I've read a lot of magazine articles recently that say you can get a decent calorie burn from chores around the house. I decided to test that theory out today.  I cleaned my kitchen for about four hours.  I put some tunes on and got ready.  I emptied all the cabinets and fridge.  I vacuumed out all the cabinets, scrubbed them down and cleaned all the items before putting them back. I followed the same process with the refrigerator. I also threw some old stuff out. I kept the garbage bag on the floor on purpose so that I had to use those core muscles each time I threw an item out. 

Later in the day I went for a walk into town. I was definitely tired and my muscles were even a little sore.  I would say it worked.   I don't think it can replace navy seals or anything to that extent but it is a great feeling to know I got a lot accomplished in my apartment and burned some calories at the same time.
