Roundoff
A roundoff is a move in gymnastics similar to a cartwheel, except the gymnast lands with two feet placed together on the ground instead of one foot at a time, facing the direction of arrival. It was also sometimes called an arabian handspring.
The roundoff is a gymnastic technique that turns horizontal speed into vertical speed and can be used to turn forward impulse from a run into backwards impulse. Roundoffs are used by most acrobatic sports, including gymnastics, dancing, and cheerleading.
