HRC ULTRA OVERVIEW
CHAPTER SEVEN: HEART RATE CONTROL
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
