need to be able to perform a full situp, whats the best training for this?

[tracyburgess]

hi everyone im applying for the police and failed my first physical, my main issue is performing a full sit up which im really struggling with.
I have had 2 children both born by emergency section and had a back injury a few months ago.
I have read performing full situps isnt good for people who have had a back injury, but if i cant do one i will fail again.
anything else i can try to do this?

Do you only have to do one? Why can't you do one right now? Are you just unable to or is it painful?
