You have a beautiful family. I feel very identified with this post because I think it also I spend the time required to take care of myself and, as most of the human, blame to the lack of time but really is no excuse and I know. Make sport with your wife I think a great idea because if one day one of the two feels lazy the other will be there to motivate. Thank you for sharing your feelings and remember me that I also should I take care of myself a little bit more. Greetings!
This is the hope and I think it is going to be 50/50 as to who needs to motivate who :)
You are most welcome.
