TWiEA™ members receive updates about the latest data about isometric exercise and access to the extensive online video-on-demand library of isometric exercises.


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 health, increase flexibility, and generally speed up recovery.

Workout At Work

The Workout at Work™ initiative is invaluable in helping ordinary people everywhere who do not normally exercise regularly to enjoy the healthy benefits of performing a total-body isometric workout while at work in as little as 70 seconds a day.  The British NHS has also embraced and employed this initiative.


To help proliferate the uptake and use of isometric exercise best practices there are a range of TWiEA approved books and equipment to help those seeking more information about it and some versatile and practical isometric exercise tools to use.

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.
