Yes. In Allstar cheerleading, you get to tumble, (just as much as gymnasts do) stunt (which takes a lot of work with balance), lift up other girls (takes a lot of strength) and move quickly throughout the routine. It takes a lot of work to do all of those things. Your not just standing around...
Yeah, I noticed them. I was like "Woah, look at all the refs." to my sister when they showed them. I thought it was funny, and cool that they dressed up like a ref.
