I do cardio kickboxing, run (occasionally), go for long walks and bike rides outside and also weight train.

My big one is my stationary exercise bike and I try to incorporate some strength exercises like various types of push-ups (regular, wall, incline, etc.). Sometimes I throw in my DWTS workout DVD or a yoga or pilates DVD.

I'm not a huge treadmill person either! I do it because of couch to 5k and if I didn't have music to go with it, it wouldn't happen!
Zumba is cool, kick boxing, Shun T's Hip Hop Abs (Hip hop version of zumba).

I bought a recumbant bike (the one's with a back) online for like $125. I love it because I can read or watch tv while I exercise. Plus it is low impact and it doesn't hurt your back like a regular stationary bike.

I do a circuit training class at the gym twice a week (strength training interspersed with some cardio to keep the heart rate up).

On the off days, I try to get some other type of cardio in at the gym - I was doing 30 mins on the elliptical each time but someone recommended switching to the treadmill. I don't like running, so I do a fast-paced walk at a steep incline. I find it works me a lot harder than the elliptical!

August to October I train for the CN tower stair climb too. I start with 10 flights 3x per week and gradually build to 85 flights 3x per week. Like running, it is amazing how quickly your body adapts and is able to go faster longer.

I personally cant stand the gym. no clue why as i used to go all the time when i was younger (mid teens). Nowdays my exercise is my job (i trim horses hooves), fixing stuff at home (oh the joys of fencing!) and riding and general training with my horses as well as looking after the animals/etc. I know it's not the same as go to the gym type exercise but it keeps me sane haha!

I normally lift. I want to swim again. Now that's a great endurance builder.
