In today's episode, Mark again is analyzing motion capture data from elite players—this episode features Brooks Koepka. Today, Mark quizzes Lou and Greg (who, as always, loves making random guesses) about Koepka's hip turn in his swing. In the discussion that follows, the guys talk about the massive effects that hip turn can have on your swing—including things that Greg himself is working on in his pursuit of continued good results on the Champions Tour.Where to find us:Mark Crossfield's weekly newsletter: https://www.crossfieldgolf.com/subscribeMark Crossfield on Twitter: https://twitter.com/4golfonlineMark Crossfield on YouTube: https://www.youtube.com/user/4golfonlineLou Stagner's weekly newsletter: https://newsletter.loustagnergolf.com/subscribeLou Stagner on Twitter: https://twitter.com/LouStagnerGreg Chalmers on Twitter: https://twitter.com/GregChalmersPGAThe Hack It Out Golf Podcast on Twitter: https://twitter.com/HackItOutGolfLearn more about your ad choices.
