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.
I burn 910 calories in 1 hour of hard cycling according to my Garmin.
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
burn 7700 calories on it
3 hours
30 or 40 minutes.
depends what your doing
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
In every case to lose weight, we need to burn more calories actually what we had consumed. If you want to lose 3kg in a month, you need to burn more than 1000calories. Any ways 1000 calories is not at all healthy to consume, by taking 1000 calories you can lose weight very fast in earlier days. But the weight all you are reducing from your muscle and water levels in your body. By consuming 1500-1700 calories also you can lose 3 kgs in a month. Try to add some more calories to your daily meals.
It depends on what kind of exercise you do, how long you do it, and your height, weight, age, etc.
