In Which Comes First, Cardio or Weights?, science journalist Alex Hutchinson debunks the most common fitness myths and offers evidence-based answers. Throughout its pages, the author examines everything from the relationship between exercise and weight loss to the best strategies for building strength and endurance. This book is not just a training guide; it's an invitation to rethink everything you thought you knew about physical exercise.

What myths does this book debunk?

Hutchinson addresses questions every fitness enthusiast has asked themselves at some point. Do we burn more fat by training fasted? Do stretches prevent injuries? Is it necessary to exercise every day? Each chapter focuses on a specific myth and contrasts it with the latest scientific research. The author positions himself as an informed skeptic, willing to challenge popular beliefs even when that means going against the grain.

Additionally, several personal trainers recommend it as mandatory reading for their clients.

Key lessons from exercise science

The book is structured around specific questions, making it easy to consult by topics of interest.

Hutchinson also addresses controversial topics such as overtraining and the effectiveness of sports supplements, always with a rigorous and data-driven approach.

Pros and cons

Still, most agree that the fundamental concepts remain valid and that the book offers a solid foundation for making informed training decisions.
