clean and dry to avoid rusting.
•At regular intervals, apply a small amount of 3 in 1 oil all around the perimeter of
the flywheel where it comes into contact with the brake. This prolongs the life of
the brake and prevents the cycle from becoming noisy in operation.

EXERCISE INSTRUCTI NS
Using your IND R CYCLE provides you with several benefits, it will improve your physical
fitness, tone muscle and in conjunction with a calorie controlled diet, help you lose weight.
1. The Warm Up Phase
This stage helps get the blood flowing around the body and the muscles working properly. It
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, ST P.
2. The Exercise Phase
This is the stage where you put the effort in. After regular use, the muscles in your legs will
become stronger. It is very important to maintain a steady tempo throughout. The rate of
work should be sufficient to raise your heart beat into the target zone shown on the graph
below.

INNER THIGH
FORWARD

CALF / ACHILLES
This stage should last for a minimum of 12 minutes for most people
start at about 15
-
20 minutes

3. The Cool Down Phase
This stage is to let your cardio-vascular 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 T NING
To tone muscle while on your IND R CYCLE you will need to have the resistance set quite
high. This will put more strain on your leg muscles and may mean you cannot train for as
long as you would like. If you are also trying to improve your fitness you may need to alter
your training program. You should train as normal during the warm up and cool down phases,
but towards the end of the exercise phase you should increase resistance, making your legs
work harder than normal. You may have to reduce your speed to keep your heart rate in the
target zone.
WEIGHT L SS
The important factor here is the amount of effort you put in. The harder and longer you work
the more calories you will burn. Effectively this is the same as if you were training to improve
your fitness, the difference is the goal.
USE
The tension control knob allows you to alter the resistance of the pedals. A high resistance
makes it more difficult to pedal, a low resistance makes it easier. For the best results set the
tension while the bike is in use.
