He explains why cardiorespiratory fitness is one of the strongest modifiable predictors of longevity, clarifies what zone 2 training actually represents and how it differs from higher-intensity work, and addresses persistent confusion around exercise volume, intensity, and time constraints. The discussion covers how to measure and track progress in zone 2, VO₂ max targets and age-adjusted goals, planning for the marginal decade, and how to balance zone 2 with higher-intensity training across different weekly volumes. Peter also outlines how cardio training should be tailored for beginners, experienced trainees, and older adults, with special considerations for women and guidance on avoiding the most common cardio-training mistakes.
