I'll take the opposite tack as Boopdot and suggest you start with something simple that doesn't require you to go get anything. The 100 pushups program is quite good, for instance. If you want one exercise you can do at home, pushups aren't a bad way to go.
Now before all the weight-heads chime in about balanced workouts, I'll say that the big point of starting with something like this isn't that it's the only thing you need to do. Instead, the main point is to start you doing something on a regular basis (100 pushups is a 3 time a week workout) that will show you results quickly. It can help you build the habit of working out. Taking that as a starting point, it's pretty easy to add something like a regular run or bike ride, some planks, et voila! You've got a good, basic home workout!
