Calorie expenditure is related to amount of work needed to make muscles move the affected parts of the body, so the farther or faster you move the body, and the more weight you move, the more will be burned.
I burn 910 calories in 1 hour of hard cycling according to my Garmin.
depends what your doing
You can do 1000 jumping jacks or run 3 hours
How long it takes to burn off 3000 calories depends on the activity you choose and your size. If you select a moderate activity that burns off 200 calories an hour, it will take you 15 hours to burn off that many calories.
I5 hundred seconds in a round 300 by 400 pool!
it wouldn't cos u would be dead
A gram of any kind of fat is about 8 calories. The time to burn it depends on your activity. You burn calories even at rest (1.6 calories/hour) so at rest it would take you about 5 hours to burn 1 gram of fat. If instead of sitting alone in a chair you were kissing someone you would burn 8 calories in about 5 minutes. If you were walking you would burn 8 calories in 2 or 3 minutes.
It depends on your weight and the intensity of exercise. For me, it would take over four hours.
Depends on what you are doing and how hard you are exercising. I have a running watch that estimates calorie burn and it typically tells me about 100 calories per mile. So a 15 mile run would do it for you.
That would be impossible. 3500 calories in a pound of fat means you need to burn 35,000 calories in a week. An average person (150lbs, maybe) would burn off 10,500 calories if they ate nothing at all for a week.
30 or 40 minutes.
3 hours
