A somersault is an acrobatic exercise in which a person's body revolves 360° with feet passing over the head. A somersault can be performed either forwards, backwards, or sideways and can be executed in the air or on the ground. When performed on the ground it is normally called a roll.

Types of somersault
There are many variations of front and back somersaults. Somersaults can be performed in multiples, or multiples of quarter body revolutions, in some cases with additional twist rotations or ending in body landings, producing variations such as:
- Crash dive (3/4 front somersault to back landing)
- Lazy back (3/4 back somersault to front landing)
- Ballout (11?4 front somersault to feet from back landing)
- Cody (11?4 back somersault to feet from front landing)

- Randolph (or Randi) (front somersault with 21?2 twists)
- Adolf (or Adi) (front somersault with 31?2 twists)
- Full back or frontfull (back somersault or front somersault with 1 twist) less common with single fronts
- Double (double front or back somersault)
- Double full (back somersault with 2 twists)
- Half out (double front somersault with 1/2 twist in the second somersault)
