🥋 Martial Arts Journey: From Judo to MMA
Caio began practicing judo at age 6, coached by Sensei Emílio Moreira. He became a multiple-time state and national champion.
After losing a judo match by armbar, he was encouraged to add Brazilian jiu-jitsu to his training. Later, he also picked up Muay Thai, building a well-rounded base that would serve him in his MMA career.
🥊 Transition to MMA and Birth of Fighting Nerds
At 18 years old, Caio began training MMA seriously and had his amateur debut in 2014, fighting out of the Dojô James Adler in São Luís.
To pursue MMA professionally, he relocated to São Paulo, where he co-founded the now-famous Fighting Nerds team with coach Pablo Sucupira.
Together, they crafted a training philosophy based on analytical thinking, precision, and scientific principles, breaking away from traditional methods.
