Well, it'll help your overall health to do it. I personally just got back from a cardio kickboxing class at the gym (literally just came through the door!). I haven't always been a gung-ho exercise person, but I'm slowly becoming one in large part due to these classes! I wear a Heart Rate Monitor, and depending on how hard I work, I can burn 500-650 calories PER HOUR in a cardio kick class. And I have fun while I'm doing it!
Since losing weight the first time, I've realized that incorporating exercise is something I need to do in order to keep the weight off permanently. If it's a high intensity class and you burn, say, 750 calories per 1.5 hour class, then you're going to be burning 1500 calories per week. So, through exercise alone you'll take off maybe 1/3-1/2 of a pound (since one pound = 3500 calories).
But! Maybe you'll like it, and maybe it'll lead to a more active lifestyle for you in general. It's scary, but I've started BECOMING one of those "let's get up in the morning and go to the gym" people--when I was SO sedentary just a few months ago.
