Dee here still pouring out those nasty golf swing faults you need to correct.

“Chicken Winging”

35.55% Lead arm line doesn’t match lead arm- bent
64.45% Lead arm line matches lead arm- straight

Defined-

Is a loss of extension or breakdown of the lead elbow through the impact area. This swing fault makes it difficult to develop speed or power and tends to put excessive force on the outside of the elbow joint (tennis elbow).

Causes-

1.    Lead arm strength and lead side shoulder flexibility are paramount for a strong and fully extended lead arm at impact. If the arm is unable to rotate around the shoulder due to joint or muscular restrictions then chicken winging will dominate the pattern.
(tests- 90/90, Reach, Roll and lift, Lat test)

2.    If the downswing is out of sequence and your club is traveling on an over-the-top
path, the lead arm is almost always forced to chicken wing due to the direction of the
forces that are applied to it.

Other causes-
1.    Lack of understanding of proper technique
