I'm currently down 53lbs. It was mostly done through CW, but I've continued losing weight with greater energy and more fulfillment through PB. Unfortunately, 53lbs is just the proverbial "drop in the bucket" for me, but every little bit counts. =) Anyway... I've noticed that I've had increasing lower back pain as my weight has come down which I find odd. My lower back has always been a sensitive spot for me, prone to being thrown-out and tweaked, and I'm looking for some light to medium exercises to target those muscles and start strengthening it up/loosening it out. I'm searching online now, but if anyone has any great exercises that they are partial to I'd appreciate the input!
