I noticed the same thing. Without physical exercise, my posture gets worse, I have random back pain, and realized I am more prone to injury when I do go and do something active. Currently I exercise every morning for about an hour. 45 min of lifting weights, followed by running 1 mile, and stretching. I have more energy at work, I'm in a better mood, and It motivates me to be conscious of what I eat throughout the day if I start the day off right. The biggest impact on my posture and back pain has been doing the yoga-like stretches every morning. I highly recommend it. Also most office chairs will really mess you up. I've resorted to sitting on a yoga ball or standing. For me, the yoga ball is actually the most comfortable desk chair I have used.
