I've been working on that for a while too. I'm about 5'10" and 180 at the moment, and I'd like to get down to 170, but I'm not sure if that's realistic because I'm not built to be skinny and really if I just improve my muscle tone and work off some fat I'll be more than happy. To that end I've been working out every couple of days for a while, but I haven't done it for about a week because I got sick and exercising when sick is no fun. Hopefully I can get back to it today.
