The Myth of Cardio

Is cardio really as positive and necessary as we think?

We all have an idea of what cardio is. In one way or another, we've practiced it, as it's commonly recommended for improving our physical condition or in sports competitions. But is it really as beneficial as we believe?

Due to the lack of uniformity in its definition, the origin of the word, and a popular culture ingrained even in the professional sector that associates it with numerous benefits based on incorrect criteria or misinterpretations, cardio is probably the biggest myth in the world of training and physical activity.

In this book, Rubén Ávila invites us to discover what cardio is and to analyze, one by one, all its supposed physical, psychological, and emotional benefits. He helps us place it coherently within the practice of physical activity. With a rigorous, well-argued, and unbiased perspective backed by scientific studies, he explains what’s often not said about cardio and what much of the fitness world doesn’t want you to know.
