The Digital Therapeutic Specialising in personalised physical activity prescription + behaviour change science.
EXI: Exercise Intelligence
Exercise. It’s a powerful thing. It can improve our physical and psychological health. It can manage, treat, and even prevent certain conditions. For many, it’s a life-changer.
For years, research has shown the benefits of physical activity, but we’ve never had the tools to release its full potential. Healthcare professionals have been able to give recommendations, but not personalised prescriptions. Provide advice, but not monitor real-time adherence. There has never been a seamless way to use exercise as a targeted treatment for all.
We make prescribing exercise accessible, combining decades of scientific knowledge with pioneering technology to create the future of AI-powered healthcare. Our intelligent platform allows healthcare professionals to prescribe tailored programs in a way that’s easy, effective, and scalable. By uniting science with sophisticated motivational systems, we can achieve lasting behavioural change for all, including the people who need it the most.
This isn’t just exercise. This is EXI: Exercise Intelligence.
Our mission is to optimise care delivery by empowering healthcare professionals to prescribe personalised physical activity, the same way medicine is prescribed Exercise is Medicine.
Our vision is a world where physical activity and healthcare are integrated, enabling people to improve their wellbeing.
