I'm Liz McKenna - a certified personal trainer and strength coach based in Jacksonville, FL with over 10 years helping people build real, lasting fitness.
I work alongside each client to create personalized, performance-based training programs that align with their goals, while providing the education, coaching, and accountability needed to train with confidence.
My clients are what I call Everyday Athletes - people who are ready to commit, willing to do the work, and want to make fitness a part of their lifestyle. Not something they fight against.
"Simple and straight-forward strength training - not trendy."
Many clients come to me with a clear goal but confusion about the route. I cut through the noise and build programs grounded in fundamental strength - so you develop the knowledge to push new limits and keep progressing long after we work together.

Performance-based outcomes from Everyday Athletes who committed to the process.
"Finding LM Fitness has been my saving grace. I was able to focus on consistency through the 30-40 min at home workouts Liz developed for me. With consistency as my priority I was able to feel more confident in my movements and could feel myself getting stronger. The Evolve program was true to its name - every couple of weeks the scheduled workouts would grow and intensify alongside my personal progression. I felt challenged without feeling defeated. I gained the confidence to attempt exercises I had failed at in the past (push ups, bench press, and almost all other upper body movements). Liz's encouragement and praise is a steadfast motivator to keep going on the days I feel like I have nothing left to give. The Evolve program has helped my mindset that I don't have to show up at 100% each day, I just need to show up for myself in whatever way it looks like that day. Lastly, this program has helped me think of fitness as a benefit to my mind and well being - instead of working out as a means to have 'the perfect body'. I am so thankful I took the leap of faith to sign up and continue on with the Evolve program."
"Working with Liz has been a game-changer. As I age, I am concerned about injuries and losing muscle mass. Liz designed a tailored program that has helped me improve my form and build real strength, I'm lifting heavier than I ever have, and I feel so strong! If you're looking for a trainer who cares about your long-term strength and health, not just quick results, I highly recommend Liz!"
"Liz has a remarkable talent of meeting me where I'm at but also challenging me to do things with my body I never thought were possible. I came to Liz because I have always admired her fun energy and dedication to fitness. I never thought it would change my relationship to fitness forever. I have been more consistent at building habits to support my health with Liz. She has helped me to navigate physical and emotional setbacks that would have previously had me throwing in the towel. As someone who struggles to make time for myself, I find my 1:1 sessions with Liz as a can't miss hour to bring me back to center. Liz is a cheerleader and a challenger in your corner ready to get to work."
"I've been athletic my whole life — mountain biking, triathlons, hiking, and teaching yoga. Working with Liz McKenna for the past year has been an incredible experience. I have never been stronger, and I've gained a deep education about how my body actually works. Liz doesn't just coach workouts; she teaches you the why behind everything, which has completely changed how I move and train. She tailors every workout to your specific goals, so it never feels generic — it's clear she's paying attention to what you actually need. I also love doing the workouts through the app; it's so easy to follow and keeps me accountable in a way I haven't experienced with other coaching. This past year has been genuinely life-changing and empowering. I feel more capable, more confident, and more connected to my body than ever before. I can't recommend Liz's coaching enough for anyone looking to gain strength and confidence to move through the world better."
The Everyday Athlete is someone who is ready to commit and willing to put in the work consistently, regardless of current fitness level. I work with all ages and genders. If you're ready to invest in a 6–12 month plan and want to make fitness a lasting part of your lifestyle, you're exactly who I work with.

Yes, nutritional coaching guidance is available with all services when clients request it. I also host special nutrition guest speakers and presentations for deeper education, and provide a discount code to a meal prep partner.

Real strength and lasting results take time. A longer commitment gives us the runway to build fundamental strength, fine-tune your training, and make fitness a natural part of your life, not something you restart every few months.
