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.
I burn 910 calories in 1 hour of hard cycling according to my Garmin.
30 or 40 minutes.
burn 7700 calories on it
3 hours
depends what your doing
well there are 3000 calories in a pound so times that by 79 3000x79=237000 so about two hundred thirty-seven thousand calories.
3500 calories equal a pound, so if you burn 200 calories a day it will take approximately 18 days to lose a pound, assuming you're burning 200 more calories than you take in.
Are you doing the 12wbt? haha
It depends on what kind of exercise you do, how long you do it, and your height, weight, age, etc.
