About Us

GymDaddy, LLC was founded by Rio Grande Valley natives Billy J. Chapa and Jose Sifuentes out of a shared love for training, competition, and the culture that surrounds it.

Between us, our families, and the people closest to us, we've spent years around weightlifting, strength training, wrestling, Brazilian Jiu-Jitsu, and other forms of athletic training—from beginners just getting started to competitors at higher levels. That experience has shaped how we see fitness: it isn't just something you do for a season. For many of us, it's a lifestyle we want to continue for as long as possible.

That's also why we're interested in longevity, recovery, performance, peptides, and emerging research that may help people better understand their bodies and continue doing the things they love.

At the same time, we don't believe training has to be serious every second of the day. Progress takes discipline, consistency, and hard work—but the culture around training should still be fun.

That's where GymDaddy! comes in.

Our mission is to create products that reflect the personality, humor, mentality, and lifestyle of people who genuinely love to train. Whether you're lifting, grappling, competing, chasing longevity, or simply trying to become a better version of yourself, we want GymDaddy to be something you can identify with.

Train hard. Keep going. Have some fun with it.
