# Before the Ball Moves: How International Footballers Gain Their Advantage In this episode, Ian Renshaw and Professor Keith Davids explore the tension between practice tools and movement variability. Using Ian's experience with a golf putting mat as a springboard, they examine how template-based practice can encourage rigid repetition and ask whether this conflicts with Bernstein's principle of "repetition without repetition." The conversation covers degrees of freedom — how beginners freez...

# The Constraints Collective Podcast with Michael Richardson In this episode, Ian Renshaw and Keith Davids are joined by Professor Michael Richardson from Macquarie University, a specialist in ecological psychology and computational modelling. Mike's work sits at a fascinating intersection of mathematics, AI, and human movement — and this conversation explores what that means for how we understand and coach sport. The discussion covers how simple constraints generate extraordinary complexit...

# Round Up 10 — May 2026 In this month's update, Ian Renshaw and Professor Keith Davids catch up on the latest from the Constraints Collective world before diving into a rich discussion on skill adaptation, movement variability, and the dangers of template-based practice. Using Ian's experience with a golf putting mat as a springboard, they explore Bernstein's principle of "repetition without repetition" and ask whether tools that prescribe exact movement patterns work against the kind of fun...
