In March 2011, Anthony Robles won a national college wrestling title in the United States despite being born with only one leg. Relying on upper-body strength and a unique sense of balance, Robles went undefeated throughout the entire season and was voted the outstanding wrestler of the NCAA finals. He also holds the world record for the most pull-ups in one minute. Anthony Robles talks to Ian Williams.
