Did I really burn that many calories???

i totally feel the same way... but who knows, i don't have a HRM yet either so I'm never sure!

Today, was my at home workout. I ended up doing about 25 minutes of the Cardio Excercise on the Liverexercise.com website. I admit I was doing it at a slow pace, since it my first cardio workout in a while. I usually do the treadmill at the gym. Most of my reps was between 5 to 10 and I was sweating quite a bit (my clothes were damp afterwards) AND I'm sore right now. When I logged in my Exercise Diary, it showed 441 calories burned for Aerobics, low impact @ 25 mintues. Really?!?!? I burned that much?!?!?

Ok, I'm a big girl, considered obese. I know MFP figures in my weight when calculating calories burned, so should I just accept that I really burned 441 cals? Do I assume that I'm burning more because I weigh more than the average weight person and I have more to burn. Don't get me wrong. I'm super psyched if I did burn that many, I guess it's hard to believe it.

FYI: I don't own a HRM yet, but I plan to do so within the next 1 month or so. I know that will help alot.

Does anybody feel the same way about some of the calories burned numbers or is it just me?

Hey,
I would recommend you this site I am following this instead and when entering what exercise I did during the day I just adjust the calories accordingly.
Hope it helps.

I think the estimates are on the high side also I use the body bug and its pretty accurate so I try to go by the numbers from it.

I don't have a HRM yet either, so I'm kinda in the same boat with you on not knowing how much I burn exercising. I think the more you weigh, the more 'off' MFP's calculator is. I personally weigh 257... I use the elliptical machines at the gym which have HRM...yesterday I did 35 min, maintaining 4.8-6.2 mph (best for me yet) and the machine said I burned 451 calories. I entered my info on MFP's calculator and it said 610 calories.
So I agree that until you get a HRM, it's better to underestimate your calories burned than to overestimate.
Keep up the great work!

So if the treadmill at the gym calculates calories burned based on weight entered and heart rate then I should believe it and not the MFP calculation?

I just don't know about this burning calorie business - everybody says MFP overestimates calories but my chest strap HRM ALWAYS gives me more! It depends on how your heart works - if it stays high you will burn more than low. Good workout regardless - well done!

MFP is an estimate.
HRM's are estimates.
Bodybuggs are estimates.

For simplicity sake, take whatever the lower number is.

If you don't have a HRM or bodybugg then I would do as suggested and don't eat back all of your calories just to be conservative.

100 burpies in 7 mins 49!!!! very impressive!

I felt like I was about to cough up a lung afterwards though :P

Why why why does everybody on here think that heart rate monitors are calorie counters???

All a HRM is designed to do is monitor your heart rate.

The only real way to judge how many calories you burn doing something is via expelled gas analysis.

If you want an estimate, use the numbers here or on another similar website, they'll be just as accurate as any HRM.

ditto this.

I don't get the HRM thing for calories. Just make sure any calorie counting devise takes into consideration your BMR (The amount of calories your body burns during rest).

I bought my HRM about a month in and I have found on something I burned more than what MFP estimated on a few activities I'd burn less. But being bigger does make you burn more. I've seen it in just the past 3 months of me getting in shape. I don't burn as many calories as I use to. The one down fall of losing weight;) when you weigh more you get to eat more and during exercise you burn more calories then you do when you start losing a good amount of weight.

I do realize HRM's are estimates, but to me I feel like since in detects my heart rate from the chest strap and has me put in my height, weight, finds my BMR before I exercise, its more accurate than the calculators I have used on the web. Alot of calculators I have used will give you the same number of calories burned as anyone in your BMI range- which people could be 40 lbs less than someone else and get the same calories burned. I'm not sure how MFP calculates it though. I only wear my HRM during exercise and not all day long. But I like it to because I can keep track of my heart rate which is its main purpose and track my fitness with it. Another reason I feel its a bit more accurate is the fact that I can do the same workout days in a row and have never gotten the same amount of calories burned- it might be close but never the same numbers. Your body can vary on alot of things from day to day and your Heart rate can be affected by that (what you eat, acttivities you do, stress, ect.) So when I do the same work out two days in a row and my calories may vary 10-50 more or less I just take it as my body is working harder or I'm starting to get use to the exercise if I'm not burning as many calories. This is purely my opinion on HRM's, I love mine and would recommend it to anyone wanting one(Polar Ft40) I think HRM's with chest straps are more accurate than one's without, for the reason that it detects how fast your heart is pumping and then figures how many calories your body, giving the info you put in it, would burn. If your looking at one without a chest strap I'd just go with what MFP tells ya and save up to get on with a chest strap.

I get 420 calories for an hour of high intensity aerobics on here. I think I'm being cheated!

LMAO....I just saw the same thing....then thought...where's the "wild sex" category? No that that ever happens anymore LOL.

(And that's if it lasts fifteen minutes LOL)
