Let's settle this!

I'm asking for your help to convince me to exercise, or not.

Dh and I have had a forever-long disagreement about the benefits of working out. He says it is the cure-all--I'll be able to go off my depression medication, I won't want to sleep until 8:30 a.m. (when we go to bed at 11:30), I'll have the energy to clean the house, I'll have a better body image, etc, etc, etc,....

I say that I hate exercising, and nothing will make me happy if I have to do it. Plus, it's too hot and/or cold outside and the gym costs too much. I already get enough exercise when I go grocery shopping with three kids. I may be able to get out of bed before 8:30 if our kids will stop waking me up in the middle of the night (or if they will stop getting in bed with us). And if I exercise, any bit of cleavage I have will disappear, and how will that improve my body image? Any extra energy I get from exercise will not be wasted on cleaning the house. No, instead I may want to start doing arts and craps with the kids, or take up scrapbooking (that was for you Alicia).:) Besides, I'm 5'2", almost 34 years old, and 120 pounds. According to the body mass index calculators, I'm in the middle of NORMAL. I know I could tone up a bit so I feel more comfortable in my jeans and so my upper arms wouldn't jiggle so much. I just don't think that exercising will make that much of a difference, so why kill myself for nothing?

So I'm asking you. Please share with me stories of how you have witnessed the benefits of exercise, or, how it just wasn't worth the effort.
