CLEANING your house thats physical just do it with more vigor!!! I personally love exercising, always have and always will. The only thing is I never think of walking, dancing, gardening as exercise, its just something I like to do. I do weight training as well but I think of that as exercise, but I get the best results from weight training, so I just do it and the more muscle you have the faster your metabolism.
What i'm trying to say is find something that you find fun or things that just have to get done like cleaning and mowing and you might enjoy them more and put more effort in cause you know its great exercise.
