Q: When the workload changes from week to week, are you taking into account the total for the week (e.g. climbing, strength, aerobic), or is it solely the workload in the cardio zones that changes week to week?
A: The volume progression is limited to the aerobic portion of the overall training load. Strength training is not well tracked with volume, whereas basic aerobic work is quite well monitored with volume alone. This is especially true when the strength workouts increase in weight rather then number of sets.
