MEET YOUR TRAINER
Hey, I'm Justin Gratzfeld!
Before founding Unlocking Nutritional Longevity my journey was anything but ordinary. I started as a professional wakeboarder, coaching provincial and national-level athletes, but my path took an unexpected turn after sustaining multiple concussions. Those injuries led to permanent headaches and forced me to step away from competing.
Determined to stay active, I pursued a degree in kinesiology and became a firefighter, while continuing to play basketball five times a week and running 5K regularly. But life threw me another challenge when I contracted a rare brain infection from micro mold—a condition that only affects those with a history of concussions.
The infection left me fully paralyzed for 11 months. On April 26, 2021, I took my first steps with a walker. By July 16, I walked my first kilometer unaided, and in September, I ran 5 kilometers. By November, I had completed a marathon.
During this journey, I lost 80 pounds and dove deep into understanding what was happening to my body. The process of healing myself was overwhelming, navigating endless (and often conflicting) information about health and recovery.
That’s when I realized my purpose: to help others overcome their health struggles and take back control of their lives. I became a certified nutrition coach and personal trainer to simplify the path for others dealing with chronic illness, inflammation, or weight challenges.
Now, I’m here to guide you through your unique journey, helping you feel better, get stronger, and create a lifestyle you love because I know firsthand how transformative that journey can be. 🌟.

How to improve Knee Pain
Testimonials
I started training with Jake and the IEP team in 2023 and initially knew their approach to movement, training and performance was on a whole different level. No one in the LE or Mil training world was addressing this critical need in the way they do. The IEP team has the education, experience and individual hard skills to enhance any individual or departments training program. The practical performance based approach is something I support 100%. The way they address not only performance but combine it with individual hard skills is something that anyone can benefit from. I’ve been using their methods and programming in my own training and am extremely happy with the improvements I continue to make.
Matt Pranka
Xray Alpha LLC
I’ve trained with hundreds of instructors from all over the world, seen what they bring to the table, and while there are many good ones, Jake and the crew from IEP have truly found a niche that was lacking and filled it with solid knowledge. Despite being at the pinnacle of their craft, they’re still pushing their own growth and constantly evolving new ideas, drills, and training strategies... Plus, they’re just good dudes.
Joe Farewell
Instructor/Professional Shooter
Even having been athletic all my life and playing on a nationally ranked college lacrosse team, there were still many valuable pointers, tips, and lessons to be learned while working with Jake at In Extremis Performance. Regardless of your previous athletic experience, it’s well worth attending a course and tapping into their expertise on the topic of movement with a rifle or handgun.

IEP provides a unique framework for firearms and tactical mobility training. Their top notch instructors are able to effectively and efficiently show the correlation between efficient movement and effective firearm performance. I highly recommend this training to all law enforcement officers.
Dan Colasanto
Persident, TTPOA
Jake has been working diligently to bring the training industry something it’s never seen before and it’s very interesting. Instead of a shooting coach that can move, he’s a movement coach that can shoot. And I love it.
Mark Smith
JBS Training Solutions
The guys at In Extremis Performance understand efficiency and movement from a high level. If you are serious about improving your skill set with not only shooting, but in any athletic endeavor. I highly recommend training with In Extremis Performance.
