HRM or other fitness technology?

i was looking into purchasing some time of watch or tracker...I like the idea of a HRM because it gives a more accurate calorie burn number than MFP.
but, I also like the idea of seeing how many steps I take in a day and see how much I burn all day.
But I have also heard issues with HRM's like Polar with issues of syncing/connecting as well as other technical problems.
Any suggestions? There are so many choices!

There are 8 billion MFP posts explaining why that isn't so.
Especially for walking....

A HRM would be more for activities vs all day wear though. So you can use both.
Everything is a guess and check. There is no easy way to say "today you burned x amount of caloires" and have it be spot on. Use a combination of tools and find what works for you if you want. I use a HRM successfully for activities people claim they can't possibly work for (HITT, etc).
Be consistent in how you measure and what you log. Do it for a few weeks. If you are losing weight than keep doing what you are doing.0 -

Based on " I use a HRM successfully for activities people claim they can't possibly work for (HITT, etc)" it seems you consider inaccurate numbers to be a success. No HRM can accurately estimate calories from HIIT (assuming what you're doing is actually HIIT, not merely interval training) due to the science behind the devices.0 -

Seriously, we are going to gripe about wording? I used a HRM as a tool in combination with other tools (like MFP) to successfully lose weight. Who gives a crap if the HRM is a few calories off? Your food labels are not 100% accurate. I made adjustments along the way to find what worked to successfully lose weight. Like I said in my original post: Everything is a guess and check.0 -

It isn't a gripe about wording. It is pointing out a claim (successful use of a HRM for HIIT calculation) that is wrong. There is a difference in the two. The SCIENCE behind HRMs is why they are inaccurate for things like HIIT (again, assuming what you did was actually HIIT). That SCIENCE applies to all HRMs and all users.0 -
There is a pretty significant difference between MFP's said calorie burns, compared to when I use a HRM. I use a Polar HRM, and it is the best money I've ever spent.0

I've also used my HRM to successfully lose weight while doing HIIT. The number it provides is ballpark enough of a number to work with. No one is saying it's 100% accurate. As she said above there is no true way of knowing the accurate number. The best we can do is ballpark. I compare my HRM number with MFP, and online calculators and my HRM is usually the lowest of the three. So I use that number. If I feel it's high I knock off another 20% or so to be safe. So yes what she is saying is correct. Even though the science behind the HRM isn't designed for HIIT you can successfully use it to lose weight if you are smart about it and understand that the number is ballpark.
For instance a round of Insanity Pure Cardio is 40 minutes. At my height, weight, and age I've had calculators tell me I've burned anywhere from 400-700 calories doing it. Even calculators geared for Insanity. MFP will tell me 400-450. My HRM is like 330-380. So I go with that number. I find MFP is consistently higher then my HRM.

Which is accurate, if either, largely depends on what activity you're doing.jlbrown1985 wrote: »What is the best inexpensive HRM?
For tracking HR data, any constant read HRM (either chest strap or newer optical such as Mio Alpha) works.
For calorie estimation, how close to accurate they come depends on what you do. They are not accurate for intervals (including HIIT), yoga, lifting, dance, walking, etc. For steady state cardio (running with gradual transitions or constant effort, rowing, steady cycling) they can approach accurate estimates. Most devices report gross, not net, calories expended.0 -

I don't know if it's the best but I use the Polar FT4 and I like it. Sometimes you can catch it on Amazon for less then $50 but typically around that price.

Losing weight is based on caloric deficit .. nothing more. Your HRM is inaccurate for HIIT (not that an activity you can do in intervals for 40 minutes is HIIT ... that is merely interval training). By your own admission you picked the lowest of the caloric burn estimates presented to you. Nowhere is there an analysis of which is correct ... if any is.
HIIT is exertion periods at over 95% of LTHR ... often exceeding 100% ... transitioning to anaerobic activity. Commercial HRMs, especially low end ones such as the FT4 and FT7, do not accurately estimate caloric burns from such activity ... just like they don't accurately estimate burns from yoga, lifting, low intensity activities like walking.0 -

Could you? Perhaps with enough trial and error you would eventually get there. But it wasn't working for me. I was using online calculators and looking at what other people were logging for similar activities and I was still way over estimating my cals burned. Wasn't until I got the HRM that I realized how much I was overestimating.

