In 2018, 40+ year Veteran PGA Tour Member, Larry Rinker, published "The Upper Core Swing," The New Revolution. After screening over 1400 students with a Wright Balance Swing Analysis, over 75% of Larry's students have measured upper core. In every instance, this information has helped each student find their natural golf swing. Wright Balance has three swing models, upper, mid, and low core. Dr. David Wright believes that 2/3rd's of all male golfers are Upper Core. If you have been told your hips are not rotated enough at impact, you're coming out of posture and don't have enough forward shaft lean at impact, this ebook is for you because those three things are ok if you are an Upper Core Player.
