A somersault (also flip, heli, and in gymnastics salto) is an acrobatic exercise in which a person's body rotates 360° around a horizontal axis with the feet passing over the head.
[1] A somersault can be performed backwards, fowards or sideways and can be executed in the air or on the ground.
[2] Somersaults may be performed with different positions, including tucked, piked (bent at the hips), straddled, and layout (straight body).
They can be trained by beginning with an Arabian dive roll and adding a front salto to it.
[9] In 2019, American gymnast Simone Biles was the first woman to compete a back triple double: two saltos backwards with three twists in a tucked position.
