BDG - imagine the training you would get dragging his dead weight! Your bike would feel like a feather afterwards! Trust me, I know!
My wife is super supportive of my addiction. She is an enabler. Why, just last fall she sent me to a bike shop while we were in the USA and said - "Don't come out until you get everything on your list and maybe a little more!" (she knows I hate to shop) - two hours and about 700 dollars later I escaped.
Back when I was 40, I weighed 270 lbs with no energy, now I am under 190 and have too much! She is in shape as well.
She only complains because I am not taking enough time off - I get grouchy. Why, just a few days ago she said, "Take a Hike!" (just kidding

)
