Constant weight (CWT) is a freediving discipline recognised by the AIDA International (International Association for Development of Apnea) in which the freediver descends and ascends using their fins/monofin and/or with the use of their arms without pulling on the rope or changing his ballast; only a single hold of the rope to stop the descent and start the ascent is allowed. Constant weight is the common sportive depth discipline of freediving, because of the specific fins or monofins used in it. Constant weight is one of the three disciplines considered for international competition, with static apnea and dynamic with fins.
