Training at a more intense pace (anaerobic exercise) is reserved for
athletes and requires special preparation.
After each workout, set aside several minutes to walk or run at a lower
speed, to slow down and gradually relax your body.

Cardio-Training Exercise.
Cardio-training exercise is a form of aerobics (conditioning the body in the presence
of oxygen) and allows you to improve your cardio-vascular capacity. To be more
precise, you will improve the tonicity of the heart and your blood vessels. Cardio-
training exercise carries the oxygen breathed in from the air to your muscles. It is
the heart that pumps this oxygen through the body and, in particular, to the muscles
being exercised.
7.3.
Controlling your heartbeat.
It is vital to measure your pulse periodically in order to control your degree of
exercising. If you do not have an electronic measuring device, follow this procedure:
To take your pulse, position two fingers: on the neck, or below the ear, or at the
inside wrist beside the thumb.
Do not press too hard: excessive pressure reduces the blood flow and can slow
down the heartbeat. After counting the pulsations for 30 seconds, multiply by 2 to
obtain the number of pulsations per minute.
Example: 75 pulsations counted in 30 seconds correspond to a heartbeat of 150
pulsations per minute.
