ORKOUT
This intense, varied workout is designed to help more experienced users break through fitness improvement plateaus. The
workout alternates between two target heart rate goals as quickly as possible. The effect is similar to that of running sprints.
When setting up the workout, the user enters a target heart rate. After a warm-up, the intensity gradually increases until the
user reaches the 100 percent target heart rate goal. Then, that target rate is maintained for a stabilizing period. Afterward, the
intensity decreases. When the heart rate falls to the 75 percent goal, it is maintained for another stabilizing period. The pro-
gram repeats the alternating of intensity levels, continuing this pattern for the duration. See the chart below. The user must
grasp the hand pulse sensors or wear a wireless heart rate chest strap to enable the computer to monitor the heart rate.
EXTREME HEART RATE Workout Profile
30
* Target Heart Rate (THR) is a percentage of the theoretical maximum. For example, a 40-year-old user's THR for the HEART RATE INTERVAL workout is 144. This workout targets
80 percent of the maximum, so the equation would be (220-40)*.80=144. A 20-year-old user’s THR is 160, so the equation would be (220-20)*.80=160.
