Marita - I have a Schwinn recumbent bike that has various programs on it (ride in the park, interval training, hills course, etc., or I can just ride it at my own speed). I used it quite a bit while I was losing weight after my weight loss surgery, then I didn't use it much prior to surgery when my knee was really hurting. However, I can use it now and have been riding it quite a bit lately to keep my knees limber. They have me ride a bike at PT before I do my exercises. I like having one at home because you can watch TV or read while you're exercising. I would definitely recommend getting the recumbent type because of having a back rest. I'd also suggest looking for one with arm rests, which the bike at my gym has but mine does not. It makes it easier to ride for a longer period of time!
Mony - I also agree with sticking with the younger kids!!! I'm sure it would be mortifying for your sons to have you sub in their classes, LOL!
Nabbie - I'm sure your family appreciated your being there for them! And it was nice for you to be able to get flowers to your mom before Sunday! Mari asked my hubby about a Mothers Day gift for me and I told him to let her know that I just wanted a one-on-one phone call, so we chatted for over an hour tonight by ourselves about wedding planning stuff. I loved it!!! Of course, I filled my hubby in on the important stuff afterward.
