“American Ninja Warrior” contestant Jimmy Choi was 27 when he was diagnosed with young-onset Parkinson’s disease after a routine medical exam. Today, Choi, 50, is an adviser to the Michael J. Fox Foundation for Parkinson’s Research who champions physical fitness and works to inspire others via public speaking and social media posts.
More than 1 million Americans have Parkinson’s disease, a neurological illness that can cause tremors, loss of balance, confusion and depression. Choi spent the eight years after his diagnosis in denial as his symptoms grew worse. After a mortifying fall, however, his perspective changed, and he embraced exercise — in a big way.
Since 2011, the Chicago-based former tech executive (he retired from full-time work in 2018, though he still works as a consultant) has run 16 marathons and earned three Guinness World records, the most recent in 2023 for consecutive double high five push-ups.
