How are people burning such high calories

My heart rate monitor *says* I can burn 900 calories doing an hour of Insanity. HOWEVER, I am very out of shape, so sometimes my heart rate gets up much too high when I try to do it high intensity instead of going at a slightly slower pace. Also, I feel like my HRM might be overestimating, if that's possible for an HRM, so I always put in less on Myfitnesspal than I actually did.

I go by the cardio machine I am on, I enter my weight, age, so weight has a factor, plus if I am on treadmill how fast one goes, and or incline. I tend to push myself where I would not be able to talk to others around me. I have my headphones on, but sometimes folks will still want to talk, but I push myself where I am breathing heavy, I aint got time for dat, (talking that is) laugh. I want to get in there get my workout done and leave. I use a treadmill and something called AMT by precore, the AMT it shows 620 calories in 33 minutes, usually for me and sometmies when I am really on my game I can hit 630ish, but I seriously push it hard, I put that on the hardest resistance for 33 minutes and GOOOO.

On the treadmill I can do 3.1 miles in 33 minutes, just recently did 1 mile in 9 minutes 20 seconds, these are not anything really fast, but for a guy at 230 and one the doc labels obese I think that is pretty darn good, though my fastest 3.1 mile run was 28 minutes. But now I can go 30 minutes easy without walking at 5.5 mph, if I push faster I will have 1 or 2 walk points for a minute, then back up to 6.5 or 7 mph,

Hopefully this will help some, but my suggestion is push yourself, each time you go try to go faster, farther, more calories, beat one at least, better beat 2, and when you can beat all 3 you know your on your game and seriously progressing.

irrelevant. who cares?

questions you should be asking yourself are things like "what sort of exercise regimen can I commit to doing regularly?", "how should i structure my diet in a way that will keep me satiated?", "what are my fitness goals?"

Good advice there.

Even with a HRM, you are still only getting estimates of a calorie burn. The estimates are better than some one-size-fits-many calculation from a website, but it's all just estimates. Speaking very generally, burning too much over a calorie per minute is often inflated figures.




^^Yes I like this information, very much!
Also, someone who weighs 250 lbs will burn more calories than someone who weighs 125, doing the same activity for the same length of time.

But ultimately, what Taso posted is better info. A HRM is good for getting calorie burn estimates when calculating target calorie goals and such. But really, for long term fitness goals, consistency, gradual improvement, more strength/flexibility/heart health are way more important than the numbers.

i used to post very very high intensity work outs. i got called out on them. but i started to look at what i did.

warm up:

either 8 minutes on the treadmill (high incline walk, or low incline run) or 8 minutes of jumping rope
50 jumping jacks
20 body weight squats
10 lunges
10 hip thrusts
20 push ups
5 pull ups
20 spider-mans
5 minutes of dynamic stretching

Then after all that, i would start my work out. i'd go for a run with a weighted pack, or a long bike ride, or a swim for cardio.

On lifting days i'd do the same warm up, and my main lift would be a barbell lift like overhead press, dead lift, squat, or chest press. Then i'd do some accesory work. maybe even a crossfit style WOD. High intensity, keep the heart rate up, little to no breaks.

Then i'd cool down by jogging/walking it down, bringing my heart rate down slowly. and i'd finally end my work out with some stretching.

so while maybe my calorie burn might have been high, maybe even a little inaccurate, the main this is that i saw results. a lot of results.

Folks can look at things positively or negatively, personally I know I bust my *kitten* when I go to the Y, I only use the calories as a indicator of how I did vs last time and previous, I also use how far it shows I went on the machine as a indicator, I been going to the Y 3 to 4 days a week since 2009, so those numbers weather real or not dont lie in terms of how well I perform on the machine. So dont worry if 1k calories is real or not, just look at it as if you really go HARD that is your number to beat next time, if your gym does not track numbers, keep track yourself so you know if you are getting better and performing better, they also help you to push yourself to go harder to beat the previous. But that is how I do it.

If you can talk to others you aint pushing hard enough, Push harder or go home, it's not time to chit chat, its time to kick azzz

I burn about 1000 calories in two hours. Depends on the exercise I'm doing. My heart rate is at about 160 to 170. Sometimes when I'm doing HIIT it's 180. So it depends on the exercise and the intensity. Each person varies and it depends how much u weight.

It depends ont the exercise and size of person; I do an hour on the elliptical and burn 1000 calories an hour!

I suspect they are using the inflated numbers given by MFP.

This ^^ and they also include things like cleaning etc which should already be counted in daily activity.

They probably weigh more, or get their heart rate very high, or the common one they are overestimating.

A combination of these things.

At 226lbs I can burn about a thousand calories per hour running at a out a 9:30(ish) pace. That is probably a slight overestimation but not much. I've seen the math on a physiology site and it works out pretty well. Intense swimming is fairly close but probably closer to 750 or so per hour. Keep in mind that body comp factors in as well, muscular builds burn more than fatter people.

Myf is a rough guideline, nothing more. Hrm data is closer, but there's still going to be variance from one person to the next

Dont go on calculators and stuff because those are rubbish, get a hrm that is ecg accurate. Mfp says my weekly goal is 1940cals and i am currently at 4691 and got 1 day left. I do 2 workouts every day, in the morning i do 30 day shred and in the evening Les Mills Combat :glasses:
