This guide comes from a long conversation between three women who train for a living in different ways: an ACE-certified personal trainer with a degree in exercise science and nutrition, a CrossFit Level 1 trainer who works in sports marketing, and a marathoner-turned-trail-runner who has injured, rehabbed, and kept going. Between them they have made almost every mistake below, which is exactly why the advice is practical rather than theoretical.

None of what follows is about training harder. It is about removing the eight most common ways active women quietly sabotage their own progress: eating too little, fearing post-workout food, dieting like a bodybuilder on stage, skipping strength work, ignoring the menstrual cycle, chasing someone else's body, and relying on willpower instead of structure.
