Strength training
Three guides on getting stronger without the usual overclaiming.
The frequency guide covers the minimum effective dose: how many sessions a week actually moves the needle, and why two can be enough. The creatine guide is specific about what the pooled evidence supports in women and what it doesn't — strength and performance look more consistent than the muscle-building claim the marketing leans on. Hyrox belongs here because four of its eight stations are loaded strength-endurance work, and undertraining that half is the most common beginner mistake.
Numbers and citations throughout, not a supplement stack.
