A general view of coil

I am a firm believer in a firm RIGHT leg that the left shoulder turns around to create coil in the backswing. Then the right leg pushes forward which ever so slightly increases the torque. Then the body unwinds from the bottom up starting with the right leg, up the hips, torso, shoulders, and finally arms. Problems arise often when someone tries to circumvent this system. The MOST common I see is when the shoulders try to uncoil at the same time.

Just to clarify, the shoulders WILL turn when the hips turn, but they should essentially turn at the same rate until the hips begin to slow down. The shoulders do not turn in addition to the hip rotation at a simultaneous moment. Instead it is progressive.

Think of it like the tom tom drum from Karate Kid part 2. The ball on a string whips around a turning drum. If you turn the handle, the drum goes with it, and finally the strings whip around.

The trick to the golf swing is making sure you whip the arms around on the proper plane to swing the clubhead on a path where the ball lies.

Great, but two problems.

One, coiling is not "translating." Moving your left shoulder over or around your right leg is translation, not rotation. Coil is rotation.

Two, the hips don't just spin out. They push forward, along with the left knee, the left ankle rolls, etc.
