If you are trying to rebuild muscle areas that have gotten weak from sitting long hours, and need to be careful of your spinal stenosis (my personal experience), then this is a great DVD for getting started. The movements are not fancy, but they are targeted to strengthen the hips, outer thighs, side core and arms. Good for elderly or anyone who is just beginning to try to rebuild hip, thigh, and core stability. There is no swinging of the arms and twisting of the torso that is bad for spinal stenosis. It's not floor work, just standing and chair if needed. What I learned in PT is how thoughtfully these simple exercises need to be done. Feel every muscle that is engaged. The final routine is a Tai Chi type flow built from the elements practiced in the earlier 12-18 minute sessions. The DVD is older, so there is no handy menu at the beginning that allows you to pick from the intro and the subsequent routines. You have to plow through the intro each time and use the remote to click forward by chapter to the one you want to do. Still, its hard to find exercise routines that are simple and effective for those who are far from the athletic end of the gym.
