Huge congratulations to Cameron for earning his IFBB Pro Card at Jr USA’s, taking 1st in D Class Men’s Classic Physique 🔥
A true example of what hard work, discipline, and consistency looks like inside and outside the gym. Proud to have you representing Metroflex and the energy you bring every time you step on stage.

Metroflex Oceanside and Flex Nutrition have officially parted ways and will no longer be operating together moving forward.
Over the past several months, we made sincere efforts to find a path forward that would allow the relationship to continue, but ultimately we were unable to come to a long-term arrangement that worked for everyone.
Effective May 1, the lease arrangement for Flex Nutrition came to an end, and they have now completed their transition out of the facility.
We appreciate the time they spent operating within Metroflex and genuinely wish them success in their future endeavors.
We also want to acknowledge that through all of life’s changes, Metroflex continues to feel the loss of Paul. He helped shape part of this gym’s story, and despite everything, he is missed.
Metroflex remains strong, focused, and fully committed to continuing to improve the experience for our members and community. We’re excited for what’s ahead.
Thank you for continuing to support Metroflex — the mission stays the same. 💪
