Frank, how about a tandem? That way if your legs get tired she can do all the peddling? I did think of getting one of those motorized bikes but they are far too expensive. With the motorized bikes if I get tired, the motor can take over for me.

Doing housework is a workout! I make that my main exercise program. It works out great - I get a workout AND a clean house. lol I try to do this 3 times a week. When there are groups of things to put away like DDs shoes in the living room, I don't gather them all up at one time. I make several trips from the living room to their bedroom.

I don't know what it is about them and their shoes. They come in, sit on the couch, take their shoes off and there they stay. Right now I have 2 pairs on the floor. That is 2 trips to their room. (Mind you, I only go to the door way and set them inside the door. Their room is their responsibility, not mine. lol).

I have a small kitchen so sometimes when I wash the floor, I do it the old fashioned way - on my hands and knees. Then as I wash, I do yoga stretches. It works for me.
