About The OCR Underground
Science-Driven Coaching for Real-World Performance
Hi, I’m Mike Deibler, an online fitness coach and the founder of San Diego Premier Training.
For more than 20 years, I’ve helped athletes of all levels—from weekend warriors to elite competitors—reach their peak performance without breaking down their bodies. Over the years, I’ve seen too many athletes train harder, not smarter.
That’s why I developed the REST System, a science-backed approach built on four key pillars:
Recovery – Fueling your body and optimizing recovery strategies.
Energy Systems Development – Training smarter with zone-based conditioning built on physiology.
Strength Training – Building functional, obstacle-ready strength.
Tactical Training – Translating your fitness into race-day performance.
This system is the foundation behind all of my coaching programs—whether you’re preparing for your first Obstacle Course Race or looking to dominate your next hybrid competition. My goal is to help you train efficiently, perform better, and stay healthy for the long run.
My Background
In addition to running my coaching business, I’m deeply involved in education and the fitness industry:
- Owner of San Diego Premier Training, a personal training studio in Carlsbad, CA.
- Lead Instructor for Functional Movement Systems (FMS).
- Director of Education for Exercise Etc.
- Competitor. Have competed in OCR and Hybrid events in 2013.
- Professor of Exercise Physiology at Miramar College.
- Author of Fuel and Fire: Dominate Obstacle Course Racing with Scientific Training Strategies Fueled by Nutrition.
- Podcast Host of over 100 episode on the OCR Underground Show.
My Mission
Every athlete deserves a smarter path to success—one rooted in science, not guesswork. My mission is to simplify the complex world of training and help you build a strong, resilient body that performs when it counts. If you’re ready to train with purpose, perform with confidence, and not destroy your body in the process, you've come to the right place.
