Hill Program - Life Fitness 8500 Manual

19
The Life Fitness 8500 treadmill's patented Hill program offers the ideal configuration
for interval training: periods of intense aerobic activity separated by regular intervals
of lower-intensity exercise. The computerized interval training program has
been scientifically demonstrated to yield greater cardiorespiratory improvement than
steady-pace training.
Not only does the Hill program offer the challenge of alternating periods of high and
low intensity, but the levels of intensity become progressively more difficult during the
course of the program.
The longer the Hill program you choose, the longer the amount of time spent on top
of a hill and at the bottom of a valley. As a result, you may find two 12-minute programs
easier than the 24-minute program because the hill climbing portion is shorter.
The Hill diagram below shows the effort level and recovery periods encountered dur-
ing a Hill workout. Effort and recovery periods are simulated on the display console
by columns of lights in the Program Profile window. The columns move from right to
left during the workout. The higher the column, the higher the incline; consequently,
you must increase your effort.
