When I do sit-ups my back lets out a soft "cracking"
noise every time I come back down to the ground. There is
only one crack per sit-up, but it will happen every sit-
up. If I do crunches and keep my back two or so inches
off the ground there is no noise.
I have been doing morning and evening sit-ups
BIG mistake? Well, if you apply the present science to your
situation, yes.
Without recovery, the science tells us, we just break down
the tissues, we do damage. So, the harder one works, the
worse the body becomes. It takes at least 48 hours for a
muscle to recover from stress. If we do not push our limits
a bit, the improvement stops. The body responds to the
stress by rebuilding the muscle DURING RECOVERY. Do you have
only 12 hours of recovery between sessions? DOMS takes about
24 hours to appear, rebuilding at least 48 hours.
So, why not do abcurls/crunches, two or three sets to your
limit, two or three times a week? If you do not increase the
load and the set rep counts get larger than 20, you might as
well just do them once a week as maintenance. To get
stronger, you need to add to the load and you need longer
recovery times.
You want to strenthen the muscles (and other tissues) of
your core. So, you have a training regimen of twice a day
crunches and situps. Do you strenthen other muscles with the
same schedule? Do bench presses twice a day?
Your situp regimen tightens the hip flexors, which can put
additional pressure on the lower back if not balanced with
extensions and hip stretches.
Situps put a lot of stress on the spine. It, too, takes a
while to recover from stress, as bone is a living,
regenerating tissue. So one could even imagine a degradation
in the spine without adequate recovery.

have back problems and as far as I know back problems do
not run in my family. I run twice a week for three miles
with no back problems (shin splits are different
story...).
Anyone know if this is normal for sit-ups? Any help would
be appreciated.

Ever crack your knuckles? (I don't, grosses me out). Did
you ever worry about it? Cracking a joint is from sudden
releases of gas bubbles in the joint, tendons and
ligaments popping back into place, or, in an arthritic
joint, rough surfaces rubbing together. Your back has a
lot of joints in it. If it doesn't hurt, you don't have
arthritic joints, and so you don't need to worry about it.
As far as the utility of a full situp, I thought crunches
were more effective at working the abdominal muscles, as
the strong hip flexors are very involved in a full situp.
