If you 60 situps a day will you lose baby fat?

You will definitely build up your core (abs) but it may not be necessarily visible. My abs are more visible than my friend's who has a lot of baby fat yet he can do more sit ups than me. So basically it really depends on the person although running is a much more effective way of losing fat. I recommend you do about 20-40 sit ups and push ups a day, and run 2-3 times a week.
