Short of surgery, you re not going to lose a stomach in 2-3 montyhs (though you could go the distance in toning yourself there in that amount of time). The stomach area is sort of the Fort Knox of fat, only the most strenuous exercise will break that area down. Also, muscle gain is as permanent as muscle loss - short term gain can easily disappear - you really need to work long and hard to build up appreciable muscle.
well to lose your stomach u need cardio and sit ups. To gain muscles yes those are good options too.
cardio is the best way to lose weight
