Cory speaks with Expert Biomechanics Coach Joey D, who helped pioneer the unrecognized field of golf-specific fitness training over 20 years ago and has recently been working with 2020 FedExCup and Masters champion, Dustin Johnson. Borrowing from sport-specific physical training protocols used in other professional sports, Joey developed a methodology for golf and has helped players Vijay Singh and DJ reach the No. 1 position in the Official World Golf Rankings. In 2010, Joey authored a book on golf fitness training and biomechanics, Fix Your Body, Fix Your Swing.
