So, if you have a housekeeper more than 4 times a month, Paris and I suggest you then ALSO hire a personal trainer. If you can afford a housekeeper you can afford a trainer. That way you will make up for the lack of exercise you would normally get from mopping, cleaning and putting groceries away.
General Housecleaning: 204 cal p/h
Mopping: 238 cal p/h
Carrying and putting away groceries: 170 cal p/h
Granted, if you have no complaints about your bod, screw the trainer!! (not literally) :))
