Why Off Grid Training Works
We don’t guess. We train with purpose — and measurable results.
Here’s what sets Off Grid Athletics apart from hype-based coaching:
Movement First
We start from the ground up — prioritizing joint integrity, mobility, and biomechanically correct patterns so athletes build strength that actually transfers to their sport.
Performance-Driven
Whether you’re trying to jump higher, cut faster, or return from injury stronger — our methods are built to enhance real-world performance, not just rack up reps.
Built to Last
We don’t chase quick wins. We develop durable, resilient athletes with injury-resistant bodies that thrive under pressure and hold up over time.
Tested. Tracked. Proven.
Every athlete gets baseline testing and regular check-ins. You’ll see your progress in strength, mobility, and vertical — and know exactly how you’re improving.
MEET YOUR TRAINER
Hey, I'm Justin Gratzfeld!
Founder of Off Grid Athletics
I’m a performance coach, father, former pro wakeboarder, and someone who knows firsthand what it takes to rebuild a body from the ground up. After a devastating brain infection left me paralyzed for 11 months, I was told I might never walk again. Instead, I relearned how to move, trained myself out of chronic inflammation, and eventually completed a 50km ultramarathon.
Before the injury, I had a
42-inch vertical, competed at national & world levels in wakeboarding, and trained for elite performance. After recovery, I took everything I learned and created a system that combines real strength, honest movement, and resilience that holds up in the real world.
Through Off Grid Athletics, I now coach youth athletes across Alberta — teaching strength, mobility, injury-proofing, and explosive jump mechanics. I’ve worked with national-level athletes, coached dozens of kids to their personal bests, and specialize in turning overlooked rural athletes into powerhouses — whether they’re on the court, field, lake, or trail.
My philosophy is simple:
No fluff. No shortcuts. Just proven systems that work.
Rooted in Alberta grit. Built to last.

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.
