In our final installment of the Butterfly Breathing series we talk about the shortest race in swimming the 50 yards or meters. Ideally a swimmer won't need a breath in this short race but it depends on your age and ability but knowing when you are ready to go no breath is key to performing at your best. Find out if no breathing is the best swim technique in butterfly breathing for you! Remember to always train under the supervision of a coach or lifeguard when hypoxic training.
