Which tool is NOT typically used to encourage physical activity in cardiac rehab participants?

The heart rate monitor is primarily utilized to monitor and assess the intensity of a participant's exercise during cardiac rehabilitation. While it plays a crucial role in ensuring that participants remain within a safe and effective heart rate zone, it does not inherently motivate or encourage physical activity in the same way that the other tools do.

In contrast, tools like the Activity Pyramid visually represent various activities and encourage participants to engage in a variety of physical activities while promoting a balanced lifestyle. Pedometers track steps taken, providing immediate feedback that can motivate individuals to increase their daily activity levels. Accelerometers measure movement and can provide valuable feedback for participants aiming to track their overall physical activity throughout the day.

By focusing on the different purposes each tool serves, it becomes clear that the heart rate monitor is more aligned with monitoring safety and effectiveness rather than directly encouraging physical activity.
