Something that's generally helpful to remember:
You'll enjoy some forms of exercise, and not others. Just because you try something and hate it, doesn't mean that you should give up I hated running, aerobics, the ellipticals, etc. and for the longest time I decided that exercise just wasn't for me. On the other hand, I LOVE swimming. It's the only form of exercise that makes me happy. Unfortunately it's hard to swim all year round where I am. Still, if you can't find something just yet -- keep looking, there's a form of exercise out there for you.
