So I've been doing this for about 4 weeks. In some stretches I'm seeing actual improvements, some others, not so much. I like that it doesn't negatively impact my joints. We have a DVD of a good 20 minute stretch routine. I can see us doing this even when we hit the road. Now I wish I had done this sooner in life. Many of the stretches are similar to what I did in football & wrestling practice over the years.
