I think that especially for us over the age of 50, we need to be good to our bodies and gradually work up on our exercise programs. Don't push yourself too hard too fast. But it is amazing how quickly your body will respond and build strength. Soon, you'll find that the exercise from bicycle riding is really addictive. There's something that happens in our chemistry that makes us need to keep up the exercise. So keep your body happy and give it the exercise it craves.

Oh yeah, I love hills too. But mainly the ones that go down...
