Micros

Definition

Micronutrients—vitamins and minerals essential for health and performance. They're the supporting cast to macronutrients' lead role.

Example Usage

Even with perfect macros, deficient micros like iron and magnesium will compromise your training performance.

Origin

Derived from Greek 'mikro' meaning 'small'

Fun Fact

Only 9-15% of Americans meet recommended vegetable intake, meaning micronutrient deficiencies are extremely common despite not being obvious.

pace

The speed at which an athlete moves, or more accurately, the speed at which they promise themselves they'll sustain before inevitably slowing down. In running, it's the delicate balance between 'I can maintain this forever' and 'why does my chest hurt.' Coaches obsess over it, runners lie about it, and fitness apps judge you for it.

gymnastics

A sport where humans contort themselves into shapes that make regular people wince, requiring enough strength, flexibility, and body awareness to defy both gravity and common sense. Think of it as organized showing-off with judges holding up scorecards. Bonus points if you can stick a landing without your knees exploding.
