how can get flat tummy without losing weight actually my cousin is facing this problem and she is underweight 
need help 
Sit ups, crunches, back crunches. If she does 20-30 everyday her tummy should go in, in 2 weeks and tell her not to eat 2 hours before going to bed. I’m pretty sure she won’t loose more then a pound or 2 with this.
Re: need help
thanks alot
