I use my hrm for every workout i do, now i walk home from work everyday at 5 miles an hour, the 1st few times i burnt about 200 cals now i do the 5 miles in 45 mins and it says i burnt 100 cals, i am confused because i am still walking as quick and still get a bug sweat on so how come there is such a big difference. Then tonight i walked 3 miles in 30 mins, same pace and i burnt 40 cals. I did 30 mins c25k going 2.5 miles the other week and it said i burnt 15 cals, which i found really odd!!!!! I have just bought new duracell batteries thinking mayb it was crap batteries that came with the hrm so its not that. Is there anything i can do or a way of walking that will burn more? The hrm has all my details stored correctly. :bigsmile:

It sounds defective to me. I would check with the manufacturer.

As you lose weight, your body carries less therefore it doesn't require as many calories to perform the action. Also, your body will adjust to the exercise and will decrease the amount of calories burned. Try increasing the level of difficulty for the workout. I started wearing wrist weights when I walk. It has helped a lot.

Something is very wrong. You should be burning around 100 cals per mile - especially if you can walk 12 minute miles - there is no way I could WALK that fast.

It definitely sounds defective!

Have you re-entered your weight or fitness level? make sure the contacts are wet so as to make good contact. i'm not sure as I have just bought one, but do they only count the aerobic heart rate? If so, are those settings correct, and is your heart working/beating less now?

If you use one that has a chest transmitter that you wear in addition to the watch, the transmitters go after a while and have to be replaced.

Make sure you are getting good skin contact with the transmitter. Use a gel or water to wet it before you begin, and have it tight enough to keep skin contact.

I'm guessing that you're just getting fitter :happy:

Remember, the fitter you get, the more you can do without over-exerting yourself. And just because you're sweating can just mean you've gotten a wee bit warm.

Does your HRM advise you for how long you were "inZone" i.e. supposedly burning fat? ... although we all know that's just wishful thinking :laugh: And do you record aveHR and maxHR?

It might be that your HRM only calculates calories based on your inZone time? :ohwell:

I sometimes get questionable readings on my Polar FT4, but then I check the inZone times and my ave&maxHR and then I think... well I probably didn't really do that much did I.

When I started cycling, I used to burn a lot of cals, but now I can do my circuit quicker and burn fewer cals because I'm a lot fitter and it's not such a struggle... plus I'm carrying quite a bit less weight now too :bigsmile:

Also, HRMs are only a guide to intensity of your workout... they're not 100% accurate 100% of the time.

Yep definitely seems to have a problem with it...No matter how much you lose no way should you get at 15cal burned...You get that from sitting down and standing up for 3 minutes....What kind is it or send it back or if inexpensive invest in another...

I'm assuming you meant 5 miles in an hour, not 5 miles an hour since the world record for a women's mile is just over 4 minutes, and I assume you're not training at that pace since you prolly wouldn't be worrying about an HRM and be on MFP.

But I'm still confused at you saying that you're walking 5 miles in 45 minutes. That's a 9 minute mile/6.6 MPH pace. And that's way beyond walking and most definitely into a running pace.

So, for a regular walk for 45 minutes, yes, anywhere from 100-200 seems totally normal depending on your fitness level, weight and speed.

But if you are running 6.6 MPH and going 5 miles in 45 minutes you should be burning in the 500 calories range.

right a big SORRY, i asked someone how many miles it was from work to my house it is not 5 miles like i was told before by someone else, i now know it is actually only 3 miles, so i do that in 45 mins. Ii doesnt solve my hrm querie but it does make me feel better as when i read all the comments that i must b either b exeptionally fit or running i questioned it coz i know i am walking very fast but im def not exeptionally fit or running. :blushing: :bigsmile:

Either way, your HRM is giving you the shaft on the amount of work you are doing. Get a new one....
