In reply to quadmyre:
I never noticed the similarities between rock climbing and cheerleading until I decided to Google "ground up" and came across this paragraph:
"These are just a few of the vast number of stunts performed by cheerleaders daily. One may wonder how cheerleaders can do them in the first place. Basically, most squads use the "sponge" technique. "Sponging up", as it is called, is going straight from the ground up using a bouncing and swinging technique to gain momentum. Once the climber gets up in the air, bystanders may often hear the spotter saying something about "sticking it." This just means that the climber has not quite gained her balance and the spotter is telling her to hold it, which is usually accomplished by tightening up muscles throughout the body."

Perhaps we can start to turn to cheerleading to help advance our own sport as we reach a technical bottle-neck. How about introducing tucks, stags, pikes and layouts to our longer whippers? Pom Poms optional.
