A swimmer intends to jump into water from a height. How should he adjust his body so that he is able to form a loop in air easily?

In order to form a loop in air easily and jump from a height, the swimmer should curl his body. This way the moment of inertia would decrease and hence the angular velocity of the swimmer increases.
