kickass man!
Yeah what Sean says rings true. Ilost weight like i had worms or something for the first 4 months, then it slowed down hard. What happened was I started focusing more on speed instead of "jsut making it", and I started gaining weight...despite my waist not growing any. My legs started thinning out, and the fat was being replaced my muscle. Then finally the weight loss is starting again since I havent had a speedo for a while, but I'm gettin one again...I don't care if my thighs are the size of small volkswagons...I like trying to beat my old times
You'll definately get stronger, and you'll notice how much easier it is, breathing wise too. Actually on a bike commut I finally learned proper breathing technique. I used to huff and puff like mad while doing anything...it wasnt until I was on my biek on a 3am commute that I noticed I was doing it, and slowed down for a few blocks until I could take on normal breathing...man it was so much easier after that!
