I have an eliptical exerciser that I swear by.
I have been using one since 2004. I went through 2 cheap ones and finally bought a middle of the road one. I'd like to get a really good one but it's not in the budget presently.
I use it every single day miss the occasional day and when I am hurting too bad to use it. Zero impact on the joints.
I used to run-- I miss that, way too hard on the hinges though.
I should be swimming but I don't, we have a brand new pool here too. But I use the excuse that it's too expensive. I swim with the kids in the summer a lot.
I golf, when I can, another expensive one. I'll probably be able to get out a couple times a month this summer.
My dad is a golf pro so I grew up golfing, he taught us how to properly warm up too so I don't hurt anything. I do think I need new clubs though-- he's gonna set me up, my old ones I think are too short-- longer means not having to lean over so much.
I have a bike but need a new one, the old one is a conventional 18speed-- I need a granny bike, where the handlebars are higher than my butt.
My favorite exercise is dancing but I don't get out to do that very often at all especially since the kids...
