This book has been approved by TWiEA - The World Isometric Exercise Association (www.TWiEA.com). Nordic Walking and Trekking are two of the most popular forms of outdoor exercise available to almost everyone. Now, more people than ever before are spending an increasing amount of time outdoors and professional walk-leaders and individuals are choosing to enhance the experience by incorporating a Fitness on the Move(TM) approach. This means that more Nordic Walkers and Trekkers than ever are performing powerful and scientifically proven total-body isometric exercise sessions during scheduled walk breaks in almost any location. These improvised workout sessions primarily use walking poles as what we call IIEDs - Improvised Isometric Exercise Devices. With the know-how and improvised exercise ideas contained in this book, people are turning their walking poles into extremely effective go-anywhere multigyms. Also, walk-leaders and fitness professionals can use this book as a handy resource guide to devise new, fun-filled, and effective exercise sessions during group walking breaks. In the exercise section, there are arrows clearly showing the direction in which the force should be applied. NOTE: This is one of two companion books that together form a set. One book focuses on exercises that can be performed by individuals, and the other on exercises that can be performed in partner pairs. Since the background exercise science remains the same the introduction and relevant exercise science sections to both books are essentially the same. The important difference between the two companion books is the exercise resource section, with each book specifically focussing only on one aspect. NOTE: The authors, Brian Sterling-Vete and Helen Renée Wuorio are exercise specialists who have worked closely with the NHS Innovation Team at the Greater Manchester Mental Health NHS Foundation Trust on two major isometric exercise trials during 2020. This was an outstanding success and they are now moving into a third much bigger trial before looking towards an expansion into more sectors of the NHS across the UK. TWiEA will be involved to conduct isometric exercise instructor training programmes for key NHS staff.
