INTERVAL
Speed: This program takes you through high levels
of intensity followed by recovery periods of low
intensity. This program utilizes and develops your
“Fast Twitch” muscle bers which are used when
performing tasks that are intense and short in
duration. These deplete your oxygen level and spike
your heart rate, followed by periods of recovery and
heart rate drop to replenish oxygen.
Incline: All of your lower extremity muscles will
be equally challenged throughout this program.
The incline alternates between 25% and 65% of
maximum elevation.
HR 1 / HR 2
The default value is 65% or 80% of your projected
rate maximum. You have the option of changing your
target heart rate. The machine will attempt to keep
you within ve beats of your target heart rate.
