How many crunches do you have to do a day to lose 20 pounds?

Answer 1

Crunches won't make you lose belly fat. Crunches work the abdominal muscles and therefore help develop (grow) the abs. Furthermore there is no thing as spot removal (removing only belly fat) you can remove body fat and eventually fat will come off your belly. To remove fat you must reduce your caloric intake and do cardiovascular exercise

Answer 2

Sorry to say this, I don’t know what to do. As experts said; the recommended weight loss in a week is 2-3 pounds. According to this in one month we have to loss only 8-12 pounds, that too we can lose with healthy diet and exercises. With diet and exercises we can lose 30 pounds in a month but it’ not at all healthy. Only with the help of exercise we may not loss 30 pounds in a month, first of all our body cannot bare that much of stress.

Answer 3

Aerobic activity would be more helpful towards that goal.

Answer 4

Cardio is needed for weight loss. Crunches won't do a thing, but build muscular definition under fat which won't show.

Answer 5

to lose about 70 pounds doing 50 crunches a day, you would have to do that for about 935 days

Answer 6
