Tavi Castro

World Champion Athlete, Breath-Hold Diver & Founder, Poseidon Ascend

Tavi Castro is a modern mythmaker. An elite athlete, entrepreneur, and cinematic storyteller whose journey bridges the physical and the spiritual. A  Musclemania Junior Champion in both Europe and Britain, and the 2012 Musclemania World Model Overall Champion,  he has since redefined human limits through record-setting freediving feats, including a Guinness World Record for the heaviest deep dive at 132 feet (42 meters) on a single breath.  His evolution from bodybuilding to breath-hold diving reflects a deeper pursuit: merging sacred masculinity, mythic narrative, and nature into a singular, purpose-driven life.

As founder of Poseidon Ascend, Tavi leads immersive retreats that blend freediving, breathwork, and storytelling with ocean conservation, supporting Sea Shepherd’s mission to protect marine ecosystems.  He also helms Body Engineers, a performance lifestyle brand rooted in discipline and transformation.  Tavi is forging a new genre of athletic storytelling, one that invites audiences to explore the depths of both water and self. His work resonates across wellness, men’s mental health, and youth empowerment, making him a powerful cultural force for brands aligned with authenticity, impact, and mythic resonance.
