The isometric exercise system has been successfully trialled and deployed for employees by the National Health Service (NHS) Innovation Team in Greater Manchester, England.
The authors, Brian Sterling-Vete and Helen Renée Wuorio, worked closely with the NHS Innovation Team to create a practical and effective system suitable for virtually anyone, even if they wish to exercise discretely while at work to save valuable after-work time.
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, and if you want to add some equipment to your workout, 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 and some essential information about daisy chains, their strength, and their construction.
In the exercise section, arrows clearly show the direction in which the force should be applied.
