About Amber Shields · Jacksonville, FL

My mission: strength you can feel, movement you can trust, and a body that's yours for life.

I get you there by coaching the whole person. Training, nutrition, recovery, and daily habits are treated as one plan, built around your goal and the life you're living.

The gap

Most people are already putting in the effort. What's missing is a plan that fits them.

Generic programs hand everyone the same workouts. Traditional training pushes harder and heavier, and when something hurts, you're told to work around it. Nutrition gets handled somewhere else, if at all, and sleep, stress, and habits never come up.

So people piece it together on their own: a workout app here, a diet there, an old ache they've learned to live with. They work hard and still feel stuck.

I created the FSI method to close that gap.

How FSI started

Where the work began

After years of coaching people of every age and fitness level, a pattern kept showing up.

The clients who struggled weren't lazy. They'd just never had someone look at the whole picture: how they move, what hurts and why, and how they eat, sleep, and handle stress.

When those pieces are coached together, progress stops stalling. That approach became Foundational Strength Integration (FSI).

My story

I know what it takes to build real strength — and what it's like when your body won't cooperate.

I came to coaching as a competitive powerlifter.

Within two years, I was in two major car accidents. The second was a rollover in which I was ejected through the sunroof.

Coming back meant starting over. Getting strong again wasn't enough. I had to calm an overwhelmed nervous system and rebuild the way I moved from the ground up.

That experience shaped how I coach. I learned that the body works as one system, and that getting fit takes more than what happens in the gym.


Credentials & care

Your trainer, and your health advocate.

MS, Exercise Science CSCS 8+ years coaching Certified nutrition coach PhD student, Exercise Science

I hold a master's in Exercise Science, I'm a Certified Strength and Conditioning Specialist and certified nutrition coach, and I'm now pursuing my PhD in Exercise Science. I keep studying because my clients deserve coaching grounded in the best current research.

But the credentials aren't the heart of it. I care deeply about the people I work with. I'm your trainer, and I'm also your health advocate. When something is beyond what training can solve, I'll point you to the right provider. I'll help you prepare for appointments, ask better questions, and make sense of what your doctor tells you, so you can speak up for yourself with confidence.

Many of my clients have been with me for years, and that's what I'm proudest of.

Why clients stay

What sets this apart

One coach, the whole picture.

Strength training, mobility, nutrition, sleep, stress, and habits are coached together, so the pieces support each other.

I start by looking at how you move.

Every client begins with a movement assessment, so your program is built for your body from day one.

We work through pain, not around it.

Old aches and injuries get addressed as part of your training, so they stop holding you back.

You'll learn the why.

You'll understand your body and your program, so the progress you make is yours to keep.

A plan built for your real life.

Your schedule, your starting point, your goal. In person or fully online.

A health advocate in your corner.

I'll help you talk with your doctors, understand what you're being told, and find the right provider when you need one.

Coaching that lasts.

Many clients stay for years, because the goal was never a quick fix.
