World Class Coaching
The Gainslinger Protocol
The game has changed….
Gone are the days of just putting in the seat-time and training hard. Everyone does that. As the sport continues to elevate, the athlete must learn to adapt…… or get left behind.
Excellence in sports has always been a function of 3 things: Mastery of skill, a well adapted/conditioned body, and the ability to manage ones own mind. To compete at the highest level….. proficiency in all three areas is no longer optional.
At Gainslinger Human Performance, we specialize in the development of racers at each level by focusing on the foundational principles responsible for mastery of the Mind, Body and Craft.
Our athletes achieve transformational progression and performance gains by utilizing a reliable and repeatable framework that maximizes skill learning, efficient training and deals with matters of the mind.

This is not another day at the track spinning laps with a few tips and tricks; This is a complete overhaul of how you engage with the sport of motocross and will fundamentally change how you see your potential as a racer.
Here’s what you can expect
Phase 1: Primer (Zoom)
Success never occurs by accident, intention is required. Before you even gear up you will have clarity on exactly what you can expect and what will be expected of you.
To accomplish this and maximize precious seat time. We will meet via zoom ahead of the class to introduce the concepts you will be learning and ensure that your mind, body and equipment are fully prepared to engage.

- On-Track Drills: Real-time correction and observation.
Phase 3: Review & Strategy (Zoom)
After the dust settles, we will review observations from the clinic and establish your Personal Racing Development Program to ensure the breakthroughs you personally experienced were just the start.
