Start with 3 people (1 base, 1 flier, and 1 post/spotter). This is a quick, neat-looking, 3 person stunt. It goes up fast, and is great to use in crowd cheers. If your base is strong, this is an extremly easy stunt. Remember to always be careful, and remember stunting guidelines!
The flyer grabs the post's hands in front. The base grabs the flyer's foot with one hand, and uses the other hand to grab the flyer's shin. The flyer sponges by bouncing a few inches off the ground, then uses her own strength to push off and put some weight on the post instead of the base. The base pushes the flyer's foot upwards in one smooth motion, while still supporting the shin of the flyer. (this is all while the flyer is pushing on the post). The base has one arm in place, holding the flyer's first foot. The flyer puts her weight on the first foot, and dangles the second foot. She still is supporting her weight on the post. The base grabs the flyer's other foot, and both of her arms are in place now. The flyer is balance on the base's hands. The flyer and base can let go of hands now. Your post is up and the flyer can cheer along now.
For the dismount, the base dips and pops the flyer (the base must let the flyer know she's letting her down), then catches high and absorbs the catch to the ground. The flyer has her arms in a Hi-V, she stays tight, and awaits the pop from the base. After the pop have her bring her arms to her sides and catch the base's wrists for the finish.
