In Part 6, MacKenzie introduces the Diesel Weasel, his CrossFitting dog, who pulls him on his skateboard or bike. He uses her to demonstrate running posture.
“In her movement, it’s the same with our movement,” MacKenzie says. She lands her feet underneath her and maintains a tight midline. It’s all the same principles with how the body works.”
MacKenzie also draws a parallel between his dog’s paws and barefoot/semi-barefoot running for humans. Without proper conditioning—starting slow and working up to longer distances—both people and dogs can destroy their feet.
He ends with discussing how midline stabilization is important for injury prevention.
