He currently competes in the welterweight division of the Ultimate Fighting Championship (UFC), where he is the current UFC Welterweight Champion. Usman was also The Ultimate Fighter 21 tournament winner. As of September 27, 2021, he is #1 in the UFC men's pound-for-pound rankings.
As a wrestler, Usman primarily competed at 84 kilograms, and was a 2010 US University World Team Member. Collegiately, he competed at 174 pounds, and was the 2010 NCAA Division II National champion, a three–time NCAA DII All-American and a NAIA National qualifier.
Usman was born in Auchi, Nigeria. His father was a major in the Nigerian Army and his mother was a teacher. He has two brothers, Kashetu and Mohammed, of whom the former is a Doctor of Pharmacy and the latter is a mixed martial artist. Growing up with his mother and two brothers in Benin City, Usman struggled with the conditions in his environment during his childhood. Usman's father Muhammed Nasiru Usman, who became a pharmacist in the United States, brought his family into the country when Usman was eight years old, immigrating to Dallas, Texas.
Usman started wrestling in his sophomore year in high school, at Bowie High School in Arlington, Texas. Because Usman's wrestling coach at the time had trouble pronouncing his first name Kamarudeen, he got the nickname "Marty" when he joined the team and it stuck with him during his amateur wrestling career. After compiling a 53–3 record in high school wrestling and placing third at the Texas state championships, Usman wrestled alongside Jon Jones at the senior national tournament before leaving for college.
In college, Usman wrestled in Iowa at William Penn University for one year, where he was an NAIA national tournament qualifier in 2007, but was unable to attend the tournament due to a snowstorm; half of his team and his head coach, however, had left early for the tournament without him, which frustrated Usman and influenced him to leave William Penn. He later transferred to the University of Nebraska at Kearney (UNK), which had previously tried to recruit him under advisement of then-UNK wrestler Tervel Dlagnev, and subsequently helped the Lopers win their first-ever team title in 2008. Usman placed top three in the nation all three years he attended UNK and was a two-time national finalist. He became the NCAA Division II national champion at 174 pounds in 2010, finishing the season with a 44–1 record and 30 straight wins.
Shortly after his folkstyle career was over, Usman turned his attention to freestyle wrestling and became a resident of the United States Olympic Training Center, with hopes of making the 2012 Olympic team. Despite making the US University World Team in 2010, Usman was sidetracked by injuries and eventually abandoned his Olympic goal after failing to qualify for the 2012 US Olympic Team Trials, turning his attention to mixed martial arts instead. Former National Football League (NFL) star Christian Okoye, who has the nickname "The Nigerian Nightmare" trademarked, gave his blessing for Usman to use it.
