Query: Great for lower back pain

I broke a disk in my back 1/09 (L5S1) and then re-injured what was left from a bad cough. This has been the only Pilates DVD that has really given me pain relief. I've tried Crunch Fitness pilates, 10 minute pilates and they were either extremely slow, boring or did not remind me to keep my lower back in the right spot. Purchased as a twin pack at Target.....well worth it.
