Agreed - no spot reduction. only total reduction. As far as exercises go, there are a ton of things you can do for your midsection. Here's a few:

1) Crunches - like a situp, you lie on your back with legs bent. If you have a weak neck, you can put your hands behind your head for support - but do NOT pull up on your neck. Then lift your shoulders off the floor up about 6" and then back down. This will allow contraction of the upper/middle ab section without strain to the back.

2) Modified crunches - With crunches, the more weight you have on the upper body, the harder they'll be to do. To make crunches easier, you can extend your arms (like superman or a diver). When you do your crunch, extend arms to a spot between your legs or on the outside of your legs. This will be easier as there's less weight on your upper torso and you'll gain neck strength after a short while.

3) Leg lifts - Lie on your back. Place both hands palms down under the small of your back (lower back). It'll feel like you're almost sitting on your hands. Then lift your head up enough to see your feet. Then, with feet together, raise your legs up 6" and then back down - almost touching the floor. This up/down motion works the lower abs and the hip flexor muscles.

4) Twisting crunches - Similar to a crunch but more advanced. Once you gain muscle strength you should be able to do these. Hands behind your head and legs straight out. You will alternate your right elbow with your left knee and visa versa. This does take a little coordination but its GREAT for the tum tum.

5) Side bends w/weights - Grab a 10lb dumbell. Now stand in front of a mirror so you can see yourself. With arms to your sides and legs together, take the arm with the dumbell and stretch slowly to the outside of your leg (down to the mid thigh). You're just bending over sideways with weight. This works the ouside ab area. Just alternate sides. Remember... the more weight you use, the bigger your abs will get due to resistance. So unless you want a bluky gut, don't go too heavy on weights.

People tend to stress too much on abs and not enough on lower back. They actually work hand in hand. If your stomach gets too weak, your back takes up the slack (to some degree). That's why you get BACK ACHES when you're a lazy slob. (hehe)

I suggest doing roman chair situps. Well, actually its a reverse situp but I think you get the picture. Have your local gym rat or personal trainer show you how to use this correctly. This exercise alone will make your back feel great.

Hope this helps!
