Article Outline

This deep-dive will cover the science of why traditional pre-workouts are designed for the wrong energy system.

1. The Three Energy Systems

  • Phosphagen (ATP-CP): Explosive power for 0-10 seconds (powerlifting, sprints)
  • Glycolytic: High-intensity for 30 seconds to 2 minutes (HIIT, CrossFit)
  • Oxidative Phosphorylation: Sustained endurance for 2+ minutes (running, cycling)

2. Why Gym Pre-Workouts Target the Wrong System

  • Beta-Alanine: Designed for lactic acid buffering in short bursts
  • Creatine: Optimized for ATP regeneration in explosive movements
  • High caffeine (300mg+): Creates jitters and heart rate spikes
  • Pump ingredients: Water retention that adds dead weight

3. What Endurance Athletes Actually Need

  • Nitric oxide for oxygen delivery (L-Citrulline, Beet Root)
  • Moderate caffeine with L-Theanine for sustained focus
  • Electrolyte balance for cramp prevention
  • Gut-friendly ingredients to prevent GI distress

4. The Mile 21 Approach

How we engineered a pre-workout specifically for oxidative phosphorylation—the energy system that powers every mile after the first few minutes.
