HRC Ultra Overview
Why Use
HRC Ultra
Workouts?
As mentioned in the Constant
HRC section, as you tire in the
last third of your workout, your
heart rate has a tendency to rise,
which Constant HRC addresses
by reducing workload.
However, exercisers who are
really serious and in very good
condition always let their heart
rates rise during the last third
of their workouts, usually to
very high levels. The HRC
Ultra workouts are designed
to simulate this kind of high-
intensity workout.
Do not attempt these work
-
outs unless you are certain
you are in good medical and
physical condition. Failure
to observe this warning may
result in shortness of breath,
dizziness, or death
