With Lou out for this episode, Mark and Greg sit down to talk ground forces. Perhaps you caught Mark's video about the lesson Greg had about ground forces (https://www.youtube.com/watch?v=Eay0xd61fyY). In today's show, they talk about what it means to use the ground (hint: you are), how to use the ground well, and how wise use of technology can lead to big changes in your swing and improvements in ball flight—sometimes without thinking about how you're swinging at all.
