I got my DH to buy a road bike, and he does ride with me at least twice a week or so. His job is in DC, so he can't ride during the week at all. I try not to nag and just be happy when he does get out there with me. He's lost 25 lbs, partially from cyling with me on the weekends and hitting the excercise bike at his hotel during the week, and partially getting better with portion control (hard when he has to eat out 7 meals a week).

It's funny at races, because he's getting my bike ready and getting me water or a recovery drink, pinning my number on, taking pictures, just like all the wives and girlfriends do for the guys.

He'll never take it as seriously as I do, but that's ok.
