This review is from: Total Heart Rate Training: Customize and Maximize Your Workout Using a Heart Rate Monitor (Kindle Edition)
Very interesting and informative book let down by the quality of renering to kindle compatible version. Most of the figures are illegible (faint with lots of grey text) and it's impossible to enlarge! This makes large chunks of the text incomprehensible. Buy a hardcopy if you want this book!
