Our Mission

Owner & CrossFit Coach

David LeGault

I found CrossFit in 2011 after a few years of competing in strongman and powerlifting.  I was looking for a new way to train that felt more beneficial to my overall health and well-being. I joined a CrossFit Affiliate in late 2012 and began coaching in early 2013. 

​

Since then with a foundation of the CrossFit methodology I have found my way into so many other fitness endeavors.  Completing an Ironman triathlon, several Spartan races, trail running, grappling, and even a physique (bodybuilding) competition.

The value of CrossFit to every aspect of my life has been immeasurable.  Possibly the best part about it has been doing it side by side with my wife and having our kids involved as well.  CrossFit has been truly life-changing for all of us.

Owner & Nutrition Coach

Karri LeGault

Wife to David, mom to Noella, Natalie, JJ, and 2 fur babies too! I grew up in the sport of swimming and was a D1 scholarship athlete. Post college, I was a middle school math teacher, but longed for setting fitness goals and working towards them. I taught group fitness (kick boxing and spin) for years. I competed in triathlons, ran multiple races including 2 marathons, and even dabbled in some obstacle course racing.

Nothing compared to CrossFit. My first class was nearly a full year after our second daughter, Nat arrived. It was perfect timing for me. I had lost myself a little while being home with 2 littles. I loved getting stronger, growing my confidence in the sport, and learning how to fuel my body better. During that time my passion for all things nutrition and wellness turned into a new career. I left public school education and I have spent the last 11+ years dedicated to helping people become better versions of themselves by making simple nutritional swaps that compound over time for themselves and their families. 

CrossFit & Endurance Coach

Stephen Wilk

I have been Coaching for CFK since September 2021. Before CFK I worked as a Personal Trainer for 5 years. I am avid Runner & Obstacle Course Race! CrossFit Knoxville provided me with community and friends upon moving from Florida. I have been able to grow as a coach and athlete here at CFK.

While coaching my goal is to make the experience fun and help athletes grow / progress within our community! coach CrossFit as well as specializing in Endurance Training / Strength & Conditioning for athletes. I take great joy in helping athletes improve their running technique or developing skills to help them in their given sport.

CrossFit Coach & Admin

CrossFit & Weightlifting Coach

Keith Roberts

I started CrossFit on June 1st, 2014. Prior to this day, I didn’t know anything about fitness, nutrition, or health, but constantly varied functional movements performed at high intensities changed everything about me and my life-for the better!

In August of 2019, I got my level 1 right here at CFK and In November of 2020, I earned my CrossFit weightlifting certification.
My main goal as a coach is to make fitness fun and effective and I hope every athlete I come in contact with walks away with a beneficial lesson that will better serve them on their pathway to health.

CrossFit Coach

Emma Freeman

My to fitness began in 2018 when I caught the CrossFit bug while attending the University of South Florida in my home state. CrossFit quickly forged a path to a passion for Olympic Weightlifting and the love of complex and technical lifts. Soon after, I pursued coaching in 2019, earning a USAW Level 1 Certification, followed shortly by Crossfit L1 and USAW L2 certifications in 2020 and 2021.

​

I found myself in Knoxville when I decided to attend UT for a Masters Degree in Sport Psychology. Ironically, I was able to put the degree to work personally after injuring my elbow at the USAW American Open Finals in 2021. I have worked my way back to putting up personal bests and continues to compete in Weightlifting.

Outside of coaching, I spend my time enjoying the newlywed life with my incredibly supportive husband Cameron, alongside our three dogs.

CrossFit Coach

Jenn Lucas

Hey there I’m Coach Jenn! I started my coaching journey back in 2009 with freestyle spinning (indoor cycling) classes. From there, I added more class formats and eventually became a Master Trainer with Les Mills. I started CrossFit in 2016 as a way to train outside the studio but quickly realized that it would be a part of my life for the long-haul. I got my CrossFit Level 1 in 2020 and the rest is history! 

In addition to my CFL1, I’m also an AFAA/NASM Personal Trainer and am also trained through the Metabolic Effect (Nutrition level 2) and the CrossFit Nutrition 1 course. I have a BS in Kinesiology as well.

My favorite thing about coaching is seeing people make small wins in the gym and in their lifestyle that moves them forward towards their greater health and fitness goals. Over time, those small wins add up to great things in people’s lives and it’s a joy to be a part of!

Weightlifting Coach

Greg Hartsfield

I brings over to 10 years of weightlifting experience to CrossFit Knoxville’s coaching staff. Starting with CrossFit, I realized with time that weightlifting was where my strengths lie. I played a wide variety of sports growing up, but once realizing my love for Olympic Weightlifting in 2011, I have not looked back.

​

I am passionate for my family and friends, and loves to try new things “I’m not afraid to get out there and put myself in unfamiliar situations,”. This propensity for new challenges encourages a love for working with people. “I tend to be overly friendly, and enjoy meeting new people. I love to talk about anything that others are passionate about.”

Foundations Coach

Brad Lokitz

I have been doing CrossFit for over 10 years, and found his passion for the sport after realizing I loved helping people through their health and fitness journey. With a 15 year rugby career behind me, I pride myself in being proactive about health and fitness.

When asked what my specialty within CrossFit is, I quotes Greg Glassman, the creator of CrossFit: “Nature will punish the specialist, I want to be a jack-of-all-trades and master of none. Specialization is for insects. I’m looking for breadth of experience, and anyone who is at all wise realizes that being a specialist represents a compromised position.”

​

While I may spend a lot of time at CrossFit Knoxville, I am also a scientist, holding a PhD in Polymer Science and Engineering as well as an MBA.

Gymnastics Coach

Matt Greiner

I have an extreme passion for lifting heavy things and teaching adults how to do tricks!  When I'm not in the weight room or competing on the platform, I am helping sick kids, hanging with my beautiful family, and just being a great human.  My Saturday Gymnastics class has officially achieved ‘Must Attend’ status.  It’s a place where average people learn to do amazing things!

Coach in Training

JJ LeGault

My favorite place to be is CFK! I love seeing  all my friends, telling jokes, and enjoying some cold FitAid!!!
