One of my hobbies is aerial silks. Aerial silks are one of the types of circus art. I've only been doing them for six months. But even in half a year you can learn to do quite complex things. These competitions are called festivals. At the festival, you need to perform to music 3 minutes and 30 seconds long. Also, each participant must have an image. There are different types of exercises for numbers the very first thing they teach is locks and climbs. Without them, it is not possible to make other elements. After the ninth grade, every gymnast can enroll in a circus school and then go to work in a circus. I think that aerial silks is a very interesting and exiting hobby. Thanks for your attention :)
