Advice on calories burned

belanna5

I'm 38, 5'4 ft, 127 lbs. I'm 6 lbs away from my goal and untill now I didn't log all my activities because I didn't think it was worth it, it wasn't accurate and I wasn't going to eat them anyway. But now that I'm raising my calories intake I feel the need to know how much I'm burning. So I bought a HRM, a Cardio ONRHYTHM 310 ACCESS, not the best but at least it allows me to set weight, age etc...
I used it for the first time today and at the end of my work out it read 651 cal. It seems a little bit too much. This is what I did

10 min. elliptical
abs: 3 series of 20 upper, 20 lower, 20 lateral, 20 upper
leg raise: 4 series for each leg: 30 lateral, 30 internal, 30 back, 30 lateral
leg curl, 3 series for each leg 25 repetitions
45 min fast walking (7 km/h)
total 1 h and 37 minutes

To all fitness experts out there:
Do you think 650 is a realistic number or how much is it far from reality?
Thanks

I'll give it my best guess? I burn 667 calories with 60 minutes of kickboxing/Tae kwon Do. It's a VERY intense workout. I almost always lose weight when I do it. I'm also bigger than you are at 5' 9" 149lbs so I burn more calories. My calorie counter doesn't recognize my weight lifting at all. IMHO it sounds way over for 10 elliptical and 45 at a fast walk but I could be wrong.

Seems a bit high to me, but it is mainly where you got and kept your heart rate.

Does your new HRM show you your average HR? What about how long you were in a particular zone?

Google HR to calories and you can enter that information to see how close the HRM calculation was.

That's what I was thinking too.

It's not really weight lifting, more mat excercise.

Honestly couldn't tell ya. You're probably going to hear that a HRM isn't meant to track anything other than steady cardio. That being said, you'll probably also hear that the number you gave is inflated because it included exercises other than steady cardio.

The calorie burn really depends on the person's level of fitness and effort more than just the activity and time.

Edited because I can't spell.

HRMs aren't really intended to calculate calories during strength training, just cardio. I'd think you probably burned 350 for the cardio. Then maybe give yourself another 100-200 for the strength since you did it for so long.

So I'd say eat back at least 400, maybe 500. From now on, just use the HRM for the cardio and see what it gives you.

Yes, it does, it says a was 53 min and 26 sec 'in zone', average hr 131, max hr 161 (I did jog for ten minutes). What does it mean? Help!

Using the details you provided, this website (just the first one that came up with the search) http://www.shapesense.com/fitness-exercise/calculators/heart-rate-based-calorie-burn-calculator.aspx gives a number of 431 calories during that duration with that average HR.

So, I would look at the numbers you entered when you set up the HRM to see if you mis-entered something and if not, then I would not use the actual calculation of the calories burned.

Thanks, I think I'll use it only for cardio from now. And I adjusted the calories I logged today.
