Query: Good introduction to bicycling for fitness

Let's assume you can ride a bike, but your knowledge stops there. If you are in this situation and are comtempleting riding a bike in order to increase your fitness level, then this is the book for you. This book is a comprehensive look at basic and intermediate level bike riding. Equipment, safety, nutrition and a comprehensive set of training schedules are included in this book. The message in the text is reinforced by the use of humerous illustrations. The only complaint I had about the book it that the beginning rides are 10 miles long, which felt like they were going to kill me! But!, as the author promised, those days rapidly fell behind me and I have quickly increased my fitness level, lost some weight and had fun, all because of this book. Buy it if you are thinking about riding a bike for you health!!
