If you do not already own an ANT+ compatible heart rate monitor, you may purchase the Peloton heart rate monitor.
If you are not using a Peloton Heart Rate Monitor, you can check if your heart monitor is ANT+ here. Once you are on the site, choose the "Heart Rate Monitor" filter under the 'Categories' section on the left side of the page.
If your heart rate monitor is ANT+ compatible, the metric for your heart rate will automatically appear in the top left of your touchscreen. Please note, your Heart Rate Monitor must be on prior to starting the class. To make sure your Heart Rate Monitor is on, ensure the sensors are lightly wet (with water or sweat) before placing the leads on your chest.
