Oh oh oh and one more thing;

Try doing core exercises that strengthen your lower back as well as your abdominal muscles.
I'm not talking getting a six pack here, though; I'm just talking strengthening your core muscles that stabilize you.

One move to use is the Superman, where you simply lay on the floor face down and lift your arms and legs/hips off of the ground. You hold this position for as long as you can, then let your lower back muscles slowly let your arms and legs down to the ground again.
*There is a variation of Superman called Alternating Superman, which is very helpful. Get in the same position as the standard Superman, then alternate lifting up your right arm/left leg with your left arm/right leg. Keep in mind the whole time that you have to still keep everything up off the ground; sagging means trouble!

Another move to use is the Plank, which brings your whole core into play. You get into a push-up sort of position, but instead of your hads being on the ground, it's your elbows. You hold this pose until your back starts to sag. The key to building your core with this pose is to build up in 15 or 30 second intervals until you can hold it for AT LEAST 1 minute.

Try doing these moves, alternating back and forth between them for...ah...maybe 3 sets. Basically:
Set 1-- *Superman -> *Alternating Superman -> *Plank

Do this 3 times each night until it becomes almost easy.

Trust me, you will see an improvement.
