Metabolism:
The
sum
of the
physical
and
chemical
processes
in an
organism
by which

and
destroyed,
and
by which

available.

the
muscle
fibers

point
where
a muscle
can
no longer
contract
concentrically
while
exercising.
Muscular
Endurance:
Ability
to make
repeated
muscle
movements
against
a moderate
load.
When
your
goal
is muscular
endurance,
you
want
to be
able
to lift
a heavy
enough
weight
that
you
can
only
complete
12-16
repetitions
of each
exercise..
Muscular
Strength:
The
ability
of your
body's
muscle
to generate
force
in a
short
period
of time.
This
type
of activity
relies
on anaerobic
energy
allowing
you
the
short
burst
of energy.
When
you
increase
your
strength,
you're
often
also
increasing
the
size
of your
muscles
as well
as strengthening
your
connective
tissues.
This
can
help
avoid
injuries
and,
of course,
make
you
stronger
and
healthier.
