High-Level Thinking for High-Level Performance

At every level of sport, physical ability eventually evens out.
What separates good athletes from elite performers is the mind.

At Sly Walters Mental Performance, sport psychology is not just about coping with pressure—it’s about developing the mindset, habits, and internal standards required to perform at a high level. We work with athletes of all ages to build the mental qualities that lead to enhanced performance and, ultimately, elite and professional opportunities.

True performance starts with belief, structure, and clarity.
Athletes who learn to think, prepare, and respond like high-level performers give themselves a lasting competitive edge.

Our sport psychology approach helps athletes:

  • Develop confidence rooted in preparation and discipline

  • Improve focus, composure, and decision-making under pressure

  • Build resilience through setbacks and competition

  • Create professional-level habits, routines, and standards

  • Align their mindset with their performance goals

When physical talent is similar, it is the mental game that determines outcomes.
We train that part of the athlete with the same intention as the body.


Developing the Young Athlete’s Mind

Mental performance training is most powerful when it begins early.

Research consistently shows that combining physical training with mental development leads to stronger long-term performance, confidence, and overall well-being. Structured activity doesn’t just build stronger bodies—it helps shape stronger minds.

Through movement, training, and guided mental strategies, young athletes can:

  • Improve attention, focus, and learning capacity

  • Build confidence and healthy self-esteem

  • Reduce stress and performance anxiety

  • Develop creativity, problem-solving, and resilience

  • Establish strong habits that carry into sport and life

At Sly Walters Mental Performance, we help young athletes build the mindset, discipline, and emotional control needed to grow into high-level competitors—on and off the field.

“To train with Sly is to understand that the journey towards realizing your potential is never ending. Goals aren’t destinations, they’re mere stepping stones to higher and higher performance. You can always go further, faster, harder, smarter, or more economically. You can always elevate your game.”

“Working with Sly this offseason has been a pleasure! Within a short period of time he has opened my eyes and has been very helpful. Each session I had with Sly I walked away learning something new about myself from a physical and mental standpoint. Sly is really knowledgeable when it comes to the body and mind… his workouts push your physical and mental state to where it hasn’t been before. He trains you to be comfortable in uncomfortable situations. Thank you Sly for challenging me to push my limits and hitting me with knowledge that I use on a everyday basis not just in sport but life! Raheem Edwards MLS Chicago Fire”

Soccer | South Carolina University

I’ve been training with sly for over 3 years now for soccer. Looking back from the start to now has been an unimaginable transformation. Each session has been a level up from the previous and taught me to fight through the adversity in order to keep leveling up, and throughout each day I’ve not only improved my body but continued to learn how to improve certain aspects of my game mentally, on and off the pitch. Thank you Sly for helping me get to the next level, looking forward to achieving more of my goals within the near future.

Sly’s program is important because it allowed me to realize that I need to always believe in myself even if people around me don’t. By believing in myself I will grow as a soccer player and as a person. Sly taught me that giving up is not an option and to push myself to my limits everyday. He provided me different techniques that help me achieve my goal to become a professional soccer player. Thank you Sly.  You’re the bomb!

Swimming | University of Ottawa

I am a competitive swimmer and have been training with Sly for about six years. For my first three years I worked with Sly multiple times a week and saw myself rapidly grow as an autonomous athlete. I became more motivated and saw direct results in the pool. The following three years I have been away at university but still find myself trying to squeeze in a session or two (or three) whenever I return home to Toronto. I do this because training with Sly is the most mentally and physically challenging workout I have experienced. Each time, after Sly explains the specific workout, I think to myself “how am I supposed to do that?”.  But then Sly reminds me “I can over I can’t” and breaks down each component into an attackable task.  By the end of our workout I’m so proud of myself for having mastered what I once thought beyond my capabilities. So, thank you Sly, for showing me I have no limits, for making me proud of myself, and for causing those really hard workouts to be so much fun and truly desirable.

Training in your environment helped me out in so many different ways. You pushed my body so much, that the things I use to struggle in, has become so much easier. You’ve also help me have a better mind set and help me learn how to push through things when it gets tuff. Lastly, I’ve been feeling more explosive and agile. Your training methods are very challenging which helps athletes who come to you excel. Also the workouts you do are not really that common, because it focus more on the other muscles and not really for the bigger muscles groups. I feel like that helps me lot over all as well. Overall, I feel that I’ve took a huge step forward after coming to you this summer!
