Two
words:
Muscle
Confusion.
By
providing
an
extensive
variety
of
different
moves
that
take
time
to
master,
P90X
is
continually
challenging
the
body's
muscles
into
new
growth.
The
more
you
confuse
the
muscle,
the
harder
your
body
has
to
work
to
keep
up;
the
more
variety
you
put
into
your
workout,
the
better
and
faster
your
results
will
be.
The
flaw
with
many
fitness
products
is
that
they
all
lead
to
a
"plateau"
where
the
body
becomes
accustomed
to
the
routines,
resulting
in
diminished
effectiveness.
P90X
avoids
this
plateau
effect
by
switching
things
up
to
keep
the
body
guessing
for
the
entire
90
days.
Which
means
IT
NEVER
GETS
EASY.
By
breaking
old
routines
and
opening
new
doors,
secondary
and
tertiary
muscles
are
constantly
being
activated
and
developed.
