Episode notes
Cardio vs. Strength Training
- Cardio's primary benefits are internal, enhancing how your heart and muscles use oxygen.
- This differs from strength training, where external changes like muscle growth are more noticeable.
VO2 Max and Mortality
- VO2 max, measuring oxygen use during intense exercise, indicates cardiovascular health.
- Higher VO2 max correlates with lower risks of heart disease and overall mortality.
Optimizing Exercise
- Optimize exercise for intensity, duration, and frequency to maximize cardio benefits.
- High-intensity interval training (HIIT) can be more effective than longer, moderate exercise.
