What is Lie?

Lie is the increase or decrease in Lie (the angle between the club shaft and the ground) between the start of a stroke and impact with the ball, measured in degrees.

Assuming the putter face is flush with the ground at the start of a stroke, lifting your hands will increase Lie, spinning the ball away from you. Lowering your hands will decrease Lie, spinning the ball towards you. In a biomechanically efficient putting stroke, there should not be an increase or decrease in Lie.
