Flat or fat

Do your abs need some work?  So do mine.  I  cannot seem to get there though with all the work I have been doing.  I heard that abdominal exercises for a flat stomach are not all that they are cracked up to be and a good overall workout will suffice.  Can I really slim down sooner than later if I try  some of these green tea diet pills my mom keeps buying.  She ended up giving them all to me because she has high blood pressure and they gave her a nose bleed that sent her to the emergency room.  I better be careful too although I do not have high blood pressure.
