Proper Posture

Even the way you sit in your chair can help you lose weight. Keep your back straight against the chair and your feet flat on the floor for best results.

Sweeping and Vacuuming

Sweeping the floor and vacuuming the room are good exercises. Sweeping builds arm strength as 
you work and mopping works the abdomen and muscles in the back. Therefore, sweeping trains the arm and makes arm muscles stronger. Vacuuming works the lower portion of your body like you back and legs.

Mopping and Scrubbing Floors

Mopping and scrubbing the floor consumes a lot of calories, which makes them ideal activities for losing weight. All the bending and back and forth motions work every part of the body, which is what a good exercise should do, without concentrating on just one area.

Brushing Toilet

Yes, even brushing your toilet is a form of exercise that can help you lose weight. The bending involved works the back and legs while the scrubbing and brushing motions works the arms. Clean your entire house AND lose weight at the same time! What an awesome idea.
