Hello all, I am new to this forum, as well as to competitive masters swimming (nutshell: swim club member in my youth, returned to it as an adult solely for exercise, but something about turning 40 made me want to get more serious:) Reading posts on this forum, I have seen people talking about implementing things like t-shirt swimming, parachute (??), as well as dryland training wearing a snorkel (seriously?;). Can anyone say anymore about the tricks they use to improve lung capacity. I need 0-1 breath on the 25m, but a whopping 5-7 when I do a 50m. Thanks! Jennifer
