One of the greatest strengths of isometric exercise is its simplicity-you do not need expensive or specialist equipment to achieve a powerful total-body workout. That said, introducing a few well-chosen tools can add variety, challenge, and new dimensions to your training, and they do not need to be costly or proprietary.

This book explores the creative and highly effective world of Improvised Isometric Exercise Devices (IIEDs), showing how everyday items and basic climbing equipment can be transformed into serious strength-building tools. Limited only by your imagination and an understanding of biomechanics, IIEDs open up almost endless training possibilities.

At the centre of this guide is the daisy chain-a robust, versatile, and surprisingly powerful piece of equipment that lends itself perfectly to isometric training. The book details a wide range of improvised isometric exercises that can be performed with a daisy chain, alongside essential information on its construction, strength ratings, and safe use.

Clear, easy-to-follow illustrations include directional arrows that show exactly how and where to apply force, ensuring correct technique and maximum benefit from every exercise.

Practical, inventive, and grounded in real training science, this book is an invaluable resource for anyone looking to expand their isometric workouts with simple, affordable, and highly effective equipment-and to unlock new levels of strength using tools already within reach.

Required equipment: one or preferably two daisy chains and, if possible, a karabiner.

An interesting and crucial footnote is that the National Health Service (NHS) Innovation Team in Greater Manchester, England, has successfully trialled and deployed the Workout at Work system for employees.

The authors, Brian Sterling-Vete and Helen Renée Wuorio, worked closely with the NHS Research and Innovation Team to create a practical and effective system suitable for virtually anyone in any job.
