Reigning Olympic champion Shawn Johnson has announced her retirement from gymnastics. The American won four medals at the Beijing 2008 Games, including gold in the balance beam.
The 20-year-old has had problems with injuries ever since, tearing left knee ligaments in a skiing accident in 2010, and said it has progressively got worse.
"My body is at the point where I need time to rest and retire so I can be healthy for the rest of my life," she said. Johnson continued to soar after Beijing, earning celebrity status in the US after winning 'Dancing With The Stars'.
