Perfect for you if...

  • You're an athlete or fitness enthusiast who wants more than just a workout program, you're looking for a framework that addresses your whole self.
  • You respect military and law enforcement discipline and want to apply that mindset to your own training and life goals.
  • You're interested in functional fitness and want clear technique guidance alongside the mental and spiritual components that make it stick.

Maybe not for you if...

  • You're looking for a quick-fix diet book or a minimalist approach to fitness, this demands commitment across multiple dimensions.
  • You're sceptical of spirituality or mindfulness practices and want a purely mechanical fitness guide.
  • You prefer generic gym routines over structured 21-day programs with performance standards and scaling options.

About this book

Firebreather Fitness presents Greg Amundson's integrated approach to fitness that combines physical training, mental conditioning, and spiritual practice. Amundson, a former SWAT officer, DEA Special Agent, U.S. Army Captain, and founding CrossFit athlete and coach, draws on his experience as a recognized leader in functional fitness conditioning and anti-inflammatory diet. The program includes 21-day integrated training cycles featuring innovative workouts, mental drills, and warrior yoga. It provides over 40 exercises with technique photographs, performance standards for progression, and scaling options for different fitness levels. Beyond physical conditioning, the book addresses mental toughness training and spiritual practices. It covers goal-setting, pain tolerance, purpose and focus development, and mental state management. The guide combines practical advice, training methods, and Amundson's workout programs for athletes, coaches, law enforcement and military professionals, and those pursuing high-performance fitness.
