  1. The Stress–Recovery Cycle: The Missing Link in High Performance

    4 DAYS AGO

    The Stress–Recovery Cycle: The Missing Link in High Performance

    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. We break down the biology of stress and recovery, explain why burnout happens when recovery is missing, and discuss how elite athletes, business leaders, and high performers can build intentional recovery “doses” into demanding lives. 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.

    Find Your Purpose: How Meaning, Fulfillment, and Performance Actually Work

    What’s the point of success if you don’t feel fulfilled? In this first episode of You Don’t Know Jack, Dr. Jack Groppel and Dr. Haley Perlus explore purpose, meaning, and why they matter for performance, happiness, and resilience.

Together they break down: √ Why purpose is not “soft,” but essential for performance √ How meaning drives motivation, energy, and resilience √ Why fulfillment and success don’t have to compete √ How to find direction in your own life and career Whether you’re an athlete, professional, or someone searching for what’s next, this episode gives you a clearer way to think about purpose, growth, and living well while performing at a high level.

    Pressure to Perform: How Early Influences Shape Us

    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. In this conversation, they unpack how those early experiences influenced confidence, motivation, self-belief, and performance under stress, and how you can learn to use pressure as fuel instead of letting it create distraction, anxiety, or doubt. In this episode, you’ll learn: • Why pressure isn’t the enemy, it's the invitation (says Haley) • How early pressure experiences shape your mindset today • The difference between pressure that sharpens focus vs. pressure that creates anxiety • How to identify your own pressure story • Practical ways to convert pressure into clarity, confidence, and performance Whether you’re an athlete, leader, coach, or high performer, this episode will help you better understand your relationship with pressure, and how to work with it instead of against it.
