About Us

Our story began with Lee Trainor's innovative idea inspired by his personal experience with spinal stenosis and lower limb weakness, he designed and patented the SHUFFLER® to support mobility, strength and confidence, which are important factors in reducing fall risk” and promote active, healthy lives. 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 well-being. 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 ultimate goal is to make our exercise equipment accessible to NHS patients throughout the UK.
