Typical traditional circus consists aerial acrobatic (trapeze-, rope-, or silk artists) and normal acrobatics (flexibility or floor acbrobats). Also jumps from trampoline or spring board individually or in groups and human pyramids are part of circus. Joggling with different tools (balls, bounce juggling balls, clubs, rings, devils sticks, diabolo) dagger throwing, magicians and talented balancing (by bike, hands, strings) are important and known part of circus.
In circus you do not compete against each other but instead you can enjoy practicing circus as a hobby just beacuse it is fun. And why not - while being super fun, there are not many sports that develop your skills as much as circus!
