Someone once said she does housework as her workout. how much muscle can you gain or weight lose?

Unknown: Unfortunately, it is not that simple. Housework is hardwork and can burn calories. While how many calories you burn depends on many factors, you can expect to burn approximately 200 calories for every hour spent in moderately intense housecleaning. To lose a pound of weight, you need to burn 3500 calories more than you take in. It is best to not try to lose more than 0.5-1 pound/week.
