Why Train with Oliver Functional Fitness ?

I know what it feels like to be in pain, feel limited, and unsure where to begin. 

My journey into functional fitness didn’t begin in a textbook, it began on the road after a life-changing motorcycle accident in 2014. Physical therapy became my classroom, and movement became my mission. 

Today, I bring that lived experience into every client session, backed by over a 15,000 hours of coaching, more than a decade of hands-on results, and multiple nationally recognized certifications from NASM, ACE, and PTAG

I don't push you through burpees or make you sweat for the sake of it. I’m here to help you *move better, feel stronger, and live pain-free*, with real structure, real assessments, and real results. I specialize in: 

My Areas of Specialization Include:

  • Corrective Exercise: biomechanics, pain-reducing movement, post-rehab transition, and performance enhancement
  • Functional Strength & Mobility: building sufficient strength, balance, and VO₂ max to support life in your 8th, 9th, and 10th decades
  • Assisted Stretching & Flexibility Therapy
  • TRX Suspension Training
  • Blood Flow Restriction Training (BFR): clinically backed for muscle growth with light loads
  • Nerve Flossing & Desensitization Techniques: (sciatic, ulnar, radial, median)
  • Voodoo Compression Wrapping: for mobility, edema, and joint recovery
  • Weight Loss Coaching: evidence-based fat loss, habit change, and body composition

What You Can Expect

Every client receives a Comprehensive Biomechanical Fitness Evaluation—a full-body movement screen that identifies joint instability, compensation patterns, and muscular imbalances. That way, we train with precision from day one.

Because at OFFC, we believe:
“If you’re not assessing, you’re guessing.”

Below is the fitness structure we follow and implement at OFFC:

"Eustátheia": Find Your Foundation  

Stability. Control. Foundation. 

Master the basics, or the basics will master you.”

This is our starting point, not because it's easy, but because it's essential. In Eustatheia, we rebuild the body's ability to stabilize, self-correct, and move with intention. Whether you're coming back from injury, navigating chronic fatigue, or simply feel out of sync, this is where control returns. Reconnecting the brain and body.

We train the neuromuscular system to fire with precision. We improve joint positioning, core integration, and postural awareness. Movement becomes less reactive and more responsive. Less compensatory and more coordinated. You won't outlift dysfunction, and you won't outrun poor mechanics. 

Because without a solid foundation, even progress becomes a liability.

  •  Mindset Shift: “You don’t need to be perfect. You just need to be stable enough to move forward—with confidence.”

"Epimoní": Cultivate Your Capacity

Endurance. Repetition. Resilience. 

What you can do once with effort, you must learn to do daily with grace.” 

Once stability is restored, we train what sustains you, the ability to repeat, adapt, and recover without breakdown. This is where your body, and mind, learn to show up consistently under challenge.  In Epimoni, is where capacity is built. Not just the ability to move, but the ability to move again... and again. It's where stamina meets structure. 

Here, we train your muscular and aerobic systems to tolerate more volume, stress, and variability.  We refine pacing, improve movement quality under fatigue, and increase your body's efficiency at managing energy, breath, and effort. Just as importantly, this phase builds mental resilience, the ability to show up, even when it's hard. 

Because progress doesn't just happen once, it's earned over time, through repetition with purpose

  • Mindset Shift: “Discomfort is not the enemy. In Epimoni, it becomes your teacher.”

"Ischýs": Create Your Strength

Force. Tension. Control Under Load. 

Strength isn’t how much you lift—it’s what you can hold without breaking.”

 In this phase, we convert stability and endurance into power. Ischýs is where resilience becomes usable strength, not just in the gym, but in everyday life.

We train the muscular, skeletal, and nervous systems to tolerate—and produce—force safely and efficiently. You’ll build the capacity to lift, carry, push, and stabilize under load, with joints that track properly and patterns that hold up under stress. We focus on force production, bracing mechanics, and joint control without sacrificing movement quality.

But strength here isn’t just physical. It’s the ability to remain composed under pressure, consistent under stress, and confident in your capacity to meet the demands of life.

Because the stronger you are, the more freedom you have to live life on your terms.

  • Mindset Shift: “You’ll earn every rep—and it will show. This is where change gets real.”

"Dýnamis": Unleash Your Potential

Power. Integration. Mastery in Motion. 

Potential is not what you have—it’s what you can use when it counts.” 

Dýnamis is where everything comes together. After building stability, endurance, and strength, we now train for real-world readiness—the ability to move with intent, confidence, and control in any situation.

This isn’t about peak performance in your 30s. It’s about preserving capability for your 8th, 9th, and 10 decade.

We develop explosive strength, efficient transitions, and movement fluency under dynamic conditions. Whether it’s catching yourself mid-slip, lifting a grandchild, or hiking without hesitation, we prepare you to act, not react. You’re not just more powerful. You’re more adaptable, more agile, and more in command of how your body responds to life.

This is about mastery—not for the gym floor, but for the living world around you.

  • Mindset Shift: "You’re not training for now. You’re training so that your future self still gets to live fully."

