The housework to minimize abdominal fat is: cleaning the floor (comparable to sit-ups)

The most healthy and flexible indoor exercise is yoga (you can buy a simple CD and practice it yourself)

The most convenient family exercise that consumes calories is skipping rope (preferably on the carpet, but not on the first floor).

The easiest way to keep fit is to walk around the house as soon as possible.

The best exercise to do in bed is: sit-ups or lifting at both ends (straighten your body and raise your head and feet at the same time)

Try it, as long as you persist, you will gain a lot!
