This book has been approved by TWiEA - The World Isometric Exercise Association (www.TWiEA.com). One of the great things about isometric exercise is that it does not necessarily need any special equipment to perform a powerful total-body workout. However, using some simple equipment can add variety and dimension to any workout, also if you want to add some equipment to your workout then it does not have to be expensive or proprietary. Improvised Isometric Exercise Devices, or IIEDs, come in all shapes and sizes and are only limited by your imagination and knowledge of biomechanics. This means that basic climbing equipment can also become extremely powerful IIEDs and one of the most effective is the powerful and extremely versatile daisy chain. This book is a valuable resource listing many improvised isomeric exercises that can be performed with a daisy chain together with some essential information about daisy chains, their strength, and their construction. In the exercise section, there are also arrows clearly showing the direction in which the force should be applied. 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.
