I find that if I have a buddy to work out with, I'm more likely to do it. I have a couple of friends that I go to the gym with through out the week on different days and times and I always go because I feel like I'm blowing them off if I don't go. I would suggest setting a time that you and your husband can both go sit in the basement and get on those bikes...maybe during your favorite tv show. Watching tv keeps me on the bike or tredmill because sometimes I want to finish the show lol. Or maybe you can invite a friend over and the two of you could do the same.
Good luck and congrats for getting yourself started on working out!
