Do any of you know of a "on land" supplement breathing "drill" that will help in pulmonary function ie. holding breath , hyperventilating,etc
Just curious if there is something you can do to augment time in the water-- my cardio is not a problem but wonder sometime if I can gain additional pulmonary function while out of training mode (swim , bike, run )
They make some different things you can breathe through which are supposed to increase your lung capacity, but I've never tried any. The best thing is to just increase your cardiovascular, so your heart is able to supply more oxygen rich blood.
