How do people burn 1k cals?

The better shape you are in the harder it is to burn calories. Your calories burned is based on how high your heart rate gets. The higher the HR the high the calorie burn will be. The more you workout the better your endurance will get. There are supplements you can take before a work out that will help you increase your energy level for workouts. My trainer has had me try some. I wouldn't fret too much. What a lot of people don't understand is there are different workout zones. The lowest zone is the fat burning zone and you will burn less calories in this zone but a higher % of them will be fat calories. The higher your heart rate gets the more calories but the number of fat calories decreases. For example, someone who burns 1000 calories may have only burned 20 fat calories while someone who burned 200 calories burned 100 fat. It just depends on what you are looking to do. You are supposed to train in all 3 zones throughout the week.

Burning more than 400-500 cals in a single exercise session is largely BS if done by anyone that hasn't had endurance training or supplemented energy.

Even the most hardcore athletes drink gatorade and such for the sugar and calories.

Everyone else can say what they want... but go beyond the 4/500 mark and you'll probably 'bonk'... runners term for when your body runs out of a ready supply of energy.

That being said, as you get in better shape you'll be able to run faster and farther every time! It will ALWAYS take more than an hour's work to burn 1k.

For example, I usually get through about 1200 during a rugby practice. BUT of a two hour practice, I log 90, because I KNOW I ain't running my butt off for the full two hours.

I have a hard time believing anyone actually burns 1k calories in an hour doing anything. I'm not calling anyone a liar, just saying I find it hard to believe.

I don't know what type of cardio you are doing, but if you can't complete an hour perhaps you should try interval training instead of straight hard core cardio. I can easily do an 1.5 hours of Zumba (well, kinda easily) and once completed a 2 hr Zumbathon (THAT was hard). But I couldn't run for 1hr straight unless I was being chased.

Like me, you are a shorter female. We burn less calories than other people. Its because it requires less for us to get going. It unfortunately means we don't get to eat as much as a 6'11" male. To me, its all good. On me (and i bet you) 4 pounds is literally the difference between pant sizes....Taller people, it could be anywhere from 10-15 pounds. Its all relative!

Btw, I have done Insanity and P90x. In the last couple months, as you can see I only lost 12-13 pounds, but I went down 2-3 pant sizes....I actually can't even tell you what size I am anymore because I can't wear anything size 0 without a belt. I am not bragging, just trying to prove a point.

And a note about HIITs, you never do HIITs more than two days in a row as you must allow time for your body to heal. So, it's not every day that we get a huge calorie burn, but with both types of intense cardio workouts, you rarely will get a really low calorie burn unless you just didn't exert yourself. And, as one poster mentioned, the more your endurance and stamina increases, the lower your resting heart rate will be. It does become more difficult to reach those higher levels, which is why the schedules for Insanity and Turbo Fire progressively get harder and eventually develop into advanced workouts.

On days when I burn over 1000 calories, it is usually from a couple-hour bike ride at more than 16 mph, or some combination of activities, such as today, I will be doing a 45- minute spin class where I will burn about 500-something calories, then tonight I have a 2 1/2 hour dance class and rehearsal where I will burn around 600.

Sometimes I have burned over 800 in an hour spin class, but I don't think I have every burned 1000 calories in just 60 minutes; I'm not sure what people are doing to burn that; perhaps it's not accurate.

blessings.

I just recently got to 980 calories! that was my max and it was because i went to a weight lifting class, and then right after that i went to kick boxing class..

I guess I'd have to run for 1 hour and 45 mnutes or so to do that.

I use the action motion trainer sometime at the gym, and it says I burn 800-900 calories in 65 minutes. One time, when I worked super hard, it said 1000 calories in 65 minutes. I never feel like I'm working super hard on it though. I write the number down but I don't know how much I believe it...I've switched to walking on the treadmill and biking and I feel like I'm getting a better workout.

I'm a distance runner, and at my weight if I go for a 15 mile (approx 2h) run it burns around 1000calories. My workouts will usually total 1-2h of running, and on some days it will include speed work. Then I'll often do strength training, walk around downtown for errands, and do activities throughout the week such as yoga, biking and hiking for fun.

Most people, however, overestimate how much they burn. MFP usually overestimates the calories burned for my runs by around 100 cal. A lot of people also go by the calorie readings on gym machines, which can be as much as three and a half times more that the actual burn if you forget to enter your weight (I have an elliptical that tells me I burn 1400 calories/ hour when by measuring heart rate it was only 400).

It's definitly possible to be burning 1000 cals a day, but I suspect most people just overestimate.
