It isnt exercise alone, it is exercise plus basal metabolism.
Well, first of all I didnt go from couch to 3000 overnight a. This is a buildup of years. I dont think the zero to 3500 plan is the wisest. Its what they do on TBL and A LOT of them end up hurt. But it is possible. It's just time consuming.
And remember they are a lot larger than you and I are. Fitday lists sedentary metabolism for a 285 lb woman (about where the last woman started?) as 2600 calories. Getting to 3500 from there is not that tough. Weight lift for 30-40 minutes. Cardio for 60-90 and you are there.
For me 3400 is about my peak, but my sedentary metabolism is closer to 1700. And it takes me several hours to get there. But I've been marathon training for years now. When you build up to run for a long period of time, you can back off the running and add in lower impact cardio at about double the time without really bothering anything, if you have that kind of time.
A 3400-3500 calorie day for me would look like
am: 30min elliptical(moderate)/30 min weights(vig)/30 min row (high intensity)
pm: 10 mile run (moderate intensity)
later: 1 hour power yoga.
