For several years I had lower back pain reoccurring regularly - pulled muscle. I tried the standing desks and it helped but not that much. Then I heard it was due to weak core muscles. Once I started doing the exercises it helped quite a bit. I just did the ones where I was on my back and I did them in bed.

But once I stopped having back pain as often then I stopped doing the exercises. Mainly because the exercises are boring and easy to skip. For the last year I have had luck using the slendertone waist band. It seems to work. I play video games to take my mind off the 30 minutes of discomfort - plus it is positive reinforcement .
