I find that general light exercise helps. Also changing to a split keyboard has really helped my posture (moving the two halves of the keyboard apart stops me hunching over the keyboard). Also look at what you're doing with you legs. If you're crossing them then you'll be affecting the position of you hips, which in turn affects your back.
