What is the rotary chair drill?

The "rotary chair drill" is a technique used in golf to unlock power in the swing by understanding the role of weight shift and rotation. It involves sitting on a rotary chair and twisting the chair. This approximates the signature move of the best players in the world on the force plate, which analyzes the exertion and balance of forces during a golf swing. The drill highlights the importance of the lead leg in facilitating a transfer from linear to rotational motion, thus amplifying rotational power. Dr. Greg Rose explains that while the rear foot initiates linear motion, the lead leg not only stops this lateral movement but also accelerates rotation. This understanding alters the typical belief that the rear foot is solely the 'gas pedal' and the lead foot merely a stabilizing 'brake pedal.' Instead, both legs have active roles in the rotational dynamics of a golf swing, with the lead leg serving as the 'gas pedal' for rotation 1.
