Exercise Instruction
8
A good exercise program consists of a warm-up, aerobic exercise, and a cool down.
Do the entire program at least two to three times a week, resting for a day between
workouts. After several months you can increase your workouts to four or five times
per week.
AEROBIC EXERCISE is any sustained activity that sends oxygen to your muscles via
your heart and lungs. Aerobic exercise improves the fitness of your lungs and heart.
Aerobic fitness is promoted by any activity that uses your large muscles e.g. legs,
arms and buttocks. Your heart beats quickly and you breathe deeply. An aerobic
exercise should be part of your entire exercise routine.
The WARM-UP is an important part of any workout. It should begin every session to
prepare your body for more strenuous exercise by heating up and stretching your
muscles, increasing your circulation and pulse rate, and delivering more oxygen to
your muscles.
COOL DOWN at the end of your workout, repeat these exercises to reduce soreness
in tired muscles.

PROGRAM 4 (FAT BURN):
PROGRAM 1 (MANUAL):
Computer Instruction
Preset Programs 2-7: Programs 2 through 7 are automatic programs, however the user
may still increase or decrease the tension level of these programs using the “▲/▼” buttons.
Preset program profiles are displayed on the face of the computer. Under these Preset
Programs users may still set a value for TIME, COUNT, CALORIE and DISTANCE. To set a
value, refer to the FUNCTIONS section of the computer instructions.
Computer Instruction
13
D. PROGRAM PROFILE:
The computer contains 12 different programs. You can preset the program time so that the
computer will divide the time into 10 intervals. If the program time is not preset, the
computer will count up 1 minute for each interval of Program 1 (Manual Program), for
Programs 2-12 the computer will use a preset value of 30 minutes, programs will run in
cycle.
Manual Program 1: Program 1 is a manual program; in this
program the user has full manual control of the workload.
Increase the load using “▲” button, decrease the load using
“▼” button.
Target Heart Rate Program 8: This program requires the
user to wear a Heart Rate Transmitter around their chest.
This program is controlled by heart rate. When the user
selects Program 8 the PULSE window located on the
monitor will display a flashing 90 (the initial setting value), at
this time the user may input their desired Target H.R. from
90-220BPM. In this program the computer will automatically adjust the tension level during
exercise according to the users' heart rate, detected by the heart rate transmitter, in order to
keep the users heart rate within the zone of plus & minus 5 BPM of their set Target H.R.
PROGRAM 9 (user setting):
User Setting Programs 9-12: (U1-U4) Programs 9 through
12 are programs that allow the user(s) to manually preset
each of the 10 intervals in order to create personal exercise
profile(s). To create a profile scroll through the User
Settings Program until “Column” flashes on the Monitor,
press the “ ▲ / ▼ ” buttons to create your exercise program,
press the ENTER button to confirm the first Column of your exercise profile. Repeat this
process to create additional Columns.

Under the User Settings Programs 9-12 (U1-U4), users may still set a value for TIME,
COUNT, DISTANCE and CALORIE, (in that order), to set press the ENTER button to select
the program, use the “ ▲ / ▼ ” buttons to set the function values, press the ENTER button
to input the values. Or pass some of the inputs, by pressing the ENTER button. The values
will be stored in the memory after setup. Users may also manually increase or decrease the
functions value in each interval by pressing the “ ▲ / ▼ ” buttons, the value stored in the
memory will not be changed or affected by doing this.
NOTE:
1. Your personal exercise profile will be stored in the memory of the monitor.
2. When you reach one of the targets such as TIME, COUNT, DISTANCE or CALORIES,
the monitor will produce a beep sound and then stop.
3. If you set more than one target and would like to continue, press START to begin the
exercise again.
4. The maximum number of users able to create a personal exercise profile is 4.

TRAVEL DISTANCE INDICATOR
Indicates the distance traveled on the rower during
during exercise.
E. PULSE RECOVERY FUNCTION:
NOTE: To use this program, you must wear the Heart Rate Transmitter.
The Pulse Recovery function is used upon completion of an exercise, the function
measures the amount of time it takes for the users' heart rate to return to a resting heart
rate, the quicker the users heart rate returns to a resting heart rate the better. The computer
monitors your heart rate for 60 seconds and then calculates a Pulse Recovery value from
F1- F6.
F1.0 = Excellent F2.0 = Good F3.0 = Fair
F4.0 = Below Average F5.0 = Not Good F6.0 = Poor
The readings mentioned are to be used as points of reference, this information is NOT to be
used for any medical reference or purposes.
When starting the Pulse Recovery function, a “ ” symbol will be displayed, after 5 seconds
your heart rate will then be displayed. Once your heart displays on the monitor, press the
Pulse Recovery button, during the Pulse Recovery function, only the PULSE and TIME are
active. The TIME will begin count down from 0:60 seconds, during this time the “ ” symbol
will blink, when the TIME reaches 0:00 the computer will sound an audible alarm for ten
seconds and then display your Pulse Recovery reading from F1.0 to F6.0. (During Pulse
Recovery, press any button to stop audible alarm. Press any button to exit Pulse Recovery
function).

F. HEART RATE MONITORING:
To achieve the maximum results from your workout on the ASUNA 4500 Rowing Machine
it is imperative that you exercise within your target heart rate zone for a minimum of 20
minutes. Studies have shown that exercising below your target heart rate zone will not allow
you to burn fat or improve cardiovascular fitness, working above your target heart rate zone
is counter-productive as well.
Everyone has their own specific target heart rate zone, when exercising your main goals
should be reaching that zone and staying within that zone. Determining your personal target
heart rate zone is calculated by the following:
STEP 1: Find your maximum heart rate using this formula:
220 - Your Age = predicted max heart rate.
Example: A person 40 years of age would have a predicted max heart rate of 180
BPM (Beats Per Minute), 220 - 40 = 180.
STEP 2: Your target heart rate zone is a range of 55% to 90% of your max heart rate.
Predicted Max Heart Rate x .55 = Low End of your target heart rate zone.
Predicted Max Heart Rate x .90 = High End of your target heart rate zone.
Example: A person 40 years of age would have a Target Heart Rate Zone of 99 to
162 BPM (Beats Per Minute); 180 x .55 = 99. 180 x .99 = 162.
For additional conditioning
guidelines and to set up
the target heart rate for
programs, the chart to the
right provides a reference
to Target Heart Rate
zones estimated by age.
NOTE:
1. Press the Pulse Recovery button at any time to run the pulse recovery function, the pulse
recovery function can be ran during an exercise and while running another program.
2. Once the pulse recovery function is initiated the TIME will begin count down from 0:60
seconds down to 0:00, during these (60) seconds you will not be able to quit the pulse
recovery function. An “E” message will display in the pulse recovery value window of the
monitor when there is no heart rate signal detected or available.
