There's many different types of cheerleading, here I will explain those types. Note: I am a cheerleader.
1) Sideline Cheerleading- a team of cheerleaders (often all female but can be coed) who cheer on a sports team. The sports team they often cheer for is basketball or football. This is where people refer to cheerleading as not a sport, but that doesn't mean its easy. Sideline cheerleading is not what you think, this is what you might be thinking it is "Oh yeah boys lets go team whoooooooo" NO. Sideline cheerleading involves jumps, stunts, and tumbling! Yes, gymnastics!
2) Competitive Cheerleading- a sport is a team that competes against others, therefore this makes COMPETITIVE cheerleading a SPORT. The competitions are very extreme and dangerous. Before you say that cheerleading is easy, try to go see a cheer gym's competition. Now I'm not talking about your local reciational gym. Anyways, schools at the middle, high & college level most often have competitive teams. They are very serious!
3) Allstar cheerleading- the best of the best. Go watch Califorina Allstars Smoed or Sting Ray Allstars orange, or Cheer Xtreme Senior Elite. Alllstar cheerleading
