Mitoman Takes on American Ninja Warrior

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.
