Any where between 25-100.
He didn't do situps, silly!
i usually do bout 100 in a row but ive done 300 in a row before i usually do about 500-800 a day
you won't get a 6 pack doing situps try doing crunches, start doing about 10 to 20 then move upto 100 or even 1000 when you feel you can do it. you should see a real difference in about 3 or 4 months.
all five do it
It depends on how fit you are!
Your best bet is to do the situp properly without cheating or trying to get away with sloppy situps. The heavier you are the more calories you should burn with situps but it is very difficult to tell beyond that an exact number.
500 situps burn 100 calories so you need to do more than 2,500

The number of sit-ups a 10-year-old girl should do can vary based on her fitness level and overall health. Generally, starting with 5 to 10 sit-ups per set and gradually increasing as she builds strength is a good approach. It's important to prioritize proper form and avoid overexertion. Always consult with a pediatrician or fitness professional for personalized recommendations.
