Gray Cook is a physical therapist, lecturer, author, and instructor. He founded Functional Movement Systems which promotes the concept of movement screening and assessment. Gray has been a seminal figure in how we think about and quantify movement, and how we communicate the language of movement. We get into the state of children's health and what's missing from global agreement about movement after a child passes the 21 month old mark. We also get some great takeaways about free play and how a half foam roller can change everything.
