there's a set of about 10 chiropractor exercises, too. i'll look for them on the internet. basically, the first one is to simply lie down on the floor with knees up, soles of the feet down and feel your spine move into a better alignment against the floor. just rest a few minutes. then bring one knee to your chest. hold it. put it down. bring the other knee to chest. hold it . bring it down. and then both knees to chest and down.
even, this one exercise really alleviates lower back pain. sometimes the cause of neck pain is actually that your lower back has become weak and the muscles aren't holding the back in place. i find cycling to help my lower back a lot!
when you walk, if you consciously try to tilt the pelvis (tummy tuck) - you will also help to straighten an otherwise- more and more curving spine. and, if you hold a purse or bag on one side - try to alternate it more frequently. heels are very bad for a woman's back. try to only wear them when you have to - and even then - lower heels (like 2" or less).
if you are ready for more back exercises - after you bring knees to chest and down again. take both feet and stretch them completely over your head. the first time you may not be able to touch your toes to the floor (or you may!). keep doing it every day and soon you will be able to. it really pops everything into place as well. and increases circulation.
you can do standing exercises too. you can stand and lean forward as far as possilbe. stand up. lean to the side as far as possible, and up. and then, other side. also, as prometheus said - the neck to all four sides and then rotate. when i cycle i also like to rotate my arms. i think the general idea is to stay flexible enough that when you are sore it is only a minor thing and not a degenerative state.
