Floats and back floats are commonly used props by swimmers of all stages to assist their own swimming. The floating board is mainly used to practice decomposition movements, and individual arm strokes and kicks can be practiced; the back float is mainly used to coordinate the movements of various swimming styles to avoid being unable to complete coherent movements due to the body sinking. If this is your first time in the water, it is recommended to choose a floating board + back float combination, which can give you more security and courage, and greatly reduce the fear of water.
