The Verdict on The Underground PDX
Best for visiting athletes who want a CrossFit or HYROX class in a family-friendly, all-ages gym. Check the hours first, because weekday sessions run 6:00 am to 6:30 pm, Saturday times conflict between sources, and Sunday is closed.
Best for: Visiting CrossFit athletes, HYROX prep, Families with kids
