Our story began with Lee Trainor’s innovative idea, inspired by his personal experience with spinal stenosis and lower-limb weakness. From this, he designed and patented the SHUFFLER®, a portable seated exercise device created to support movement, confidence and everyday activity.

His vision was rooted in the belief that everyone should have access to exercise, regardless of age, ability or financial situation.

At Trainor Jim, we are passionate about breaking down barriers to exercise and promoting overall wellbeing. Our commitment to this mission led us to create affordable, portable exercise equipment like the patented SHUFFLER®.

We are dedicated to helping individuals of all backgrounds embrace the benefits of physical activity, and we are proud to collaborate with experts in the field, including Surrey University and the Royal College of Art.

As a participant in the NHS Clinical Entrepreneur Programme, our long-term ambition is to make accessible exercise equipment available to more people across the UK, including those who may benefit from simple movement support in everyday settings.
