Welcome to USA Ninja San Jose!

Arnaldo is a former swimmer who put in hard work in the pool, always chasing excellence. Originally from Brazil, he’s built an adventurous life alongside his wife, a skilled softball player. Together, they’ve tackled skydiving and summited Half Dome in Yosemite—epic feats they’ve shared as a duo.

A dedicated dad to four daughters, Arnaldo has teamed up with them for Spartan races and OCR challenges, bonding over grit and fun. His own path—from years of competitive swimming to chasing Olympic dreams—taught him that character outlasts trophies. That insight fuels his mission today.

One of the biggest lessons Arnaldo learned as an athlete is the difference between a transactional coach and a transformational coach. He believes true coaching goes beyond skills—it’s about building confidence, resilience, and a mindset for life. That’s why he’s pumped to bring USA Ninja Challenge to San Jose. This vibrant community is the perfect place to create an environment where kids conquer obstacles, build character, and have a blast.

“This isn’t just about ninja skills—it’s about empowering kids to take on challenges in the gym and in life,” Arnaldo says. “I want to equip kids to live a life of excellence one obstacle at a time.”

And if you don’t see him coaching? He’s probably testing out the ninja obstacles himself—or getting beaten by his daughters in a race!
