don't have too many gaps in my training days (the watch actually memorises the last 14 exercises, and i get a message on it every sunday how many cals i've burned and how much time i've spent working out over the week).

    and if you're larger, the band works well over the top of your boobs (i tried to put mine under, but the strap rode up to underneath my bra and was very uncomfortable.)

    For the people with HRM... do you subtract your BMR from the total number of calories? I saw a thread on this the other day.

    Anyone? I've been thinking about getting a HRm, but I want to make sure I will be recording my burned calories correct! Help!

    yes, I subtract 1 cal per minute. So if I run for 45 minutes and burn 320 cal, I only log and eat back 275, since I would have burned about 45 laying on the couch, which is what I would have been doing had I not been running!

    Polar does NOT take those cals into consideration, the polar people have confirmed this, you DO need to subtract them out if you want it to be close to accurate.

    Can you share where Polar has confirmed that? I've contacted customer support directly and been told that they do not discuss the specifics of their calorie estimation algorithm because it's confidential and proprietary... If they've gone on record as saying that I'd love to know where.

    Having said that, my personal belief is that they USED TO deduct the RMR calories in earlier generations of their products (my F55 for example) but do not in the current crop (my FT60 for example) - I believe this because doing the same workout at very similar intensity (P90X Cardio X for example) will show a value about 150 calories lower on the F55 than the FT60 - which is very close to my 60 minute RMR (Resting NOT Basal Metabolic Rate).

    Since switching to the new generation Polar HRM, I have indeed started deducting what I would have burned sitting on the couch... so put me down in the "does deduct" category, and also count my vote as a "yay" for picking up an HRM - I can't imagine going back to pre-HRM days, but I'm also a bit of a numbers geek.

    I have a Polar FT7 and I love it, it was worth every penny! My only regret is not getting one with GPS (WAY out of my price range!), but maybe in the future!

    Yes, I do subtract my BMR from the calories burned during exercise.

    Not to sound like a Polar/Best Buy shill or anything, but Bestbuy.com has had the Polar FT60 with GPS receiver on sale for $180 for the past month, down from $330, basically a free GPS unit with the FT60 at normal price. If I were in the market for a new HRM it's what I'd be buying.

    Just sort of playing devil's advocate... people have been able to become extremely fit for thousands of years without the use of HRM's or calorie counting, or any sort of technology whatsoever. When I first started this journey, I never did any cal counting, never had an HRM, and still, I lost the majority of my weight in those low-tech days.

    But then somehow I found my way to MFP, and so did you. So I guess some part of you is interested in data tracking, otherwise you probably wouldn't be here. An HRM can help you be a little more accurate with tracking your cardio burns. If this sounds appealing, then go for it.

    Warning: may lead to OCD logging behavior.... :)

    i love my HRM and agree with everyone's reasons in support of it. i can testify it does encourage OCD behavior as i'm now the type to subtract BMR calories from my HRM reading. :) however, i also think that you can lose weight fine without one - you've already more than halfway to your target weight, so you're making great progress.

    plus, what's much much more important than being accurate with exercise calories is being accurate with food calories. i've seen it on here that weight loss is 80% diet, 20% exercise. i would agree with that (and i'd toss in your body's metabolism as another factor).

    mfp definitely overestimates my calories burned, but given that i burn 300-400 calories an hour, it's off by ~150 calories. in comparison, it is soooo easy to underestimate how many calories we're eating. 150 calories is equivalent to a 1-2 tbls olive oil, half of an avocado, a handful of almonds, etc. it's effortless to undo any exercise calories with a snack here or there. it's more critical to watch what you eat, in my opinion.

    so if you must choose something to be OCD about, i'd strongly recommend a kitchen scale. :) i would say it's the best weight loss tool i've invested in (with my HRM being #2), and it's a lot less expensive than a HRM.

    I just tried out my new Polar FT4 and love it. I did a very brisk 3 mile walk and was able to keep my heart rate in my target zone and do some interval walking. My calories burned were 368 and MFP estimated 381 so not too far off but I'm glad to have it personalized to my height, weight, etc.:bigsmile:

    The chest strap was very comfortable and hardly noticeable. Very easy to set up the monitor also. Highly recommend from me!
