Greg Lehman, a physiotherapist, chiropractor and strength and conditioning specialist as well as an avid skateboarder hops on the show to discuss movement optimism which he defines as recognizing the resiliency of humans.

We discuss many movements such as knee valgus, spinal flexion + rotation, & pronation and how they are not as evil as many propose them to be. Additionally we cover why these movements are often not harmful and why universities and research make them out to be the perpetrator without a true base.
