At the 2026 Unbreakable Health Retreat in Miami, Greg Glassman describes what he believes is the true source of many modern scientific, medical, and societal problems. While corruption, financial incentives, and institutional dysfunction are often blamed for today’s crises, Greg identifies these as symptoms of a deeper issue: a widespread failure to understand how science works and how knowledge is created.
Drawing on the history and philosophy of science, Glassman traces the shift from observation, prediction, and empirical testing toward increasingly abstract statistical methods and theoretical frameworks. He argues that this transformation weakened the ability of scientists to distinguish between ideas that accurately describe reality and those that merely appear credible within academic institutions.
The consequences extend far beyond research journals. From irreproducible studies and public health failures to the chronic disease epidemic and declining trust in scientific institutions—many of today’s most persistent problems can be traced to flawed scientific thinking. Meaningful reform, he concluded, will require more than better incentives or stricter oversight. It will require restoring scientific literacy and rebuilding an understanding of how genuine knowledge is produced.
Greg Glassman founded CrossFit, a fitness revolution. Under Glassman’s leadership there were around 4 million CrossFitters, 300,000 CrossFit coaches and 15,000 physical locations, known as affiliates, where his prescribed methodology: constantly varied functional movements executed at high intensity, were practiced daily. CrossFit became known as the solution to the world’s greatest problem, chronic illness.
In 2002, he became the first person in exercise physiology to apply a scientific definition to the word fitness. As the son of an aerospace engineer, Glassman learned the principles of science at a young age. Through observations, experimentation, testing, and retesting, Glassman created a program that brought unprecedented results to his clients. He shared his methodology with the world through The CrossFit Journal and in-person seminars. Harvard Business School proclaimed that CrossFit was the world’s fastest growing business.
The business, which challenged conventional business models and financially upset the health and wellness industry, brought plenty of negative attention to Glassman and CrossFit. The company’s low carbohydrate nutrition prescription threatened the sugar industry and led to a series of lawsuits after a peer-reviewed journal falsified data claiming Glassman’s methodology caused injuries. A federal judge called it the biggest case of scientific misconduct and fraud she’d seen in all her years on the bench. After this experience Glassman developed a deep interest in the corruption of modern science for private interests. He launched CrossFit Health which mobilized 20,000 doctors who knew from their experiences with CrossFit that Glassman’s methodology prevented and cured chronic diseases. Glassman networked the doctors, exposed them to researchers in a variety of fields and encouraged them to work together and further support efforts to expose the problems in medicine and work together on preventative measures.
In 2020, Greg sold CrossFit and focused his attention on the broader issues in modern science. He’d learned from his experience in fitness that areas of study without definitions, without ways of measuring and replicating results are ripe for corruption and manipulation.
