TRUE GRIT FITNESS
I’m so EXCITED you decided to step in here and take a look at what I have to offer you .
Here you'll find that burnout around trying to do all the right things is normal, but not where you have to remain.
Here is where I take your hand to help you steady yourself in a world that wants to sell you the latest life hack, magic supplement, or diet that claims to have finally cracked the code on fat loss. You’ve likely been let down by them before.
It’s noisy, confusing, pushy, and outlandish out there. What’s worse is it is intentionally designed to make you feel helpless through all the madness. What it needs to feel like is nearly effortless. Where even when challenges arise you have the answers to keep moving forward without feeling defeated.
There’s nothing broken with you, we all need some support from time to time.
Like when planting a new tree and we plant a post alongside it to lean on until it’s strong enough to stand alone. That’s what your relationship with your coach should look like.
Together, we design your health and wellness legacy. With a curated approach that goes beyond workout plans and nutrition, we work together to build up your resilience and cultivate a lifestyle that endures the test of time with empowering mindset work. And it all starts by meeting you where you are, making the whole experience pleasurable, even when the road gets bumpy at times.
Whether it’s with our high-touch 1:1 coaching or a done-for-you program (in the works), you’ll find I’ve designed them with the intention of overcoming the burnout you may have felt from trying it all.
If this all speaks to you, and you’d like a look inside, go for filling out the zero pressure application form. Because even showing a willingness to look at empowering your life is a huge WIN.This is not your average application. Let it inspire you and take you down a short path of introspection
You're ready for a process that honors your biology, your mindset, and your life

Let me introduce myself
My name's Kalish—and helping people has always been my north star.
From packing parachutes in my skydiving days to designing environments that shaped how families lived, I have taken many paths. I’ve been a military spouse, a mom, a small business owner, a mayor—and a survivor. I’ve overcome autoimmune disease and cancer. Health has never been a luxury for me; it’s been a mission.
Then I lost my dad to cancer...
True Grit Fitness was born from loss, grit, and purpose. I’m a certified Personal Trainer, Nutrition Coach, and soon-to-be Health Mindset Coach. My work blends science, soul, and structure to help you reclaim your health, rewrite your story, and build a legacy you’re proud of, and my unique approach makes it easier than you think.
Take a look around—I’m so glad you’re here.
Blue Skies,

TESTIMONIALS
What clients are saying
"If it wasn’t for Coach Kalish working with me I don’t believe I would have made it through the Hearst Castle Tour. I was able to climb steps, do down steps and I didn’t even stumble. I haven’t felt this strong in years. I was really proud of myself!
My chronic pain has gone away and people are noticing a change. "
Emily B.
Veteran
"I can bend down and tie my shoes! It’s been awhile since I could do such a simple task and I did it without even thinking about it. But what’s more important is my knee pain has gone away which gave me a noticeable limp."

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.

Frequently Asked Questions
Want to get started but have a few questions?
What services do you offer for personal training and nutrition?
We offer a comprehensive, whole-person coaching experience that blends personal training, functional nutrition, lab work, and mindset support.
Whether you're looking to build muscle for that sculpted look, balance hormones, restore energy, or break free from the cycle of starting over, I meet you where you are--then help you move forward with a plan tailored to your body, your goals, and your life.
Here's what that looks like:
-Personal Training: Custom fitness programs designed to build strength, resilience, and confidence -- whether you're lifting at home or in the gym. All plans are progressive, purposeful, and aligned with your current fitness level and long-term goals.
-Nutrition Coaching: Whole food, sustainable nutrition strategies that support gut health, blood sugar balance, hormone regulation, and real-world results. No crash diets! No one-size-fits-all templates.
-Mindset Integration: Because true change happens from the inside out. Together, we'll work on breaking mental plateaus, building consistency, and shifting the way you think about your body, habits, and health.
If you're looking for quick fixes, this might not be for you.
But if you're ready to rebuild your foundation and invest in long-term change, you're in the right place.
What is mindset coaching, and why is it part of the process?
Mindset coaching is about helping you shift the way you think, not just what you do. Because habits, behaviors, and consistency are rooted in your beliefs, self-talk, and mental patterns.
We use evidence-based strategies to help you:
-Identify the stories or fears keeping you stuck in a fixed-mindset
-Rebuild self-trust and confidence as we cultivate a growth-mindset
-Create sustainable habits that align with your goals and identity
-Break through barriers keeping you from building a happier, healthier life
-Move past perfectionism, all-or-nothing thinking, and burnout cycles
This isn't about telling you to just "think positive" or "push harder". It's about helping you develop the mental tools to stay consistent, compassionate with yourself, and in control of your progress -- especially when life gets messy.
How do you customize programs for individual clients?
Every client we work with brings a unique story, history, and set of needs -- and we honor that. Customization begins with a deep-dive intake process where we look at your goals, current habits, health history, lifestyle, mindset, and more.
We go over nutrition plans that are not diets, but nutritious and practical for you to stick with for the foreseeable future.
Workouts vary depending on your own level of fitness. We also do the least amount of work to illicit the maximum level of results which can look very different from what you may be used to seeing in the fitness space. Our workouts are not draining, and do not require you to be in the gym several days a week with endless amounts of cardio.
Your training, nutrition, and support systems are all built with intention -- nothing generic, nothing cookie-cutter. This is about creating a sustainable path that works with your life, not against it.
What kind of results can I expect, and how long will it take?
There is no "lose 20lbs in 20 days" quick fix crashes here.
Because when we prioritize health, aesthetics will follow. But when we prioritize aesthetics, health fails us.
Your results will vary based on your goals, consistency, and your body's unique needs -- but here's what you can count on:
-Physical Results: Strength gains, fat loss, improved muscle tone, better energy, and reduced inflammation
-Health Results: While we make no medical promises, we do find that our approach can aid in better digestion, more stable blood sugar, improved hormone balance, and increased resilience.
-Mindset Shifts: Greater confidence, more self-trust, fewer mental roadblocks, and the ability to stay consistent without burning out.
This is a long-term solution rooted in real science and real support. Most clients begin noticing shifts within the first few weeks as they begin to feel better, and see meaningful transformation over the course of 3-6 months -- with ongoing progress that lasts well beyond that.
Do I need prior experience with fitness or meal planning to work with you?
None whatsoever!
You don't need to be an expert -- you just need to be open and willing to start. We provide all the guidance, education, and tools you need -- including optional meal plans, designed by nutritionists, that align with your nutrition needs and lifestyle.
Whether you're brand new or coming back after a long break, We'll help you build confidence and clarity as you learn how to move, eat, and show up for yourself in a way that's realistic, supportive, and sustainable.
