WHAT DOES IT TAKE TO BUILD THE RIGHT TRAINING PLAN FOR YOU?
It starts with understanding you—not just your goals.
Every new client begins with our FunctionalFit Foundation Plan — a 1-month subscription designed to establish your foundation for long-term success.
During this month, we don’t simply hand you a workout. We take the time to learn how you move, what you’re capable of, how your current habits may be affecting your progress, and what you ultimately want to accomplish.
YOUR 1-MONTH FOUNDATION INCLUDES:
🎯 Goal Setting
Define your goals and establish a clear direction for your training.
🔎 Movement Screening & Breakout Assessments
We assess your movement and dig deeper when something requires additional attention.
⚙️ Movement Calibration & Coaching
We use hands-on coaching and movement modifiers to better understand how your body responds and help improve movement quality.
🥗 Behavior-Based Nutrition Plan
Your nutrition strategy is built around your actual habits and behavioral trends—not a generic meal plan.
🏋️ Your Individual Private Workouts
Receive workouts built around your goals, abilities, movement findings, and individual training needs.
🫁 VO₂ Field Testing
Establish a cardiovascular fitness baseline and track measurable progress.
AND YOU GET MORE THAN A WORKOUT.
Your 1-month subscription includes weekly private 1-on-1 coaching, weekly Ignite Boot Camp, and 24/7 access to our private training studio so you can get more out of your training between coaching sessions.
Prefer to train at home?
We can come to you.
FreddyFit services are available at our private studio or through in-home personal training.
WHY START WITH THE FOUNDATION?
Because your training should be based on information—not assumptions.
Your goals may be similar to someone else’s, but your body, movement, fitness level, habits, and starting point are unique.
We assess. We learn. We build. Then we train.
The FunctionalFit Foundation Plan is a 1-month subscription backed by our money-back guarantee.

15+ pounds down. 5.2% body fat lost. Confidence back. 💪✨
After having my second child, I felt like my body just wasn’t bouncing back. I was working out on my own, trying different training styles, but I still wasn’t getting the results I wanted.
On top of that, I was dealing with back pain from a rotated pelvis and poor gut health from my diet. I became so unhappy with how I felt that I wouldn’t even take a photo standing up.
That’s when I decided to stop trying to figure it all out on my own and started working with FreddyFit Personal Training
The results have been incredible—not just physically, but mentally. I’ve lost 15+ pounds, dropped 5.2% body fat, gained muscle, improved how I feel, and most importantly, got my confidence back.
Coach Freddy created a plan specifically for me, from my workouts to my nutrition. No cookie-cutter approach—just a plan built around my body, my goals, and my life.
This has been one of the best decisions I’ve made for myself and my family. ❤️
If you’re stuck, frustrated, or unsure where to start, sometimes the best thing you can do is ask for help.
Your transformation starts with that decision. 🔥
Wrapping up a long work week on a strong note. Every session fulfilled, every email answered, and every program completed. A productive week built on consistency, growth, and continued opportunities. Grateful for the continued momentum and the path ahead.
If I had to pick one exercise to do for the rest of my life, it would be the pull-up.
It challenges everything: strength, mobility, endurance, grip strength, and body control.

Great class complete! 💪
What makes our 55+ class unique is that every member receives an individualized program and has their own dedicated station. This allows us to coach each person based on their specific needs, abilities, and goals while still creating a supportive small-group environment.
We also incorporate weekly weigh-ins and guided stretching to help you stay accountable, track progress, and continue moving well.
Before joining the class, every member begins with a complimentary consultation. We take the time to learn about your health and fitness history, complete a movement screening, and determine the best place for you to start. From there, your program is customized specifically to you.
We currently have 3 spots remaining in this class.

34 years of martial arts. A career-threatening injury. And a return to the mat stronger than ever.
I have been a martial artist for 34 years.
It started the way it does for a lot of kids — I saw The Karate Kid, begged my mom to sign me up, and never left. Today, I'm a 4th-degree black belt, a national champion, and someone who has competed at a high level in Taekwondo and triathlon.
But even a black belt's journey isn't a straight line.
The Setback
During a tournament, I clashed knees with an opponent and partially tore my PCL. Kicks that used to be automatic now came with hesitation. Rehab got my body back in motion, but something deeper felt lost.
The Turning Point
That's when I started training at FreddyFit Personal Training. As a 4th-degree black belt, I wasn't initially convinced I needed functional training. But once I started, my perspective changed completely.
Things get harder as we get older, but functional training has helped me stay fit as I've aged. What surprised me most was how much room for improvement I still had, even after years at high level.
The Results
🦵 Rebuilt single-leg stability on the very knee that was injured.
🥋 Regained full rotation and power in my kicks.
🏋️ Hit personal records I never thought possible.
🏅 Qualified for nationals six months after returning, after nine years away.
🏆 Won a national championship in weapons.
🇺🇸🥋 In July 2026, made AAU Team USA.
Beyond the physical wins, I've experienced a mental shift in how I show up — for myself, my students, and my family.
A lot of people preach saving for retirement, but what good is that money if your health won't let you enjoy it? I can't put a price on having someone in my corner, investing in my health and my future.
In My Own Words
In my 40s, I'm not trying to turn back the clock — I'm proving the best years can still be ahead.
If you're a martial artist considering functional training, my advice is simple: do it.
Working with FreddyFit Personal Training has made me stronger — physically and mentally. We never know what we're capable of until pushed to our limits.
