Last year, my partner and I worked with Jennifer on the advice of our chiropractor.  She designed an exercise program for us that addressed ongoing problems that include knee injuries, back pain, and arm injuries - exacerabed by our work as seasonal professional gardeners.  To my great surprise, last Boxing Day I hurt my back but it lasted only a few days as opposed to months like two years before. I credit this to the exercises that I have been doing, thanks to Jennifer, that have strengthened my body.
