The majority are at least 5'7" or 5'8". There are three categories of cheerleaders: school spirit squad members, competitive athletes, and professional cheerleaders. School spirit squad members typically join for a variety of reasons, including the popularity or prestige of being a cheerleader. They may also want to participate in activities without being ranked against other students' performances. Competitive athletes usually join to try out for their high school's team. Professional cheerleaders often have contracts with sports teams or entertainment companies; they make money through appearance fees and bonuses based on how many fans they attract to games or events. For all levels of cheer, it is important to have good posture during cheers. Shoulders should be back and pulled back, not slumped forward. Feet should be together and pointed straight ahead. Arms should be above your head and unlocked, with hands facing forward. During hooping and yelling, arms should remain by your side but can be raised higher if needed. Cheerleading involves using one's body to achieve maximum visual impact while performing specific movements associated with particular chants or yells. This form of dance/martial arts is popular with young people because of its physical nature and ability to attract attention from onlookers. It also requires skill in maintaining proper posture during intense exertions. As with any sport, there is a risk of injury if you don't take precautions.
