Jon Brown founded Empirical Fitness in 2019 with a simple mission: to help people achieve real results with real methods. His passion for fitness — and for cutting through the noise of bad advice — led him to create programs rooted in science, not fads.

At Empirical Fitness, we believe that muscle gains aren’t just about lifting heavier weights—they’re about building a strong, resilient body that supports your goals, inside and out. Our approach combines personalized programming with proven strategies to help you grow muscle, boost your strength, and increase your overall performance.

How We Help You Grow:

Customized Programs

Progressive plans designed to adjust with every milestone.

Accurate Goal Setting

No more guessing. We help you set smart, achievable goals with a clear plan to hit them.

Nutrition & Habit Coaching

No cookie-cutter diets here. You’ll get real coaching on what to eat, when to adjust, and how to build habits that actually stick.

In-Person & Virtual Options

Busy? Traveling? No gym? No problem. We’ll coach you wherever you are and adapt your plan to whatever equipment you’ve got.

The Method Behind the Muscle

The word empirical means “based on experience or observation, not just theory.”

At Empirical Fitness, that’s exactly how we train — using science, real-world results, and proven methods that actually work.
