CrossFit Founder Greg Glassman describes the current health crisis as “The Mess.” With the addition of CrossFit Level 1 Certificate Courses specifically for health-care providers, “we’re making an impact,” Glassman says.

Dr. Tom Siskron, IV, and Dr. Ken Sanders have attended the CrossFit M.D. L1 course, and they are on a mission to meld the medical world with the CrossFit world. Dr. Siskron manages CrossFit Medicus One, the first virtual CrossFit box dedicated to reversing chronic disease.
