Ricardo began his martial arts and judo journey at age 4, before engaging in the Korean kicking art of taekwondo. He began practicing Brazilian jiu-jitsu when he was about 15 years old, which became the catalyst for him enrolling at the Carlson Gracie Academy in Copacabana, Rio de Janeiro, for Brazilian jiu-jitsu training. Here is where he has the opportunity to learn under Carlson Gracie, advancing his skillsets to impeccable levels, which earned him a respectable title as a BJJ practitioner/coach.

Ricardo is one of the top black belts produced by grandmaster Carson Gracie and holds a 6th-degree black belt in BJJ. Furthermore, he was the very first world jiu-jitsu champion in the super heavyweight division in 1996.
