Mio Heart Rate Watch

This fitness marvel gauges your ECG heart rate without a chest strap and uses your personal data (gender, birth date, weight and resting heart rate) to calculate the percent of your maximum heart rate during a workout and time how quickly your heart rate returns to its resting rate after exercising - the best indicator of fitness. It records the calories you burn during a session, and keeps a running tally of the calories you eat during the day. $130. www.gophysical.com
