XTREME EART
This intense, varied workout is designed to help more experienced users break through fitness improvement plateaus. The
workout alternates between two target heart rates* as quickly as possible. The effect is similar to that of running sprints. The
user must wear a chest strap or grip the Lifepulse
When setting up the workout, the user enters a target heart rate. After a standard three-minute warm-up, the intensity
increases, until the user reaches the target heart rate goal of 85 percent of the theoretical maximum
get rate is maintained for a stabilizing period. Then, the intensity decreases. When the heart rate falls to the 65 percent
of HRmax goal, it is maintained there for a stabilizing period. The program repeats the alternating of intensity levels, con-
tinuing this pattern throughout the duration. The program does not proceed to a new heart rate goal until the user reach-
es the current goal.
† Defined by the American College of Sports Medicine's "Guidelines for Exercise Testing and Prescription" as equal to 220 minus an individual's age.
* Target Heart Rate (THR) is a percentage of the theoretical maximum (HRmax). For example, a 40-year-old user's recommended THR for the
EXTREME HEART RATE TM WORKOUT is 153. The workout program targets a standard 85 percent of the maximum, so the equation would be (220-
40)*.85 = 153.
