"She Pivots," in partnership with Marie Claire, challenges the typical definition of success and explores the role our personal stories play in our professional journey.

You all know her as the hilarious exercise icon. But it was a traumatic encounter that led Robin Alzon to fitness. After being held hostage in a New York City wine bar, Alzon took up running during law school. He said, "One hundred percent [running] was a moving therapy," he said. And while I was running, something really strange was happening. It was awful. But after the run... I feel like a hero. And I wanted to live a life filled with that kind of feeling. And the Movement became a real tool to have that experience."

Initially, Arzon continued with his career plan and worked as a corporate litigation attorney. While she found fulfillment in being able to advocate for her clients, her heart was elsewhere. So she made the decision to leave the law firm to pursue a career in fitness. Her first job was as a blogger covering the Olympics in London. 'I slept on my friend's couch for three weeks during the Olympics,' she says. 'I reached out to professional athletes who are now my collaborators and friends. But I was very bold. I didn't even know what I didn't know. So I said, 'Hey, what's up?' 'I like to run. I'm not kidding, I did that all the time in London.'

That led to a job at Nike, which led to a job in the peloton. It was the dream job that Arzon had drawn on her vision board. Shortly after starting work, however, she was struck by a major health scare. I was feeling lethargic and tired," Arzon says. I did a blood test and found out I had type I diabetes. I had never done anything like this before, in physical labor, in front of a camera, and I had an ultramarathon coming up a few weeks after my diagnosis. And a few weeks after my diagnosis, I ran an ultramarathon.

Such resilience allowed Alzon to pivot successfully and push everyone to their best selves as instructors in the peloton. Alzon is not done yet. 'We have the ability to iterate, and I think that's very freeing,' Alzon says. 'I think it's really liberating because if you allow yourself to define the finish line, you can always change course. Pivoting for me is a beautiful conversation I have with myself. What if it could be better?
