I just found for me personally I couldnt' work out at home. I tried it, but there are too many distractions around. Phones ringing, dog barking, people ringing the door bell, the UPS guy out front, and on, and on.
I can go to the gym, leave my pager and cell in my truck, and I have a hour away from the rest of the world...i lOVE it!
