Hi There,

I recently joined my local gym which is located on campus where I work as I work for a University. I've been at the gym now for about a month. I go about 2/3 times a week and work out my back and bi-ceps and chest and tri-ceps. During these work outs I have a situp session.

When doing situps I get to about 10 and then get this back pain. Its pain in my lower back and I've always been told to stop if you get any back pain. Anyone have any ideas whats causing this? I am failry fit chap, 61kg, 5.7ft. I'm doing situps on a mat/swiss ball and I get the same problem. I have tried bigger and smaller swiss balls and still get this pain. Any suggestions would be great.

Danny
