I do like 20-30 mimutes a day on an elliptical (unless someone is home. then no thank you.) depending on what time I finally get around to doing it, what I ate, the resistence, etc. and yeah it's hard, but it's supposed to be. and I can do 30 minutes of that. as a fattie. and it gives me great joy that I can do that. and that the non-fattie people in my house, that like to make me feel like crap for being a fattie, are dead and can't hit 5 minutes (even with 0 resistence.)
