You could ask 100 teaching pros that question and get 100 different answers. Still, you’ll find some consensus that the most challenging thing to teach in the sport is the release of the golf club. By release, we don’t mean throwing the golf club down the course. The term refers to physics. At a given point in every good golf swing, the player gives up control of the club and allows momentum to take over the swing.
Natural movement provides more speed and power than raw human effort, so releasing the club is essential for solid contact and maximum distance. Pros recommend swinging a towel or something flexible to get a feel of “swishing” a golf club through contact to teach this sensation.
