Introduction
John Hallett is a 4th Degree Krav Maga Black Belt, instructor, and founder of Rocky Mountain Self Defense & Fitness in Castle Rock, Colorado. For decades, he has trained everyday people to develop real-world self-defense skills, confidence, and mental toughness.
John’s teaching focuses on practical training, decision-making under stress, and building the mindset required to handle real violence, not sport competition.
He is also the creator of the ClearSky Self Defense & Fighting System, a structured approach to training that integrates striking, grappling, weapons awareness, and scenario-based decision making.
His philosophy is simple:
Train for life. Not trophies.
John’s Martial Arts Journey
John’s martial arts journey began in 1992, while living on Nantucket Island, where he first developed a deep respect for disciplined training and personal responsibility.
After relocating to Colorado, John continued training and eventually opened Rocky Mountain Self Defense & Fitness (RMSDF) in Castle Rock in 2005.
Over the years, thousands of students have trained under his instruction including:
• Adults seeking real self-defense
• Parents wanting safer families
• Teens building confidence
• Professionals carrying firearms responsibly
Through decades of teaching, John refined his methods into what is now known as the ClearSky Self Defense & Fighting System.
The ClearSky Self Defense & Fighting System
The ClearSky system was built from one core belief:
Under stress, you don’t rise to the occasion — you default to your training.
ClearSky training focuses on:
• Practical striking and fighting skills
• Realistic self-defense scenarios
• Decision-making under pressure
• Weapon awareness and control
• Mental toughness and resilience
The goal is not to create fighters for sport.
The goal is to create confident, capable people who can protect themselves and the people they love.

Philosophy
John believes self-defense is about far more than technique.
True confidence comes from:
• Discipline
• Experience
• facing hard things
• learning from failure
• showing up consistently
One phrase he often tells his students:
Train More. Suck Less.
It’s not an insult.
It’s a reminder that improvement comes from consistent effort over time.
