nope this isnt spiritual. its really rather vain and unimportant. but I must know.

I have been walking on the treadmill for a week or so, I did four days, skipped four days, got back on it today. I dont get much done with mike is home. as an aside, this is because he is gone so often that when he is home I find my body propelled to whatever room he is in. I sort of hover. its a little embarrassing actually. I have a mental block against doing my own thing when my husband is home. I get over it after he's been home a few days or a week or something...but I still have a hard time exercising when he's home. couldnt really say why. ANYWAYS. my question!

when I'm on the treadmill I wear sweats. its in my garage and I want to sweat. I go for about forty five minutes, while speedwalking. I pump my arms in different directions to songs I like, just for the extra bit of work for my heart. I go two or three miles depending on if I do an hour or forty five minutes, and it tells me I burn 3 or 4 hundred calories.

HOW LONG DO I HAVE TO DO THIS BEFORE I SEE SOME WEIGHT COME OFF???

I'm dying of a lack of motivation. I need a light at the end of the tunnel...it would make it infinitely easier. any one got an idea??