If you want to use a combo hrm and step counter then you need to get either the fitbit charge hr or fitbit surge. Sure they are a little pricey at $149 and $249 a piece but they work and work well. I use the Surge and an very satisfied, especially as it has an "app" where you can log either workout, yoga, pilates, spinning, walking, jogging, weights, circuit training, elliptical, and stairclimber (you choose which of 7 exercise you do most) and it logs it into your fitbit account. You have your myfitnesspal and fitbit accts linked and synced up and it logs everything. Hope this helps.0

I have a Polar FT4 HRM and I really like it, I've never had any problems with it. But it is only for actual exercise, not something to be worn all day. If you want to track steps and that kind of stuff for a whole day, you'd be better off with a FitBit or something similar.
That said, I don't trust the accuracy of a FibBit for monitoring all day calorie burn, they seem to overestimate a lot, based on the experience of friends and co-workers.0 -

Usually found in life that those 2 words don't go together - best and inexpensive.
My gym shirt that I don't care if it degrades in a month of washing being the exception perhaps.
Most chest HRM's are EKG accurate now - if all you want is a HR reading to base workout levels on for specific training.
That's not the interest of vast majority though.
Most want it for estimating calorie burn it seems.
A nice Polar that actually has self-test and required stats you can test and change is best for calorie burn.
The cheaper Polars, and lots of other cheaper HRM's, make some big assumptions to estimate those stats, and can be very off.
Though even the nicer Polar's can be too.
http://www.myfitnesspal.com/topics/show/459580-polar-hrm-calorie-burn-estimate-accuracy-study
Unless it's changed, cheapest Polar is the FT60 or FT80 or RS300X that has those stats.0 -

Again I understand what they were designed for and what they are accurate at tracking. But the way I am using it has allowed me to find semi decent ballpark numbers for me to work with doing HIT (home interval training) (Is that an acceptable acronym for Insanity??)

Or work out a really contrived way os stopping and starting it at arbitrary points in the activity, then only eating b ack a prtion of the calories logged anyway.
Plucking a number out of thin air does seem easier, but if one has spent the money on a toy then find a way to use it

Yes an HRM is a toy. And pausing it during the 6 minute stretching periods is definitely arbitrary. Couldn't possibly be common sense.
Picking a number out of thin air sounds much easier. I should have stayed with that method. Maybe would have lost half the weight I have currently lost using my toy.0 -

I'd just call it a workout DVD since HIIT kinda implies High Intensity Interval Training which I wouldn't think Insanity is.

I would say workout DVD is extremely obtuse but whatever not going to argue over semantics.0

The Garmin's can have their data uploaded into SportTracks and analyzed, and adjusted.
Once, I took an interval workout, and took the time to adjust the HR to get a better avg to use my personal VO2max calorie burn formula on.
So I figured that any increase in HR when I started sprinting would be offset by equal time drop, but the drop needed to come all the way down to normal HR when walking on the easy part, which normally doesn't happen in that short time span.
So the drop was made shorter to match the increase, and lower than it read to match normal walking HR level.
So of course with all those adjustments, the average HR was lower by 15-20 IIRC, which was a decent impact on calorie burn - if it had been a long workout.
But 10 intervals in 10 min, and after a 20 min slow cardio, another 5 intervals in 10 min, just didn't add up to much for only doing it every 3-4 the week.
Now, if attempting to do that 3 x weekly, perhaps a significant difference to take note of.
Then again, if I really attempted that 3 x weekly, I doubt I could have gotten the HR as high anyway, so the avg would have been truer without the adjustments, and the workout wouldn't have been as good anyway.0 -
I have a Polar ft7 and it's great for heart rate and calorie tracking for workouts. I have an additional strap for water workouts because I have a couple of pools that are salt water and the sensor gets corroded. I had some issues, but Polar replaced both the watch and the sensor with no hassle.
Not for steps, but I have a decent pedometer on my phone that doesn't nag me the way the Jawbone did: HealthyWalk. It's free, no log in, no hassle, no frills, no reporting to mfp or giving you a calorie count. Just steps - that's the basic physical activity you should do no matter what.
I may get an Apple watch, but it's not waterproof, so...0
