It seems to me that you obviously have SOME reason to want to exercise, and you seem more enthusiastic about it than just, "I should do it." In my opinion, no exercise program will ever work in the long term if you don't find something you enjoy. There are many forms of exercise I like a great deal. I love cycling, I love kayaking, I love doing yoga, I love hiking, and believe it or not I actually really enjoy spending half an hour - or sometimes more - on an elliptical machine listening to tunes or a good audiobook. Because I enjoy those activities, I'm more likely to stick to an exercise program when I try.

I would discuss your antipathy toward exercise activities with your personal trainer. She just might have some good suggestions for you about ways to find an activity you enjoy, rather than always thinking of it as medicine you have to swallow. If you can find one, you'll have a much better chance at sticking with it and seeing the benefits.
