Treadmill

XT685

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.

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 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. Your cardiovascular system gets programmed to use oxygen more

efciently.

Incline: This program will spike similar to the speed prole, 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 INCLINE

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.

SPEED INCLINE

FUSION (Speed/Incline prole graphs are the same as the Interval Program above)

Resistance: This program takes you through high levels of cardio & strength 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. Your cardiovascular system gets programmed to use

oxygen more efciently.

Incline: This program will spike similar to the speed prole, 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
