What is Applied Functional Science®?

Applied Functional Science® (AFS) is the common thread to all that Gray Institute® delivers. AFS is based on scientific truth – not theory – that strategically links to the most effective and efficient techniques for the individual. AFS influences and enhances the entire Movement Industry – performance / training and conditioning, prevention, and rehabilitation.


Gray Institute® is internationally acclaimed for its innovation, development, mastery, and delivery of Applied Functional Science®. While many others and other organisations teach “function,” Gray Institute® is both the authentic source and foremost authority.
