Hi,

I have looked up the mcKenzie method, and have been constantly doing the mcKenzie stretches every few hours (sometimes every hour). Sometimes they seem to help and sometimes not, so it is hard to say if there is an improvement in my condition or not.
Do you have any suggestions to what else I could do? In my job, I sit all day (sometimes for 10-12 hours, including bus rides). I try to sit in a good posture (as suggested in mcKenzie's book), but it is hard, and sometimes painful (though it's hard to say if the pain is the "regular" back pain, or pain from muscles working-out as well). I try to get up and move every 20-30 minutes and backbend.
Will you recommend back (& abdomen) muscle strengthening exercises?
In your experience, how long does it usually last before I could feel improvement?


thanks again!
