Has anyone experienced a 'popping' sensation in their lower spine while doing full sit-ups? For some reason, even if I'm on a mat, I get this 'pop' or crack (something like cracking your knuckles) when I do them. It doesn't hurt - but it's uncomfortable and sometimes makes me nervous enough to stop. Sometimes I also get this in my shoulders when doing shoulder exercises (like arm lifts or something) - but it's pretty consistent in my spine with the sit-ups.
Are full sit-ups not good for your back? Is this something that is uncommon and maybe could be a bone/joint problem? Or possibly my surrounding muscles are not strong enough to support the exercise?
