What tool can a teacher use to help a player identify the cause of losing clubhead lag too early?

A pressure platform is an effective tool for helping a player identify the cause of losing clubhead lag too early because it provides detailed feedback on weight transfer and balance during the swing. By analyzing the player's foot pressure and movement patterns throughout their swing, a coach can help the player understand how improper weight distribution can lead to premature release of the clubhead. This kind of analysis can pinpoint specific areas where a player may need to adjust their mechanics to maintain the desired lag, enhancing their overall performance.

Other options might not provide the same level of detailed biomechanical feedback. A training aid could assist with various aspects of the swing, while a launch monitor primarily focuses on metrics such as ball speed and launch angle rather than on the player's physical movements. A kinematic feedback system might also offer insights into body movement but would not typically focus on the specific pressure points that a pressure platform targets. Thus, each choice has its benefits, but the pressure platform excels at addressing issues related to balance and weight transfer crucial for maintaining clubhead lag.
