Heart
rate
is
important
but
listening
to
your
body
also
has
a
lot
of
advantages.
There
are
more
variables
involved
in
how
hard
you
should
workout
than
just
heart
rate.
Your
stress
level,
physical
health,
emotional
health,
temperature,
humidity,
the
time
of
day,
the
last
time
you
ate
and
what
you
ate,
all
contribute
to
the
intensity
at
which
you
should
workout.
If
you
listen
to
your
body,
it
will
tell
you
all
of
these
things.
The
rate
of
perceived
exertion
(RPE),
also
known
as
the
Borg
scale,
was
developed
by
Swedish
physiologist
G.A.V.
Borg.
This
scale
rates
exercise
intensity
from
6
to
20
depending
upon
how
you
feel
or
the
perception
of
your
effort.
The
scale
is
as
follows:
Rating

Effort

You
can
get
an
approximate
heart
rate
level
for
each
rating
by
simply
adding
a
zero
to
each
rating.
For
example
a
rating
of
12
will
result
in
an
approximate
heart
rate
of
120
beats
per
minute.
Your
RPE
will
vary
depending
up
the
factors
discussed
earlier.
That
is
the
major
benefit
of
this
type
of
training.
If
your
body
is
strong
and
rested,
you
will
feel
strong
and
your
pace
will
feel
easier.
When
your
body
is
in
this
condition,
you
are
able
to
train
harder
and
the
RPE
will
support
this.
If
you
are
feeling
tired
and
sluggish,
it
is
because
your
body
needs
a
break.
In
this
condition,
your
pace
will
feel
harder.
Again,
this
will
show
up
in
your
RPE
and
you
will
train
at
the
proper
level
for
that
day.
