All the coolest tools in the world can't make you lose weight.
So I have my fancy dancy pedometer, right? But guess what? If I don't actually do the work of walking all those steps, it does a fat lot of nothin' for me.
Yesterday I walked 1500 steps. Yes, I know how bad that is. But you know? I just couldn't get the walking time in. Scratch that, I could have, but it would have meant I was out walking at ten o'clock at night (I don't like being out late at night, and that's late for me,) or that I was walking around my house. Both of these things I could have done. But I didn't. Why? 'Cuz I didn't want to.
And that's the crux isn't it?
That's why some exercise routines work and some don't. Some diets work and some don't.
It all depends on whether or not you try. Or do. Or whatever the opposite of not caring is. You can have all the neato equipment in the world. A membership to the best gym in town. A really cool collection of awesome workout clothes. And yup ... it's worth about zero because you just don't care enough to get your money/effort's worth out of it.
Or, you pig out on donuts when you get home from working out, right Kristi? ;)
