Background Information
An acrobatic move in which someone completes a full rotation of the body by:Lunging headfirst into a handstand Springing from the floor with their hands
Leaping back to an upright position
Performed in various activities, including cheerleading, gymnastics and break-dancing
Performer does not see where their hands will land until after the move has begun Slide3
Steps to a Backhand Spring
Start in resting position Fully extend arms up straight into the
air
Anteriorly
adduct
