text: what shape do you have to be in if you want to start being a cheerleader for your school?   fit and slightly muscular. it'll take quite a bit of energy to run up and down the fields shouting yourself hoarse. also, if it's stunting, you'd need to be even more fit/muscular because you'd have to support the cheerleaders at the top. to be the cheerleader at the top, you'd have to be small in physique, thin and less than 100 pounds so that the other girls can support you.  i hope this helped.=)
