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.

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.

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.

CTT-Solutions LLC
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.

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.

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.

Working with Susanna Birge over the past few months has been an incredible experience. From the very beginning, I was searching for a personal trainer who truly understood rehabilitation and range of motion training — someone who could help me recover from injury while building lasting strength. I’m thankful every day that I chose Susanna.
What stands out most about her is her patience, her dedication, and her genuine commitment to helping her clients improve. She doesn’t just guide workouts — she constantly looks for ways to help me move better, feel stronger, and regain confidence in my body.
Susanna is also a wealth of knowledge. I deeply respect her passion for learning and continuous growth. She’s always studying, researching, and finding new ways to enhance her craft — and it shows in every session. Simply put, she’s a bit of a fitness nerd, and I absolutely love that about her.
I highly recommend Susanna to anyone who wants to improve their functional strength, mobility, and overall fitness — especially those who want to progress at a sustainable, thoughtful pace. She’s not just a great trainer; she’s a true professional who cares about every client’s journey.

I’ve been training with Susanna for about 8 months now and am very happy with the whole experience. I’m stronger, more toned, and feel more confident. I find her coaching style to be both supportive and informative. She’s careful, experienced, and fun! I highly recommend her and Tune It Up Training.
