MEET THE FOUNDER & CEO
Hey, I'm
Keith Johnson!
founder of K3 Fitness and the creator of the
Square-Fit Pro Boxing & Conditioning Program
—a method built from decades of real-world experience in boxing, fitness, and performance coaching.
I began my journey as an amateur boxer and went on to open one of the first personal training studios dedicated to boxing performance in the early ’90s. Since then, I’ve trained world champion fighters, built wellness programs for companies, designed personal training studios, and helped professional athletes reach their peak.
Square-Fit PBC is my life's work—blending authentic boxing technique with modern strength and conditioning science to deliver results for clients at any level. Now, I’m passing that system on to you.
When you join the Square-Fit Certification program, you're not just learning a workout—you’re learning a proven method from someone who's lived it, taught it, and built businesses around it. If you’re serious about standing out, building your brand, and leading powerful, athletic training sessions that change lives—
I’ll show you how.
Let’s build champions together.
