Last month I wrote about sitting too much with suggestions for moving throughout the day and keeping your body aligned properly.  You can make great progress with maintaining proper posture with a simple hard ball.  I gifted Foot Rubz to some of my clients, but any small hard ball works well.  I also like using a rugby ball.  I have a quick test for you to take, so grab a ball (steal one from the dog if you need to) and follow along with my first you tube video.
