Episode notes
Putting Video Revealed Hidden Faults
- Ian Renshaw filmed his putting and discovered he was coming inside the line and had his left foot turned out which caused pulls.
- He used video analysis with Lee Sullivan to reveal body orientation and putter path errors he hadn't felt.
Change The Task, Not The Technique
- Try adding task constraints instead of over-instructing technique to induce correct movement.
- Use simple tools (e.g., wood rails or a cricket stump) to change how you move and get immediate practice feedback.
From Rails To A Cricket Stump
- Ian tried wood rails but found them over-constraining and uncomfortable.
- He then used a plastic cricket stump to encourage a dipping shoulder action instead of trunk rotation and saw quick practice improvement.
