The X factor is a reference to the separation created between the upper and lower body during the backswing phase of the golf swing. This separation is a key component in correctly sequencing the golf swing. Additionally, this separation between the upper and lower body is a major source of power for the golfer. Unfortunately for many players, creating the X factor is very diffuclt thus resulting in a loss of power and potential sequencing issues in the downswing.

Physical dysfunctions in terms of limitations in hip mobility, segmental stability of the core, or thoracic spine mobility can deter from ones ability to create an X factor. Such limitations are best addressed through corrective exercise within a comprehensive golf fitness training program. A number of exercises such as Torso Backswings, Windshield Wipers, Kneeling Chops, and Kneeling Lifts are beneficial in correcting the aforementioned physical dysfunctions. Over time these types of golf fitness exercises can improve one's joint mobility and segemental stability thus allowing for the opportunity to create an X factor.
