Hill
The Hill program simulates going up and down a hill. The resistance
in the pedals will steadily increase and then decrease during the
program.
Plateau
The Plateau program provides a steady state exercise with warm up
and cool down periods.
Interval
The Interval program takes you through high levels of intensity fol-
lowed by periods of low intensity. This program increases your endur-
ance by depleting your oxygen level followed by periods of recovery
to replenish oxygen. Your cardio vascular system gets programmed to
use oxygen more e ciently this way.
