Not much has changed in cycling since 1987; sure, the equipment has changed, but not cycling itself. The bikes don't ride themselves.I was an avid cyclist 10 years ago, but hadn't been back on my bike in years and years. I decided to get fit and picked up this book at a used dealer.Results:Five pounds / month weight loss, consistently, across the past four months. I can ride century rides, am more confident on busy streets, and have improved my riding position to prevent knee damage.Look, the only way to get fit is to exercise. Think about how much a gym membership costs. Think about how much a Nautilus machine costs. Now consider the cost of this book ($4 for me) and a decent bike ($100 used, $350 new).You're not buying a book, you're buying a life change.
