For exercise, the key is finding something you actually enjoy doing. So not to just do it as a means to an end but for the fun of it itself. That will add some extra motivation besides just looking good for your spouse. I have taken up my favorite exercise from high school. I've been wanting to do it for a while but I had to travel overseas to get the equipment I needed so I have only been able to get back into it recently. It just happens that it coincides with my husband's MLC that I have been able to do it.
