One word, goingape: "Two-a-Days"....
I read a story a couple years ago about some guy who wanted to join the Army. He spent his AMs pre-breakfast, his lunch break, and after dinner walking a several mile loop. He lost like 50 lbs and passed the physical.
Ok, so he was doing 3-a-days, but I assume that "if you have a wife, then you have a life," so you will have to focus a bit more and share a bit more.
Good luck with that.
