Proper Heart Rate Usage
HAND GRIPS | THUMB PULSE
Place the palm of you hands directly on the grip pulse handlebars. Both hands must grip the bars for your
heart rate to register. It takes 5 consecutive heartbeats (15-20 seconds) for your heart rate to register
accurately. When gripping the pulse handlebars, do not grip tightly. Holding the grips tightly may elevate
your blood pressure. Keep a loose, cupping hold. You may experience an erratic readout if consistently
holding the grip pulse handlebars. Make sure to clean the pulse sensors to ensure proper contact can be
maintained.
TROUBLESHOOTING-HEART RATE
Check your exercise environment for sources of interference such as fluorescent lights, computers,
underground fencing, home security systems or appliances containing large motors. These items may
cause erratic heart rate readouts.
You may experience an erratic readout under the following conditions:
• Gripping the heart rate handlebars too tight. Try to maintain moderate pressure while holding onto the
heart rate handlebars.
• Constant movement and vibration due to constantly holding the heart rate handlebars while
exercising. If you are receiving erratic heart rate readouts, try to only hold the grips long enough to
monitor your heart rate.
• When you are breathing heavily during a workout.
• When your hands are constricted by wearing a ring.
• When your hands are dry or cold. Try to moisten your palms by rubbing them together to warm them.
• Anyone with heavy arrhythmia.
• Anyone with arteriosclerosis or peripheral circulation disorder.
• Anyone whose skin on the measuring palm is especially thick.
