In competitive amateur and professional bodybuilding, bodybuilders appear in lineups doing specified poses, and later perform individual posing routines, for a panel of judges who rank competitors based on criteria such as symmetry, muscularity and conditioning. Bodybuilders prepare for competition through a combination of dehydration, fat loss, oils, carb loading to achieve maximum vascularity, and tanning (or tanning lotions) which make their muscular definition more distinct.
Well-known bodybuilders include Charles Atlas, Steve Reeves, Reg Park, Arnold Schwarzenegger, Juliana Malacarne, Ralf Moeller and Lou Ferrigno. The winner of the annual IFBB Mr. Olympia contest is generally recognized as the world's top male professional bodybuilder.
The title is currently held by Phil Heath of the United States. The winner of the Women's Physique portion of the competition is widely regarded as the world's top female professional bodybuilder. The 2015 title is currently held by Juliana Malacarne, a Brazilian-born American IFBB Pro fitness and figure competitor and Ladies All-Star Wrestling Professional.
Since 1950, the NABBA Universe Championships has been considered the top amateur bodybuilding contest with many notable winners such as Steve Reeves, Bill Pearl, Reg Park, Arnold Schwarzeneggerand Lee Priest.
