The National Health Service UK

Since early 2020 TWiEA instructors have been working with the British NHS Research and Innovation department to introduce isometric exercise as a valuable tool that can be used to help strengthen, improve overall public health, increase flexibility, and generally speed up recovery from long periods of bed rest.

Workout At Work

The Workout at Work™ initiative is invaluable in helping people who do not normally exercise to perform the easiest, fastest, and discrete equipment-free exercise system while at work in as little as 70 seconds a day.  This is a baseline-essential public health-related concept, even for those who do not enjoy exercise.   The NHS has also embraced and employed this initiative.

Books and Products

To help proliferate the uptake and use of isometric exercise best practices there is a range of TWiEA-approved books and equipment available. 

These help those seeking more information about the isometric and TRISOmetric exercise systems and provide a range of versatile and practical exercise tools to use.

Becoming a TWiEA
Certified Instructor

To help set and maintain the highest standards of instruction in all forms of isometric and TRISOmetric exercise, TWiEA™ has devised an instructor training course. 

This helps to ensure that those who teach these techniques do so to the highest standards possible 

If you are an exercise professional, a sports professional, a gym coach, a school or college sports coach, a martial arts grade (or equivalent) Brown Belt or above, a PADI Divemaster or above, or hold any other kind of professional qualification in coaching/teaching physical activity, then you are almost certainly eligible to apply to become a certified TWiEA™ instructor.

Currently, due to demand and expansion, TWiEA™ are not accepting new membership applications.  However, we hope to be reopening the application system soon. 

Our Mission

As part of our mission, TWiEA™ aims to provide those seeking to perform and teach isometric exercises with high-quality resources, tools, and online video instruction. 

In addition, accurate and objective assessment of books/printed material about isometrics and also isometric exercise devices/equipment, together with general information for TWiEA™ certified isometric exercise instructors.

The workout videos are great for parents on the go! I have twins, a full-time job, and it's very hard to make it to the gym with my busy lifestyle.

The isometric workout system is simple and easy to use. They show you step by step how to maximize your potential and how to get the best results. 

The workouts are time-saving and the results are immediate. My overall strength has improved and helps me maximize my workouts at the gym.
