Mental Fitness: The Skill Your Organization Is Already Paying For — But Not Building

Organizations spend billions each year on burnout, stress, and productivity loss — treating the symptoms of unmanaged emotions without ever teaching the skills that prevent those outcomes or minimize them when they occur. In 1825, America introduced its first physical fitness program; within 75 years it was a national norm.

Mental fitness is at the same inflection point. As co-founder and Executive Director of the University of Michigan Institute for Mental Fitness, Dr. Kross makes the business case that emotion regulation and inner-voice management are trainable, measurable skills, and equips leaders with the evidence-based tools to build them into the fabric of their organizations.

The Human Edge: Mental Fitness in the Age of AI

As artificial intelligence takes on more cognitive labor, a critical question emerges: what do humans bring that algorithms can’t? The answer isn’t a technical skill — it’s a psychological one. The people and organizations that win the AI era will be those who can manage the inner voice under uncertainty, regulate emotions when disruption is constant, and lead with clarity when everything feels unstable. Dr. Kross makes the scientific case for mental fitness as the defining human competitive advantage in an AI world, and shows audiences exactly how to build it.

Perform: The Science of Excelling When It Matters Most

What separates people who perform brilliantly under pressure from those who freeze or fall apart? It isn’t talent or experience — it’s the relationship they have with their own mind in the critical moment. Choking, freezing, overthinking aren’t signs of weakness; they’re the predictable result of a brain doing exactly what it’s designed to do at exactly the wrong time. From the lab to the locker room to the C-suite, Dr. Kross unpacks the science of why the brain undermines itself under pressure — and delivers specific, immediately applicable techniques for performing closer to your ceiling when it counts.

Chatter: The Voice in Our Head, Why It Matters, and How to Harness It

The conversations we have with ourselves are the most important we’ll ever have. Our inner voice — “the Swiss Army knife of the mind” — helps us plan, perform, create, and lead. But when it turns on us, it becomes chatter: the relentless loop of worry, self-doubt, and rumination that undermines performance and health, often precisely when the stakes are highest.

Drawing on compelling human stories and cutting-edge science, Dr. Kross gives audiences practical, immediately applicable tools to turn their inner voice from their worst critic into their best coach — and the clarity to know the difference.

Shift: Managing Your Emotions — So They Don’t Manage You

Emotions are information, not noise. The better we regulate them, the better we think, perform, and lead. The problem isn’t that people have difficult emotions — it’s that almost no one was ever taught what emotions are, why they arise, or how to change them.

Dr. Kross dismantles stubborn myths — that avoidance is always toxic, that negative emotions are the enemy, that willpower is the answer — and reveals a surprisingly wide science-based toolkit for changing how we feel: strategies that work even under stress, even without time, and even when the usual approaches fail. The science challenges what you think you know. The tools change how you operate.

Raising Mentally Fit Humans: What Every Parent, Coach, and Teacher Needs to Know

Children spend more than 15,000 hours in school learning to read, calculate, and compete. They spend almost none learning to manage the experience of being human: the worry before a test, the spiral after a loss, the voice that says they’re not good enough. The result is a generation struggling with unprecedented anxiety and emotional overwhelm.

With research that will surprise and stories that will resonate, Dr. Kross gives parents, educators, coaches, and healthcare providers a practical framework for building mental fitness in young people — and modeling those skills themselves.
