How can I do sit ups without killing my back? I've been doing a lot of sit ups these past few weeks and It's been killing my lower back. Definitely not muscle pain, it's like my bones are hurting. I've also tried a mat, but that didn't help, I even tried doing them on my bed but that was a whole different set of problems.
I'm only 20, so not old.
You lower back shouldn't hurt. Are you doing the movement correctly? I've seen a lot of people using their psoas muscles to power their sit-ups, and that can really hurt your lower back. You should be doing thoracic spine flexions only.

I started out doing them fast as fuck because that's what I learned in school gym class. After a while I realized I was just using momentum and not actually using my muscles. For the past week or so I've been doing really slow ones, but the pain persists.
There are other ab exercises you can do if this is hurting your back.

Try taking a break from doing them and see if it goes away. If you were fat you may have a bulging disk. In that case, you should go to the doctor.
