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 Ren e 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 discreetly while at work to save valuable after-work time. This is the NEW, HUGE 800+ page 2025 edition of The Bullworker Compendium, which combines the latest, newly updated versions of both The Bullworker 90 Course and The Bullworker Bible into a single book. It also includes information and compression spring data for all new Bullworker Series 3 models, including the X5 Pro. This is Amazon's biggest printable book for its size. To save printing costs, we have eliminated duplicate sections; everything else remains the same. This way, we can offer both books in one large volume at a lower price than the combined price of the two individual books. Both books have big pictures, complete with useful arrows showing the direction to which the force and movement are applied. The Bullworker Compendium starts with The Bullworker Bible, and at the end of that, it progresses seamlessly into The Bullworker 90 Course. The Bullworker Bible is the definitive resource guide for all Bullworker users and the companion book for The Bullworker 90 Course. It is a complete, science-based, user-friendly guide to using the Bullworker properly to deliver maximum results. It also shows you how to use the Steel Bow effectively. These books tell you about essential repetition-compression and speed control, correct breathing techniques, how Hooke's Law of Physics applies to The Bullworker, and correct biomechanics to deliver the best results. The makers and distributors of The Bullworker approve the Bullworker Bible. This book can be used with the Bullworker Classic, the Steel Bow, Bullworker X5, Bully Extreme, ISO 7x, and the Bullworker X7. Required Equipment: A Bullworker Classic or a similar device. Recommended Additional Equipment: Steel Bow, 2 x Iso-Bows, and the Bow Extension or Iso-Flo.
