Another married voice here. I am much more athletic than DH. He joins me when he can: skiing, hiking... But we've tried cycling together and - no way. He just doesn't have it and doesn't particularly like it. So, wonderful man that he is, he watches our daughters on weekends while I ride from 2-4 hours each day. Of course there are things I do in return. I make sure he gets a few hours at the gym (his thing) or to do something else important to him. It works out great because we are both happy about how our days went, and we share in the afternoon or evening.

All that being said, psychologists agree that couples who share interests which lead them to spend time together tend to be the successful couples. Pretty much what veronica said. As with everything else, one must strike a balance. Don't give up on men yet. There are some good ones out there.
