Determining Your Optimal Heart Rate Zone

There are five basic heart rate target zones. Simply select a zone that
matches your percent of maximum (%) heart rate based on the fitness
goal you want to achieve during a particular exercise.
Zone % Goal
1 50% to 60% Light exercise
2 60% to 70% Weight management
3 70% to 80% Aerobic base building
4 80% to 90% Optimal conditioning
5 90% to 100% Elite athletic training
Before you can set your %, you first need to determine your maximum
heart rate. You can use many methods to estimate your maximum heart
rate.

heart rate, you can set the zones described in the table on the previous
page.
