High performance cannot exist without both stress and recovery. In this episode of You Don’t Know Jack, Dr. Haley Perlus and Dr. Jack Groppel explore why stress is not the enemy, but an essential part of growth, adaptation, and performance, and why recovery is what allows stress to actually work for you rather than against you.

From active recovery and energy management to sustainable performance in work and sport, this conversation reframes stress as a vital signal and recovery as a performance skill. Whether you’re an athlete, executive, or someone feeling stretched by life, this episode will help you understand how to train, work, and live in a way that supports long-term performance, not exhaustion. Topics include: • Stress and recovery as a biological cycle • Why burnout is a recovery problem, not a motivation problem • Active recovery vs passive recovery • How to incorporate recovery into high-pressure work environments • Sustainable performance in sport, business, and life  Subscribe for weekly episodes on performance psychology, resilience, leadership, and mental strength.  To learn more about Dr. Jack Groppel: https://jackgroppel.net/  To connect with Dr. Haley Perlus: https://drhaleyperlus.com/ 

Pressure is unavoidable, but how you interpret it determines whether it sharpens your performance or drains your energy. In Episode 2 of You Don’t Know Jack, Dr. Jack Groppel and Dr. Haley Perlus explore how early pressure influences, especially from parents and authority figures, shape the way we respond to expectations later in life. Both Jack and Haley felt pressure from their fathers, but in very different ways.
