Exactly! You can go both ways with this: at my house, I have exercise equipment, up to and including a barbell and plates. If I feel like grinding out some sets real quick, I can. There is absolutely no comparison to working in an office.
And the mention of the kitchen in the post is spot on too - it's just way too convenient to have my full kitchen at home for a quick smoothie. Some projects at my job don't even have a refrigerator for Pete's sake!
