I will assign workouts based on training
zones. There
are five training zones, labeled 1, the easiest,
through 5, the most difficult, with one additional level for "all-out"
effort.
áZone 1 is
fairly light exercise. It is used for easy days, recovery workouts,
long slow workouts, and to improve overall health. It is also
used as a warmup and cooldown for harder workouts.
áZone 2 is
the "somewhat hard" zone. Zone 2 is used to improve
the hearts ability to pump blood, increase metabolism of oxygen,
increase cardiovascular capacity of muscles, tendons and ligaments,
and to improve fitness and endurance. A large percentage of your
weekly distance will be done in zones 1 and 2.
áZone 3 is
a good hard workout. This is the zone in which we exercise at
a good pace but still feel comfortable and still have the ability
to carry on conversation. Exercising in this zone teaches the
body to burn fat, improves endurance, familiarizes us with training
at a faster pace. This is a zone that feels terrific, and you
will feel as though you could continue forever, but you shouldn't.
áZone 4 is
the "very hard" workout zone. Exercising in this zone
increases tolerance to lactic acid, increases enzymes in the muscles
used for anaerobic metabolism, familiarizes us with the pace and
effort used for racing and time trials. For readers familiar with
heart rate training concepts, the LT (Lactate Threshold or Lactate
Turnpoint) falls within this zone. This point is also sometimes
referred
to as your A
T (Anaerobic Threshold), and also by its
more scientific term "Onset of Blood Lactate Accumulation"
(OBLA). It is likely that during a zone 4 workout, you will stray
over this point at times; you will learn to notice the feeling
of increasingly heavy arms. Learning to notice this feeling early,
and to get back below your OBLA, is a valuable skill. When this
happens, you can learn how to recover below, but still near, your
OBLA. With time, you can learn to identify that point as a very
specific heart rate.

Zone 5 is
'very very hard', and is reserved for only a few of the hardest
workout efforts and races. This range is beyond our lactate threshold
and is used to increase muscle tolerance to large amounts of lactic
acid, and to improve sprinting and hard, short effort ability.
áThe "all
out" or maximum effort work only appears in some very
short duration sprints. They are notable because of their infrequent
appearance in the schedules. The heart does not have a chance
to respond before the sprint is over, so heart rate is not a useful
guide for these intervals.
