4th Ave Gym is a family-owned boxing gym in Yuma with roots dating to May 1981, when it was established by Yuma native David Haile and his family. Long recognized as a local fixture, the gym has built its reputation through decades of continuity, community ties, and steady stewardship. Originally associated with Fourth Avenue, it relocated in January 1991 while retaining the name that links it to its beginnings. The business expanded again in 2020 with a second location in the Yuma County Foothills, with a Somerton location also noted as forthcoming. Across its growth, 4th Ave Gym has remained defined by its long-standing local identity and enduring place in Yuma’s boxing community.
