back problem?

[aasads]

I have been working out lately and when ever i try to do sit ups just above my butt it works real bad. I think its my tail bone but im not sure.Anyone know what the problem is?

I get the same back aches. Sometimes it lasts for days, then goes aways for months. I suspect it is from having a pot belly and weak core muscles.

I'm not sure what the problem is, but i recommend trying doing sit ups on a softer surface and see if the pain persists. You could have a bone bruise as well from getting hit there.Check with your doctor.
