i think cheerleading is definitely a form of art. or at least it should be! not everyone has what is takes/and or the determination to become a cheerleader. it takes practice and hard work, along with being able to master a move correctly, like dancing. dancing is a form of art, and i think cheerleading is too. not everyone can dance, just like not everyone can be a cheerleader.
