As we age it becomes more and more important to eat healthy and exercise.  And when I say exercise that does not mean running marathons, doing bootcamps or taking high intensity aerobic classes.  Those higher-impact exercises just don't feel as good as they once did. In fact, the aging of the baby boomer generation is one reason low-impact fitness choices like elliptical trainers, recumbent bikes, yoga, and Pilates have become so popular.  Low impact exercises are easier on our joints and can be just as effective as the higher intensity exercises we loved in our 20's and 30's. My personal favorite  is bike riding. I do a daily 30 minute bike ride and have seen great results from this.  I also do a weight program that targets all muscles groups ( minus the quads and calves, I get enough of that on the bike) using light weights and only for 20 minutes. This time frame keeps you moving through the exercises which keeps your heart rate up and targets 2 muscle groups in 1 set of exercise...
