Registered Dietitian, Personal Trainer, and Author of Ruck Fit
Ruck Fit shows you how to build strength, resilience, and metabolic health using one of the most underrated tools available: walking with weight.
It’s simple. It’s effective. And it works.
You’re Not Failing at Fitness, You’re Missing the Right Framework
If you’ve tried diets, tracked macros, followed “perfect” plans, and still feel confused or stuck, the problem isn’t discipline.
It’s that generic advice ignores how your body actually responds to food and movement.
Ruck Fit provides insight to build strength and balance blood sugar without extremes, restriction or burnout.

Why This Book Is Different
Anyone can write a fitness book. Few combine science, lived experience, and real-world application.
I’ve helped hundreds of women cut through nutrition noise and escape fitness extremes—without sacrificing results.
Stop Second-Guessing Every Bite. Start Feeling Strong Again.
If you’re tired of dieting, confused by conflicting advice, and stuck in your head around food and fitness, you’re not broken. You just need clarity.
I help high-performing women understand what actually works for their body using continuous glucose monitoring (CGM) and simple, nature-based movement like rucking, so results finally make sense and stick.
