What is the main reason for using video analysis during on-course lessons?

Using video analysis during on-course lessons primarily allows instructors to document pre-swing errors and pre-shot routines. This approach is instrumental in identifying specific areas where a golfer may struggle, such as grip, stance, or alignment. By capturing these movements on video, both the instructor and the golfer can visually analyze and assess the swing mechanics in real-time, leading to more effective corrections and improvements.

Video analysis provides clear visual feedback, making it easier for golfers to understand their own movements. It can highlight patterns that may not be easily noticed during regular practice or play. Additionally, by documenting pre-shot routines, instructors can help golfers establish consistent habits, which are crucial for maintaining performance under pressure during actual play.

While improving overall fitness, comparing with professional players, and tracking progress over time are important aspects of a golfer's development, they do not directly address the immediate need for correcting swing mechanics and preparing for execution in real-time situations, which is the main advantage of using video analysis in on-course lessons.
