I don't really like cycling, but I've found I dislike driving more, so replacing car trips w/ bike trips has worked really well. I get exercise, save money, I get better parking spots, and I'm not stuck in a stupid car. Oh, and I'm quite competitive, so I like to see how quickly I can get from A to B, so my heartrate stays high.

I also have gymnastic rings in my garage for my upper body. I'm not a fan of that either, but it at least feels cooler than lifting weights. So I'll alternate between doing errands on my bike and using the gymnastic rings.
