Why We Exist

Built For Every Fighter

Glove Up Fitness officially opened on August 3, 2019, built through the dedication, resilience, and vision of co-owners Jay Bellville and Ariana Jahja.

Boxing didn’t just shape our training—it changed our lives. Through some of life’s toughest challenges, boxing gave us strength, structure, and confidence. It also introduced us to a community that became like family. The relationships we built through training are some of the strongest we’ve ever experienced, and that’s what inspired us to create Glove Up Fitness—a place where others can experience that same growth, connection, and support.At Glove Up Fitness, we believe in more than just physical results. We believe in helping people step outside their comfort zones, push past limitations, and discover what they’re truly capable of—mentally and physically.

In 2022, Riley Just walked through the doors of Glove Up Fitness simply to try a class. What started as curiosity quickly turned into commitment. After training with Jay and JP, Riley developed a deep connection to the gym, the people, and the mission. November 2025, That connection led to a partnership, bringing new energy, structure, and vision to Glove Up Fitness.

This alignment of passion and leadership continues to strengthen Glove Up Fitness as a locally owned, community-driven gym—built on trust, consistency, and a commitment to delivering an exceptional experience for every member.
