Power Athlete Radio Ep 837: Redefining Durability w/ Dr. Ben Skutnik
Dec 5, 2025
Durability is the hidden key to optimal performance, according to Dr. Ben Skutnik. He introduces a revolutionary framework that emphasizes real-world strength and resilience. The discussion dives into the importance of endurance metrics versus fresh-state performance, exploring cardiac drift and its impact on athletic performance. Practical advice like incorporating Zone 2 training and finish-fast protocols helps build crucial tolerance. Strategies vary for different sports, ensuring athletes can remain resilient and avoid breakdowns throughout their careers.

Episode notes
Durability Defined And Distinguished
- Durability is the time of onset and magnitude of physiological deterioration during prolonged activity.
- It is measurable and distinct from mental toughness or resilience.
Cardiac Drift Reveals Individual Durability
- Cardiac drift shows heart rate increases relative to power output during prolonged exercise and varies widely between people.
- Measuring individual cardiac drift reveals true durability beyond assumed average drift values.
Power Tests Uncover Hidden Drops
- Power-degradation tests (e.g., 3-minute all-out after prolonged exercise) show large individual declines despite small group averages.
- Some individuals can lose a third of power after prior moderate-duration exercise.
