Jerryl has been a martial arts practitioner since he was six. His grandfather, who fought during World War 2 as a boloman, was a big influence to him practicing martial arts. He has trained in Tae Kwon Do, Inosanto Kali, Shito-Ryu karate, kickboxing, and Pekiti Tirsia Kali.
He began training at GAT St. Louis in 2012, earning the rank of Ninong and the fighting name of Panda. Although Pandas are assumed to be harmless, they can deliver a devastating bite if provoked.
