We covered all things physical therapy from her background to her passion for helping people move better and feel better. We talked about the key foundational principles of mobility work as a tool for injury prevention and movement prep. Stacie talked about the key exercises that should be included in a weekly routine, in order to optimize joint function and longevity.
