Heart rate target zones are displayed at the top of the heart rate display box and are based on calculations from Full Frontal or Half Monty fitness tests. Zones will only be calculated if a heart rate monitor was connected to the app during the test. Heart rate zones are given as guidance during the workout, but your heart rate may fall outside of the displayed range.
Your current heart rate will be displayed in the middle of the box as a larger number when a heart rate monitor is connected to the app.
