6 months ago I rescued a dog. At the time, I was 314lbs and he was 5 lbs overweight. My commitment to get him healthy I knew would be good for me. At the time I started Jenny Craig and got down to below 300, and one day, wanting him to get a little more exercise, I found myself jogging. Me, jogging. I'd only go for a house or two, then walk, then do the same, not really feeling challenged by it, but pleased that I could run that much for a fat chick.
Then yesteday it was raining, so I went on my treadmill. I found I could do on it what I never thought I could. When I first got the treadmill years ago, 2.8 seemed fast. Then at 314, I thought 3.4 was fast.
Well, here's my current routine. For just 20 minutes I run 1-2 minutes at 3.8-4.0, then walk 1-2 minutes at 2.8, then cool down last 2 minutes of 20 minutes at 2.5. FWIW, my heart rate during this is 136-168/171.
Ironically, though I'm only burning 160 calories or so according to my machine, I lost 3 lbs recently.
What amazes me more than the fact I can run at an MPH I thought I couldn't is that after I've cooled down I think to myself, hmm, I could do that again.
I'm proud fo me.
