This book has been approved by TWiEA - The World Isometric Exercise Association (www.TWiEA.com). TRISOmetrics(TM) is an advanced, science-based high-intensity exercise system that combines 3 scientifically proven exercise techniques into a powerful new exercise system. TRISOmetrics(TM) can be performed with or without equipment, making it ideal for use at home or when travelling, or it can also be used as part of a gym-based heavy exercise routine; the choice is yours. The TRISOmetric(TM) exercise system will deliver maximum strength gains and muscle growth in minimum time by following brief and precise exercise methods that engage the maximum muscle fibres during each exercise. The exercises demonstrated in the book have arrows showing the direction in which the force/movement should be applied/performed, it tells you which types of exercise should be performed first during a workout, how many, and for how long etc. to complete your workout and get the maximum results from it. The method focuses on precision and quality in each exercise you perform combined with high-intensity exercise, keeping exercise sessions short, infrequent, and effective. The system is ideal for people who do not confuse activity with accomplishment as most people seem to do when exercising. The TRISOmetric(TM) exercise system can also be performed with the Iso-Bow(R), the Bullworker(R), the Steel Bow(R), the Bow Extension(R), the Iso-Gym(R) or similar suspension trainers and with all gym-based heavy exercise equipment. 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.
