Muscle Activation Figure
There is an anatomical figure located at the top of the console. This figure will light all areas that
are activated when using the bike. These will light up during any of the programs. You can control
which muscles are activated by customizing the resistance profile during the set up phase of console
programming. If you accept the default program profile, the selected program will determine which
muscles will be activated by automatically adjusting the resistance. Generally the following guidelines
hold true:
The upper body LED's will not light
ƒ
The lower body lights will activate in three degrees of engagement: Green represents minimal muscle involvement,
ƒ
yellow represents medium involvement, and red represents full or heavy activation.
These are the different scenarios for lower body muscle activation:
ƒ
Levels 1-10: Green – Hamstrings & Gluteals light up; Amber – Quadriceps & Calves light up
ƒ
Levels 11-20: Amber – Hamstrings & Gluteals light up; Red Quadriceps & Calves light up
ƒ
Heart Rate % Profile
The console LCD screen will display your current heart rate anytime a pulse is detected. The Bar
Graph, located to the right of the LCD screen, will show your current heart rate % in relation to
your projected maximum heart rate, which is determined by your age that you entered during the
programming phase of any of the 10 programs. The significance of the bar graph colors are as follows:
50-60% of maximum is Amber
ƒ
65-80% of maximum is Amber and Green
ƒ
85-90% or more is Amber, Green, and Red
