How old is the youngest male and female bodybuilder?

As of my last update in October 2023, the youngest male and female bodybuilders can vary widely, with young athletes often participating in competitions. Typically, young male bodybuilders can start as young as 16, while female bodybuilders may also begin around the same age. However, specific records for the youngest competitors can change frequently due to new entrants in the sport and various competitions worldwide. For the most accurate and current information, it's best to check with bodybuilding organizations or recent competition results.
