One of the most used shapes, but often difficult to master, is the hollow body. Here, the gymnast contracts the core and rounds the shoulders and glute muscles by squeezing to create a gentle curve. The head should stay between the arms. This position strengthens the midsection and is vital for control during swings and holds.
Appropriate uses: Tap swings or giant swings on bars, the snap down of a roundoff or back handspring, pre and post flight of a front handspring vault
Inappropriate uses: Arched based skill such as front or back walkovers
