im 15 and i do 200 a night, but you need to make sure you are doin them right or else you can end up dameging your lower back.
if you are looking to tone up your abs then you should also try not to have alot of stomach fat because that will cover up your rock hard six pack.
25 sit-ups every hour for 5 hours a day for 5 weeks. Worked for me. Staying in good shape and eating protein helps too.
50 sit ups in mine seems pretty goxh darn good
an average teen should be able to do 20 sit ups without stopping and around 200 a day.
as much as you can and eat healthy.
30
