When helping a student learn a new skill, habit, practice routine, or making a mechanical change, I urge them to incorporate "4...3...2...1"! Here's how it works:
Let's say I am working on improving my impact position (see video):
Step #1. Notice that I am rehearsing proper impact position...slowly...methodically....to learn the new position. I will rehearse this... 4 TIMES
Step #2: I am expanding the motion...a few small backswings...while maintaining proper impact position. I will rehears this... 3 TIMES
Step #3: I am expanding the motion to both the backswing and forward swing....still focusing on proper impact. I will rehearse this...2 TIMES
STEP #4: One strike of the golf ball, doing my best to incorporate proper impact position.
I will then completely repeat the process: 4...3...2...1 for the duration of my practice session.
The goal, over time, is to improve impact. The key here is "over time"...it WILL take time to develop the new habit. I must have confidence in what I am doing...how I am going about it...that I WILL get it...and it will work under pressure. "OVER TIME"!
No matter what you are working on...try this routine...."4...3...2..1". I will help!
