Living with mitochondrial disease means constantly managing energy, pain, and physical limitations. For teenager Sean Laughlin, it also means competing on American Ninja Warrior. Known as “Mitoman,” Sean joins Marcy with his mom, Christine, to share how he went from struggling with feeding intolerance and low energy to becoming a nationally competitive ninja athlete. They talk about the backyard ninja course his dad built, the adjustments that allow him to train with Mito, and the unforgettable experience of earning a buzzer on American Ninja Warrior while more than 40 friends and supporters cheered him on from the sidelines. Sean and Christine also open up about the realities behind those incredible moments. Sean relies on a feeding tube for his nutrition, lives with daily pain and exhaustion, and often needs significant recovery time after training and competitions. But ninja has given him something beyond competition: a community where he can simply be a teenager, friendships built around something other than his disease, and a chance to show other kids facing physical challenges what may still be possible. Now ranked among the top ninja athletes in his age group, Sean has his sights set on returning to American Ninja Warrior and taking his journey even further.

What happens when the machinery responsible for copying mitochondrial DNA doesn't work the way it should? In this episode, Marcy Young talks with Dr. Bill Copeland, leader of the Mitochondrial DNA Replication Group at the National Institute of Environmental Health Sciences, about the science behind mitochondrial DNA replication and what his decades of research are revealing about mitochondrial disease. Dr. Copeland breaks down complex topics including POLG and Twinkle mutations, heteroplasmy, mitochondrial DNA deletions, and the technique his team developed to detect deletions that conventional methods can miss. He also explains how this work is improving our understanding of disease and helping researchers identify new paths toward diagnosis and treatment. Dr. Copeland also shares what gives him hope about where mitochondrial disease research is headed. From new discoveries about the structure and function of proteins involved in mitochondrial DNA replication to promising small-molecule approaches being investigated by researchers around the world, the field has changed considerably in recent years. Just as importantly, Dr. Copeland discusses why training the next generation of mitochondrial researchers and connecting directly with patients and families are essential to moving the science forward.

Whether you're new to exercise or trying to regain confidence after setbacks, this conversation offers practical, evidence-based guidance to help you move forward. Dr. Mark Tarnopolsky is a neurologist, neuromuscular specialist, researcher, and internationally recognized expert in mitochondrial disease, exercise physiology, and nutrition. Drawing on decades of clinical experience and research, he shares why exercise should never be an all-or-nothing proposition, how patients can avoid common mistakes, and why personalized, sustainable movement remains one of the most effective interventions available for improving both healthspan and mitochondrial function.
