Welcome to another inspiring episode of "The Mental Mettle Podcast," hosted by Coach Matt Thomann. In Episode 127, we dive deep into the remarkable 30-year career of Klay Wheeler—a coach whose wisdom and adaptability have positively shaped countless athletes across multiple sports and generations.

The Unsung Impact of Assistant Coaches

Klay Wheeler’s journey is a masterclass in the power of the assistant coach. Having served under various head coaches and in nearly every role—basketball, baseball, softball, football, track, and even scholar bowl—Klay sees the job of the assistant as making the head coach’s job easier, supporting communication, and finding ways to fill gaps in the program. Klay’s approach highlights the importance of being a chameleon: “You have to figure out where the gaps are, what needs to be fixed, and how you can help. You just have to pay attention and add value wherever you can.” This mindset not only eases the burden for head coaches—it creates better experiences for athletes and pushes programs forward.

The Assistant as Culture Builder

Wheeler emphasizes that assistant coaches are often the “good cop,” bridging the gap between head coach intensity and player connection. He believes that effective assistants help cultivate a positive, connected culture where athletes genuinely want to be. In his words, “If you are not making this somewhere they want to be, and you’re not making it beneficial, they won’t show up in the first place.” In the post-COVID era, where student-athletes face more options and new challenges, Wheeler insists coaches must adapt and actively foster environments where kids feel valued and supported.

Positive Psychology: Adapting to a New Era

Klay is clear: the pressure, anxiety, and reality of social media makes today’s athletes different. “The world that we lived in is not the world they live in.” He’s seen firsthand that teams with a culture of love, respect, and positivity grow not just participation numbers but also performance. Whether it’s practicing breathwork, focusing on praise, or shifting from marathon practices to targeted strength and speed work, Wheeler champions the role of mental health and confidence building in an athlete’s success.

Transforming the Weight Room and Training Mindset

A self-proclaimed “recovering meathead,” Wheeler shares his transition from old-school, high-weight training to a science-driven focus on explosiveness, speed, and functional movement. His willingness to learn, evolve, and implement new systems like “feed the cats,” speed sensors, and dynamic lifts has kept his teams ahead of the curve and helped countless athletes find confidence—not just in results but in the process. “Confidence is evidence. Once you get a little evidence, then you can build on it. When they see their numbers improve, they trust the process and believe in themselves.”

Nutrition, Recovery, and the Whole Athlete

Wheeler stresses that performance is more than reps and routines—athletes need to fuel their bodies, prioritize recovery, and build habits that last a lifetime. He advises boys and girls to “fuel, not diet” and to develop sustainable habits, like breathwork and sleep hygiene, that support their mind and body. This holistic approach, along with a relentless commitment to athlete wellbeing, allows his athletes to thrive well beyond the scoreboard.

Key Takeaways for Coaches, Athletes, and Parents

  • The most effective coaches are those who adapt, listen, and keep learning—even after decades in the game.
  • Culture and connection matter just as much as Xs and Os—coaching is about building places where kids want to belong and grow.
  • Evidence builds confidence: track progress, celebrate achievements, and use feedback to empower.
  • Take care of the whole athlete—nutrition, sleep, mental training, and positive support make the difference.
