My particular program defines exercise as "moving your body through space," and does not have any specific requirements as to how you arrive at your 2000-calorie expenditure. You can walk dogs, mow the lawn, walk through the mall, go rollerskating, play a sport... or you can, as I do, go to the gym, and bring magazines and cds to help the time pass as quickly as possible.
At my weight and age, moderate aerobic activity burns about 15-16 calories per minute. At that rate, burning 2000 calories per week means spending about 30 minutes four times a week, 45 minutes three times a week, or 1 hour twice a week. It's not that difficult to contemplate.
Obviously, as Ig points out, if you're only walking, it's going to take a longer period of time to arrive at that kind of calorie-expenditure goal. I choose to use an elliptical trainer because that gives me a decent calorie-burning bang in a relatively short investment of time.
Though it doesn't give you that kind of calorie bang, weight training does burn some calories, and moreover, it increases the amount of metabolically active tissue in your body, so it's important. I try to work in a few sets at the end of each aerobic session.

It's just math.
