# 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 functional variability that underpins real skill development. The conversation moves into degrees of freedom — how beginners freeze their movements and how skilled performers learn to exploit them — drawing on Ludovic Seifert's fascinating research with ice climbers and the 1964 work of AJ Templeton, who was quoting James Gibson on reading greens long before ecological dynamics had a name. They also celebrate the release of the Palgrave Handbook of Creativity in Sport, which features multiple contributions from the TCC community, and share updates on a skill adaptability series that's rapidly gathering momentum. --- If you're getting value from our podcast check out our membership options and coaching community at [www.theconstraintscollective.com](https://www.theconstraintscollective.com) where you can access podcast summaries, narrated presentations, early release podcasts and monthly online meet ups with experts from the Constraints Collective.
