Note: As with all exercises and fitness regimens, always use your best judgment when you increase your exercise time or intensity. Fat Burning Target Heart Rate Heart Rate BPM (beats per minute) Maximum Heart Rate Target Heart Rate Zone (keep within this range for optimum fat burning) Age Contact Heart Rate Sensors Contact Heart Rate (CHR) sensors send your heart rate signals to the Console. The CHR sensors are the stainless steel parts of the Handlebars. To use, put your hands comfortably around the sensors. Be sure that your hands touch both the top and the bottom of the sensors. Hold firm, but not too tight or loose. Both hands must make contact with the sensors for the Console to detect a pulse. After the Console detects four stable pulse signals, your initial pulse rate will be shown. Once the Console has your initial heart rate, do not move or shift your hands for 10 to 15 seconds. The Console will now validate the heart rate. Many factors influence the ability of the sensors to detect your heart rate signal: • Movement of the upper body muscles (including arms) produces an electrical signal (muscle artifact) that can interfere with pulse detection. Slight hand movement while in contact with the sensors can also produce interference. • Calluses and hand lotion may act as an insulating layer to reduce the signal strength. • Some Electrocardiogram (EKG) signals generated by individuals are not strong enough to be detected by the sensors. CHR detection may be limited to walking or slow jogging due to the extreme muscle artifacts and hand motion generated by a comfortable running style. If your heart rate signal ever seems erratic after validation, wipe off your hands and the sensors and try again. 33
