How Do I Use This Thing?
(aka: Getting Started with Your Heart Rate Monitor)
The first thing you need to do when you put your heart-rate monitor on is to figure out your maximum heart rate (the old "220 minus your age" formula won't tell you anything). Find easy tests to get your true max in books including The Heart-Rate Monitor Guidebook to Heart Zone Training by Sally Edwards or Total Heart Rate Training by Joe Friel). Or, get heart-rate tests right in the box when you buy one of the new Timex Fitness Series watches (in Target, Dick's Sporting Goods, and REI stores in feminine sizes and at totally affordable prices).
