Back-handspring

A handspring is an acrobatic move in which a person executes a complete revolution of the body by lunging headfirst from an upright position into an inverted vertical position and then pushing off (i.e., "springing") from the floor with the hands so as to leap back to an upright position. The direction of body rotation in a handspring may be either forward or backward, and either kind may be performed from a stationary standing position or while in motion. Body movement may be terminated upon completion of a handspring, or the performer's momentum may be leveraged so as to immediately perform another handspring or other rotational move.

Handsprings are performed in various physical activities, including acro dance, cheerleading and gymnastics. In competitive activities, handsprings may be judged on a number of criteria.

Handsprings are performed in various physical activities, including acro dance, cheerleading and gymnastics.

The direction of body rotation in a handspring may be either forward or backward, resulting in a front handspring or back handspring, respectively. In a back handspring (also known as a flip-flop or flic-flac) the performer does not see where the hands will land until after the move has begun.

A standing handspring is one that begins from a stationary standing position. For example, a back handspring that begins with the performer in a stationary standing position is a standing back handspring.

Body movement may be terminated upon completion of a handspring, or the performer's momentum may be leveraged so as to immediately perform another handspring or other rotational move (e.g., a flip, such as a tuck or layout). Similarly, another rotational move (e.g., a roundoff) may precede a handspring in order to develop sufficient momentum for the handspring.

In artistic gymnastics, handsprings are commonly performed in the floor exercise, vault, and balance beam events.
