Constant weight apnea

Constant weight (CWT) is a freediving discipline recognised by AIDA, the International Association for the Development of Apnea, in which the freediver descends and ascends using their monofin and/or with the use of their arms without pulling on the rope or changing their ballast; only a single hold of the rope to stop the descent and start the ascent is allowed.^[1] Constant weight is one of the eight disciplines considered for international competition, the others being constant weight bi-fins (CWTB), constant weight without fins (CNF), static apnea (STA), dynamic apnea without fins (DNF), dynamic with fins (DYN), free immersion (FIM), and dynamic apnea bi-fins (DYNB).^[2][3][4]
