Strength
Resistance: This program has a gradual progression of speed up to 100% of maximum effort that is
sustained for 25% of workout duration. This will help build strength and muscular endurance in the
lower body and gluts. A brief cool down follows.
Incline: There is a quick climb to a moderate, sustained elevation that lasts the majority of the workout
length.
SPEED
Interval
Resistance: 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 fibers 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. Your cardiovascular
system gets programmed to use oxygen more efficiently.
Incline: This program will spike similar to the speed profile, but in different segments (columns); this
means that all of your lower extremity muscles will be equally challenged throughout this program. The
incline alternates between 25 & 65 % of maximum elevation
SPEED
Calories
Resistance: This program follows a quick progression up to the maximum speed level (default or
user input level) that is sustained for 2/3 of the workout. This program will challenge your ability to
sustain your energy output for an extended period of time.
Incline: The treadmill elevation is a quick and sustained progression up to the maximum value (default or
user input) for 90% of the workout duration.

recovery periods of low intensity. This program utilizes and develops your "Fast Twitch" muscle
