In 1998 Menezes wrote the bestseller, “The Complete Guide to the Pilates Method”. (Published in the USA as “The Complete Guide to Joseph H. Pilates’ Techniques of Physical Conditioning” 2000, 2004) which became a training manual for trainee pilates instructors for the Institute for the Pilates Method (USA) and the Pilates Institute (UK). This established Allan as one of the leading thinkers and promoters of Pilates in the world. This book is still used as a basis for Pilates Theory as well as an inspiration to many of those deciding whether to pursue a career in the Pilates Method.
