It depends on your weight, you degree of fitness, and how much effort you put into it.
An average person jumping rope might burn 11 calories per minute but the higher and faster you jump it can reach the limit to about 20 calories per minute but it depends on your weight and fitness.
Depends on how hard you go at it, and for how long you can keep it up.
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.
there isn't an excersise you can do to burn 2500 calories in a day! if you excersised constantly all day which is impossible almost you would burn saround 1000
I burn 910 calories in 1 hour of hard cycling according to my Garmin.
30 or 40 minutes.
depends what your doing
3 hours
burn 7700 calories on it
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 takes 3500kcal to burn 1 lb of fat, there are 2.2lbs in 1kg so there are 8.8lbs in 4kg. So to burn of 4kg it takes 8.8 x 3500 = 30800 kcal At 1000kcal a day in will take just under 31 days to burn 4kg of body fat.
It depends on what kind of exercise you do, how long you do it, and your height, weight, age, etc.
