Parkour with GREY G.

-Full Time Certified Parkour -Nearly a Decade of Experience -Learned Parkour Philosophy and Teaching Principles From The First Parkour Team The Yamakasi Hi there. I'm Grey, and I am a full time parkour instructor. It's what I love to do. I love sharing with people a way to become physically healthy, exercising anywhere they like without fancy equipment, and helping them become mentally stronger. Taking the leap. Discovering just how great they really are. Did you know the first personal trainers were Greek philosophers? They believed training the body was a way to put their philosophy, their virtues, into practice. I believe the same thing.
