Sit ups and squat thrusts work for me.

Also finding something to do pull ups on is good.

... This would probably be better in the Sports section but I'm a personal trainer so I'll help... Sorry for it being REALLY in depth! ( I have alot of time right now... ) Excuse any bold, italics mistakes... I typed alot and maybe missed a / or something

Basically you need to get rid of body fat. Aerobic exercises will burn the fat better and you need a proper diet ( low salt, low sugar, high protein ). Here are some exercises. Start at easy, expert is highly intense and you will more than likely hurt yourself, but I'll leave it in for later work outs down the road.

For your upper abs.
Easy - Basic Crunch
Start Position
Lie on your back with your knees bent and your feet resting flat on the floor. Your neck and head should be relaxed with your hands at the sides of your head.
The Movement
Using your upper abs, curl your upper torso so your shoulder blades lift off the floor. As you curl up using your abs, your sternum (chest bone) should be aimed toward your bellybutton. At the top, contract the abs intensely and then slowly lower your torso, lightly touching your shoulder blades to the floor. Repeat.
Harder - Bench Crunch
Start Position
Simply lie on the floor with your feet positioned atop a bench (or chair). Your knees should be bent at a 90-degree angle. Place your hands gently on the sides of your head and take a deep breath.
The Movement
Then, concentrate on flexing the upper abdominal muscles, pushing your lower back into the floor, and slowly curl your shoulders toward your knees as you breathe out. Aim your elbows toward your knees, flexing the ab muscles more with each inch your elbows move upward and inward.
When your shoulders and upper back have curled up off the floor and your elbows are six to eight inches from your knees, hold that position for a count of "one-thousand-one, one-thousand-two" and flex those abs while pushing down with your lower back! Then, slowly return to the starting position while you breathe in. Pause for a moment, and then repeat.
Expert - Cable Crunch
Start Position
Using the high cable pulley, attach a rope handle. I prefer the rope because it allows the most natural grip and freedom of movement. If a rope is not available, a small V-grip handle can be used as well. Start with a light weight.
The cable crunch is just like the ab crunch—flipped over. Instead of lying on your back, you are on your knees, facing down. From the kneeling position, your upper legs are at a 90-degree angle to the floor, and your torso is almost parallel to the floor, which your back slightly arched. Hold the ends of the rope in each hand with your hands above your head.
The Movement
Keeping your pelvis and lower back stationary, begin to pull the rope down toward the floor, in toward your knees. Stop before you reach the floor or your knees and flex at the peak contraction point for a full two seconds. Then slowly allow the weight to "uncurl" your body, pulling your back to the staring position. Allow the weight to pull you beyond horizontal, slightly arching the back and stretching the abs. Stop. Contract again. These will feel different than floor crunches because the resistance from the cable is constant. With floor crunches, the resistance (due to the angle of the body and the pull of gravity) reduces as your body rises.
For your lower abs.
Easy - Reverse Crunch
Start Position
Lie on your back with your knees bent and your feet together six inches above the floor. Place your hands behind your head, like you would if you were getting ready to do an ab crunch.
The Movement
Keeping your feet close to your hips, contract your lower abs, slowly bringing your knees toward your chest and lifting your butt off the floor. Once you have curled your lower body as far as you can, slowly lower to the starting position. Repeat.
Harder - Hanging Leg Lift
Start Position
To begin, hang from a pull-up bar with a shoulder-width grip, or utilize arm straps that allow you to hold your bodyweight with your upper arms, instead of just the grip of your hands. Next, allow your legs to hang down, keeping them very relaxed, so your knees are bent a bit and your toes are slightly pointed.
The Movement
From here, take a deep breath, and begin to lift your legs upward, while you focus on contracting your abs. Breathe out slowly, continue lifting your legs while you roll your hips upward. Continue until your feet are pointed straight out and hold that contracted position for a full count of "one-thousand-one, one-thousand-two." Then, slowly lower your legs to the starting position, take a deep breath, and repeat.
Expert - Swiss Ball Leg Lift
Start Position
Position a Swiss ball in front of something sturdy you can hold onto, like a power rack, a Smith Machine, or a very heavy-duty exercise bench. Position the Swiss ball a couple of feet in front of whatever you're going to hold onto, then sit down on the Swiss ball, take a step forward with your right foot, a step forward with your left foot and lie back. Then, extend your arms behind your head and grasp whatever you're going to use to anchor your body. Make sure your hips and shoulders are positioned on the Swiss ball, and that you're not too far back or too far forward. Bend your knees a bit and slightly point your toes.
The Movement
Take a deep breath and begin contracting your lower abs, lifting your legs, and curling your hips up toward your shoulders. Be sure to keep your neck in a relaxed position with your vision focused upward toward the ceiling. Continue to slowly raise your legs until your toes are pointed straight up, with your legs at a 90-degree angle. Then, very slowly, lower your legs to the starting position. The slower you lower your legs on this exercise, the better.
Once you've reached the starting position, take a deep breath, get your balance, and lift your legs again.
For your Obliques
Easy - Side Crunch
Start Position
Lay on your back with your knees bent, as if you were setting up for a traditional crunch. Put your feet on the ground, your left hand at the side of your head, and your right on the left side of your midsection. Keeping your knees together as one unit, let them both fall to the right. Make sure you keep your head and chest facing the ceiling.
The Movement
Crunch your chest toward the hip that is facing up. Even though your lower trunk is twisted to one side, crunch your upper torso straight up. When you have completed one set, change your body position to exactly opposite, and do an equal number of repetitions with your knees and lower torso turned to the other side.
Harder - Swiss Ball Side Crunch
Start Position
Sit on the ball, walk your feet forward, and slowly lean back until you are comfortably lying back on the ball. With your feet shoulder width apart, put your right hand at the right side of your head and put your left hand on your right obliques. Slowly roll your body toward your left until the outside of your left foot and the inside of your right foot are touching the ground. Try to spread your legs so your feet are slightly more than shoulder width apart.
The Movement
Crunch your chest toward the hip that is facing up. Even though your hips are twisted to one side, crunch your upper torso straight up. When you have completed one set, do an equal number of repetitions with your lower torso turned to the other side.
Expert - Twisting Cable Crunch
A variation of the cable crunch to work Upper and Oblique abs is to grip the rope in one hand and perform a twisting crunch. Be sure to use less weight when you try this exercise. Twist away from the hand holding the cable. Follow the directions above for the cable crunch but twist 3/4 the way into the crunch.

They aren't completely unhealthy if you still have the proper ammount of body fat percentage.
