How many sit-ups should I do?

Question

I need to loose weight on my sides and stomach. Is doing a certain amout of sit-up each day going to make a differece or do I need to combine this with another activity?

Answer 1

cardio (running swimming ect)
and side situps (lift one leg in the air and do sit ups to that side.)
that should do it.

Answer 2

stop doing sit ups - all they do is build muscle - they do not burn fat and will make your belly look even bigger.
we cant spot reduce body fat so it just has to be overall fat loss
find daily calorie intake calculator on the net, enter all your stats and it will tell you how many calories you need a day to maintain, take off 300-400cal off that number and thats how much you need to lose.
eat 5-6 small meals a day (eat every 2-3 hours - it optimizes your metabolism)
5-8 servings of fruit and veggies a day
8 glasses of water
have complex carbs for breakfast - they give you energy
have protein (lean meat, legumes etc) for dinner - repairs muscle
cardio exercise (running, jogging, swimming, spinning, elliptical etc) 4-6 times a week for 30-50min (ideally 45min because the first 20-30min body burns carbs and only then starts burning fat), light weight training (more muscle=faster metabolism)
dont consume foods that are made of white flour (white bread, cakes, pasta etc.), sugar loaded foods (cookies, icecream, candy etc) and nothing fried, oily.
ofcourse you can spoil yourself once in a while with a little treat:)
