Swimming is definitely something I've thought about, especially because I want to be good to my knees as well - years of outdoor basketball took its toll haha. My problem is that I find it pretty boring, so I have a hard time getting motivated. I should just do it anyway, or make some time to go to the beach or something.

Same here. My workaround: elliptical exerciser, and a tablet with a good screen.
