In this episode of LifeLONG, Ethan Suplee sits down with Johnny Muresan—an endurance athlete known for his incredible weight loss transformation. Once an athletic kid, life and habits led him to nearly 500 pounds. He made the decision to change—and started running.
Follow Johnny on Instagram: @johnnygoesrunning
He’s since lost over 150 pounds—going from walking to running marathons by building his life around discipline, accountability, and long-term health.
Now, he’s preparing to run the London Marathon on April 26—and we talk about what it looks like to gear up while tapering down.
Join us for a conversation on weight loss, marathon training, food addiction, identity, and what it really takes to stay consistent—and stop negotiating with yourself.
Health is lifelong.
It’s built, not born.
