In part one of this three-part series, Dr. Mary Ellen Kramp is joined by Pilates educator Vanessa Pinkham to break down what diastasis recti actually is — and what it isn’t. They discuss how abdominal separation is measured, why it’s so common postpartum, and how ultrasound imaging helps assess muscle function beyond what can be seen or felt externally. This episode lays the foundation for understanding abdominal separation, pelvic floor involvement, and why proper assessment matters before jumping into exercise programs.
