Roll in the water

This exercise should be performed in a pool where the water is at least chest-deep for the child. The child uses their upper body to build momentum and jumps forward from the pool floor with their body tucked into a ball. The arms can assist in generating momentum. Once a forward roll is successful, the next step could involve attempting two consecutive forward rolls or a backward roll. Two components are particularly important for the core exercise: momentum and a tightly tucked body. Both are trained during the water somersault. This preparatory exercise also requires much less courage than the actual core exercise.
