Kayoom was born in Malaysia and raised in Australia. As a child, his parents enrolled him in Judo to give him an outlet for his endless energy, and soon afterward he began studying Tae Kwon Do to develop his striking skills. However, it was at the age of 18 that he discovered Brazilian Jiu-jitsu, eventually moving to Brazil to live, train, and teach, and ultimately earning his black belt under American Top Team’s Ricardo Liborio in Florida. Over the past several years, Kayoom has also focused himself on the art of Muay Thai, winning numerous championships in Thailand and Cambodia, and at one point being ranked among the top ten Muay Thai fighters at Bangkok’s Rajadamnern Stadium.
