Dexter "The Blade" Jackson (born November 25, 1969) is an American retired IFBB professional bodybuilder and the 2008 Mr. Olympia bodybuilding champion and 2012 Masters Mr. Olympia. With 29 wins, Jackson has the most professional men's bodybuilding titles. He has the distinction of winning the Arnold Classic a record five times (2005, 2006, 2008, 2013, 2015). After winning the Arnold Classic in 2015, he proceeded to place second in the 2015 Mr. Olympia. He is from Jacksonville, Florida. He retired from professional bodybuilding following the 2020 Mr. Olympia. Biography Dexter's first NPC (National Physique Committee) competition was the NPC Southern States Championship of 1992, where he took 3rd. He first competed professionally in the 1999 Arnold Classic, Night of Champions, and Mr. Olympia contests, placing 7th, 3rd, and 9th, respectively. At the 2007 Mr. Olympia, Jackson placed 3rd and many critics said he would not likely place any higher. On September 27, 2008, he defeated the reigning champion Jay Cutler to become the 12th man to win the title, and only the second man since Ronnie Coleman to win both Mr. Olympia and Arnold Classic title in the same calendar year. Jackson has won the Mr. Olympia title once, sharing this distinction with Chris Dickerson (1982), Samir Bannout (1983), Shawn Rhoden (2018) and Brandon Curry (2019). 2008 was a great year for Jackson, as he won the Arnold Classic, Australian Pro Grand Prix VIII, New Zealand Grand Prix, Russian Grand Prix and the Mr. Olympia. Jackson placed 3rd in the 2009 Mr. Olympia contest. In 2012, Jackson placed 4th in the Mr. Olympia, then surprised everyone by winning that year's Masters Olympia at the age of 43 and then won his fourth Arnold Classic title in 2013. In 2015, Jackson showed he was still a force to be reckoned with at the age of 45 when he placed 2nd at the Mr. Olympia; his highest placing since winning the Mr. Olympia in 2008. In 2020, Jackson announced that he will compete at the Mr.Olympia and this will be his final show after competing professionally since 1999. He placed 9th at that show, the same placing as his Olympia debut in 1999. Jackson has been featured in many fitness and bodybuilding articles, including being pictured on the cover of Muscular Development and Flex magazine. He shot his new documentary DVD titled Dexter Jackson: Unbreakable with filmmaker Alex Ardenti of Ardenti Films
