Most golfers practice for two hours and get worse. This is the exact 45-minute structure I give my own students — blocked work, random practice, and transfer pressure, in the right doses — so what you build on the range actually shows up on the course.
There's nothing magic about the number — practice doesn't stop paying at minute 46. But the quality of your focus is itself a skill you're working on, and most golfers struggle to hold it much past 45 minutes. Once focus slips, mistakes start creeping in, and an hour later you're rehearsing the wrong things without noticing. The plan splits that window into three blocks, each doing a different job for your brain.
One focus, one external cue, controlled reps. This is where technique changes start — and where most golfers wrongly spend their entire session.
Different club, target, and shot every ball. It feels worse and works better — the contextual interference effect is one of the most replicated findings in skill learning.
Consequences, scoring, one ball per shot — the conditions of real golf. This block is why the plan shows up on the scorecard instead of staying on the range.
