The Xfinity U.S. Gymnastics Championships – Senior Men's Day 1 is the opening competition session of the U.S. national championships for elite male artistic gymnasts, organized by USA Gymnastics. It takes place at the Mortgage Matchup Center in downtown Phoenix and features senior men competing across the six men's apparatus (floor, pommel horse, rings, vault, parallel bars, horizontal bar) as they begin to contend for national rankings and titles. The session serves as a high-profile domestic showcase of top U.S. gymnastic talent within the Olympic-style competition calendar.
