During Your Workout
CHAPTER FOUR: WORKOUT SETUP
During your workout, press to go back to Workout Setup
as often as you like to change settings or even set up an entirely
different workout. While in Workout Setup, pedal resistance is
reduced.
If you change programs during your workout, Workout Setup
assumes you want to enter the new program at the same place you
left the old one. The exceptions to this are Heart Rate Control,
Custom Programs, and Fitness Test programs.
