In 2002, Greg Glassman published the article “What Is Fitness” in The CrossFit Journal, in which he laid out the Theoretical Hierarchy of the Development of an Athlete. Nutrition sits at the very foundation — it’s what builds everything else. One of the most famous parts of this writing is his prescription in “World‑Class Fitness in 100 Words”:

“Eat meat and vegetables, nuts and seeds, some fruit, little starch, no sugar.” CrossFit Fairfield+2BarBend+2

What Protein Does for Your Body

Food isn’t just about fuel — it’s also about building. Everything from your muscles to your brain and bones comes from nutrients you eat, especially protein.
When you work out, your muscle fibers undergo microscopic damage. Protein provides the amino acids needed to repair them, making them stronger.
As we age, maintaining muscle mass becomes one of the most important predictors of health, mobility, independence, and longevity.

Introducing the NO Bull Sh*t Challenge

We’re gearing up for our NO Bull Sh*t Challenge, and it’s going to be full of value. Here’s what to expect:

Daily Protein Fact: Every day during the challenge, we’ll share one interesting fact about protein — how it works, where to get it, myths vs. reality, etc.
Snack or Recipe Idea: Along with the daily fact, you’ll get a snack or recipe idea in the challengers’ app — simple, tasty, protein‑packed.
Over the course of the challenge, you’ll get 90+ different protein ideas. Plenty of variety so you can find what works for you, and stay motivated.

Why Learn More?

Because strength isn’t just what you do in the gym — it starts at the dinner plate. With better nutrition and smart protein choices, you set the foundation for not only short‑term results, but long‑term health.
