The healing power of fitness goes far beyond physical benefits—for today’s guest, it’s a form of self-expression and a celebration of what the body can do. In this episode, host Nora McInerny sits down with fitness personality Ivylis Rivera, who shares her deeply personal journey of navigating life with Chronic Migraine while holding onto her passion for movement. Ivylis opens up about the struggle of staying active while facing the fear of triggering a headache or migraine attack and the resilience it takes to keep pushing forward—a resilience that carried her through the challenging journey of finding a Chronic Migraine treatment plan that worked for her.