Our Philosophy: Train Like You’re Going to Live to 100. This isn’t gym-floor personal training. This is corrective, assessment-driven coaching that restores movement, reduces pain, and builds lasting strength. We don’t chase quick fixes, we build biological longevity. We don’t guess, we assess and progress. We don’t just train for your 30s, we prepare you for your 80s, 90s, and 100s. Because if you’re fortunate enough to live that long, you should be strong enough to enjoy it.

Yes! What Is Virtual Coaching? Virtual coaching allows you to train with me from anywhere using FaceTime, Zoom, Microsoft Teams, or any platform you prefer. Whether you have a full home gym or nothing but a mat and a water bottle—I’ll tailor your workouts to fit your space, goals, and equipment. Since the pandemic, I’ve successfully transitioned many clients to virtual training. With over 10,000 hours of coaching experience, I know how to adapt in real-time, offer clear guidance, and keep your progress moving—even through a screen. Virtual coaching is more than convenient. It’s effective, flexible, and personal. If you're ready for expert guidance, accountability, and results—without leaving home—I’m here to help you succeed, wherever you are.

Oliver Functional Fitness is located in Middleburg, FL, where I’ve converted my garage into a fully functional, climate-controlled private training studio. This space is ideal for clients who prefer privacy and a focused, one-on-one training environment—no crowds, no distractions, and no gym anxiety. Prefer to train in your own space? I also offer concierge training, where I bring the session to you. Whether it’s your home, garage gym, or office, I provide high-level coaching in the comfort and convenience of your environment.

Bring comfortable workout clothes, athletic shoes, a water bottle, and a towel. I have water and sports drinks and a restroom.

To respect both our time, I require at least 24 hours' notice for all session cancellations or reschedules. Sessions canceled with less than 24 hours' notice will be charged in full. That said—life happens. That’s why I offer a “Things Happen” waiver once per quarter. If an emergency or unexpected situation arises, you can cancel without penalty—no questions asked. This allows us to maintain consistency and professionalism while still offering grace when it’s truly needed.

Functional training is about more than just lifting weights—it's about training your body to perform better in real life. Every exercise I choose serves a purpose: to reduce pain, increase movement efficiency, and improve long-term health. At OFFC, I use movement strategies and progressions that closely align with physical therapy principles—like neuromuscular re-education, joint stability, and postural correctio —all while staying within my scope of practice as a certified personal trainer. This means you get structured, science-backed programs that restore function and build strength, without the guesswork or gimmicks.

Sometimes, what you need isn’t another workout, a massage, or a quick spinal crack—you need guided, hands-on mobility work that actually addresses the root cause of your tightness or pain. I offer Assisted Stretching & Mobility Sessions focused on improving flexibility, joint range of motion, and movement quality. These sessions include: -Passive and active-assisted stretches -Soft tissue release techniques -Mobility drills and breathing integration -Education on movement habits and corrective follow-ups You’ll leave feeling looser, more aligned, and equipped with tools for long-term relief—not just a short-term fix.

I signed up with Zach because I was feeling aimless in my efforts to get fit and wanted to work with a professional to learn to do it in and effective and safe way. Over the six sessions I met with Zach he helped me to improve my form, posture and daily body mechanics in ways that empowered me to carry on the work even when he was not around. Every effort was made to make sure I was equipped to improve myself beyond the time I had paid for and he strikes an excellent blend of being considerate and uplifting while still pushing me out of my usual bounds when working out. Zach was also very flexible regarding scheduling and is incredibly efficient with the time allotted for and appointment. I will definitely be seeking him out again in the future when I'm ready to take my training to a new stage.

I was looking for a personal trainer that worked with people for back pain. I was thoroughly assessed for my pain and a custom program was created for me. We've been working together for 6 months and I am 100% better. I have very little back pain and I feel stronger and have more balance. Go see Zachary.

I plateaued for a while while I was weight lifting and took a chance with Zachary’s workout plan. Within three weeks I noticed a difference And have been making explosive growth again. At this point I’m on week 11 of his workout plan and have gone up in weight and noticed my arms and best getting bigger

What truly sets Zachary apart is his mastery in addressing pain relief and corrective exercises. As a corrective exercise specialist, Zachary wields a toolkit of techniques that seem almost magical. Chronic back pain that once seemed insurmountable has gradually faded into oblivion under his guidance. He has meticulous attention to detail, ensuring that bad lifting form becomes an anachronism, replaced with by fluidly, and precision not only creates results but also prevents injury.

Jessica R.

Had a great initial meeting with Zach. I can tell that he is very knowledgeable by the way he speaks. We have developed a plan that is targeted to the things I will personally need improvement on. I like that it’s not a cookie cutter plan like I would expect to get at most places. Even though it was clear that I would need a lot of help progressing towards my goals, Zach did not make me feel judged at all. Instead, Zach clearly laid out his expectations of me to get me in the right head space for the work we would be doing. I signed up for a package so I got a flexibility, mobility, strength, and fitness assessment. I also had my weight and measurements documented. Very pleased with the ground work we have done thus far.
