All if this
CrossFit’s Theoretical Hierarchy of Development begins at the base: nutrition.
Each level of the pyramid informs and supports every tier above it. Nutrition provides the essential fuel and cellular foundation required for metabolic conditioning, body control in gymnastics, power output in weightlifting, and ultimate ex*****on in sport.
Because nutrition is the most powerful factor fully within your control, its quality dictates the integrity of every higher tier. Optimizing this foundation enhances your physical capacity across all modalities while building a lasting buffer against chronic disease.
Build a solid base. Everything above it depends on it.
