Cleaning house qualifies as a full physical, mental, and emotional workout.
Physical: Reaching, stretching, lifting, walking back and forth, climbing up on the footstool and then back down, wiping, squatting, pushing, pulling....
Mental: Problem solving (how am I gonna fit all this STUFF in my little apartment!), memory skills (where the heck did THAT come from???)
Emotional: staying focused while Little Sprout is squawking, maintaining your cool as you get more and more angry and hurt that people would make such a mess, dealing with self anger because you are a natural born slob and can't seem to pick up after yourself, etc.
See? So when I am done I get a vacation.
