The Swimming Revelation

So, I will no doubt sound ridiculous and ignorant to some but I JUST figured out why I was getting so tired when I would swim laps! You see, I'm training for a mini-triathlon and it's in two weeks. I've been working hard, but I just never could seem to free style swim the full distance (12 legnths) all at one time. I kept thinking it was strange that I seemed to not be in good enough shape to make it, but I would get soooo out of breath! WEll, yesterday I was swimming along on about my 3rd lap about to drown and I had this revelation: I completely hold my breath when I'm under water! Then I quickly blow out before I come up for air. DUMB! I got kind of hopeful with this discovery. So, I started to make sure I was blowing out the whole time under water and then breathe in when I come up... Never holding my breath at all... Novel concept? Well, apparently it took me like 20 years of my life to figure it out. All of a sudden I could swim forever! I swam 24 lengths after that without stopping! So exciting for me!
