Book about the chaotic rise of CrossFit now available

The book 'The Glass Box' is now available at major bookstores. Author Calum Marsh dug deep into the history of CrossFit and describes how the organization grew in a way that did not always go by the book.

The story begins with Greg Glassman, the founder of CrossFit, and follows his journey from a small gym to a global movement. Marsh shows how the growth was accompanied by controversy, large sums of money, and far-reaching changes in the fitness world.

For CrossFit fans who want to better understand the background of their sport, this book looks like an interesting addition. The full title is: 'The Glass Box: The Shocking True Story of How CrossFit Broke the Rules, Made Millions, and Changed Fitness Forever'.
