发明名称 Golf swing instructional device and method
摘要 A golf swing instructional cage for teaching a quiet lower body swing, employs a minimum of three body constraints: a rear constraint, a forward upper leg lateral constraint and a constraint at the rear of the rearward knee area such that when the golfer is located in the proper initial swing position proximal the rear constraint and knee area restraint and a short laterally spaced distance from the forward upper leg lateral constraint, avoidance of contact with the spaced forward upper leg lateral constraint during the golf swing instructs in quiet lower body control. Optionally a laterally spaced rear upper leg lateral restraint is also provided which, by avoidance of contact during the golf swing further instructs in additional quiet lower body control.
