Assembly Instructions

NOTE:
Using the Asuna Upright Bike will provide you with several benefits. It will improve
your physical fitness, tone muscles, and in conjunction with a calorie controlled diet, it
can even help you lose weight.
1. THE WARM-UP PHASE:
This stage helps to get the blood flowing around the body while loosening and the
muscles for workout. This phase will also reduce the risk of cramp and muscle injury.
It is advisable to do a few stretching exercises as shown below. Each stretch should
be held for approximately 30 seconds, do not force or jerk your muscles into a stretch,
if it hurts, STOP!
2. THE EXERCISE PHASE:
After regular use, the muscles in your legs will become stronger as a result the
duration & intensity of your workouts may increase based on your body’s tolerance to
physical activity, when increasing physical activity it is very important to maintain a
steady tempo throughout. The rate of work should be sufficient enough to raise your
heart beat into the target zone shown on the graph below.
This stage should
last for a minimum of
12 minutes though
most people start at
about 15-20 minutes.

Exercise Instructions

Physical activity during this stage should last for a minimum of 12 minutes, although
for most people it will take about 15-20 minutes for their heart rate to reach the target
zone.
3. THE COOL-DOWN PHASE:
This stage is to allow your cardiovascular system and muscles wind down. This is a
repeat of the warm up exercise e.g. reduce your tempo, continue for approximately 5
minutes. The stretching exercises should now be repeated, again remembering not to
force or jerk your muscles into the stretch.
As you get fitter you may need to train longer and harder. It is advisable to train at
least three times a week, and if possible space your workouts evenly throughout the
week.
MUSCLE TONING:
To tone muscles using the Asuna Upright Bike, you will need to set the resistance
level to high. This will increase the strain on the leg muscles, which will result in
shorter training sessions. As the work load is increased, it will decrease the required
time for the muscles to obtain an adequate workout. If you’re trying to improve your
fitness, you’ll need to alternate your training programs. You should start with your
usual routine, but towards the end of the exercise phase, the resistance should be
increased in order to make your legs work harder than normal. You may need to
reduce your speed to keep your heart rate in the target zone.
WEIGHT LOSS:
The most important factor here is the amount of effort you put in. The harder and
longer you work, the more calories you will burn.
