Albert Beckles won the 1991 Niagara Falls Pro Invitational IFBB at the age of 61. His last contest was when he was 62 and he still looked amazing.
There is dispute over Beckles' true age. Beckles refuses to confirm his true age for whatever reason.
Most likely he was born in either 1938-1940 not 1930. This would put him at 51-53 years of age in 1991. Still impressive.
Beckles is/will be 80 years old in 2020, not 90.
