About 2000 years ago people did gymnastics for fun. In 1881 the International Gymnastics Federation was formed. The first competition was the 1896 Olympics in Greece. The German gymnasts dominated everyone and they almost won all the medals.
Gymnastics is the most dangerous sport in the world. By simply missing the bar you could fall and dislocate some joints. If you were to be doing an aerial and you jump to low you would try to put your hands down but you miss and land on your head. Flick Flacks are one of the most dangerous moves because you can miss the ground and land on your chest. That is why people start with simple moves.
There has been a lot of world champs in gymnastics. The 2013 champs were held in Belgium. Kohei Uchimura won the men's competition with a total of for medals. Simone Biles won the women's competition also with for medals. The 2012 champs were in London,the most successful nation was China. There has been lots more championships in time so I only doing two.
Gymnastics is helpful for your core muscles, arm strength, flexibility and self confidence.
I also think that gymnastics needs patience because if you rush into big tricks you could end badly. Most people in my gymnastics class are starting to do Aerials, Flick Flacks and back-flips.
