This document discusses four swimming techniques without forward motion: back floating, where one lies on their back with minimal leg movement to stay afloat; survival floating, similar to back floating but on one's stomach with periodic head raising to breathe; treading water, using kicks and hand movements to stay afloat with one's head above water; and sculling, a figure 8 hand movement to provide forward motion or upward lift in activities like surf lifesaving and water polo.
