Amazing Improvements!

When I first got my treadmill, a little over a week ago, I could barely jog 30 seconds on it. Today...even after taking 2 days off in a row, I was able to jog about 15 minutes out of 20! 8 of those in a row--jogging between 4-5mph. I did a 1 minute warm up, then the mph went from 3 to 4.5. I almost turned it down, but decided to go for it. When I first looked at the display, it said 18:56 *counting down my time*, when I looked again while dripping in sweat, it said 10:40ish. I remember looking and at one point, for about 2 minutes worth, I was jogging at 5mph. then I stopped for a few seconds and had some water, then I did a fast walk for about 30 seconds, then ran for a minute or two, then fast walk, you get the idea. So I *think* I jogged for around 15 minutes out of the 20. The last 2 minutes of the 20 were the cool down/walk. It amazes me that I can see such improvements in a little over a week. by the end of my work out, I was sweating my ass off, but I wasn't overly winded. My first day I was about dying. Oh yea----and today, I was on the weight loss setting! Woohoo!! Also, when I weighed myself yesterday I was down to 219.8! today I'm back up to 220.6, but....I'm losing weight. I really NEED to get a tape measure to measure myself! I know I've lost inches--even Matt said something. :)
