EXTREME HEART RATE
TM
This intense, varied workout is designed to help more experienced users to 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 Polar telemetry heart rate chest strap or grip the Lifepulse
TM
sensors throughout the work-
out.
When setting up the workout, the user enters a target heart rate. After a standard three-minute warm-up, the intensity in-
creases, until the user reaches the target heart rate goal of 85% of the theoretical maximum (HRmax). That target rate is
maintained for a stabilizing period. Then, the intensity decreases. When the heart rate falls to the 65% of HRmax goal, it
is maintained there for a stabilizing period. The program repeats the alternating intensity levels, continuing this pattern
throughout the duration. The program does not proceed to a new heart rate goal until the user reaches the current goal.
