Have you considered bodyweight training? I much prefer it to weight lifting. I can do it in my home without a bunch of space-hogging equipment. You Are Your Own Gym by Mark Lauren is a good place to start. http://www.amazon.com/dp/0345528581

As long as everyone's throwing in their experiences:

I'm a fan of body weight exercises; no equipment needed (beyond things like a door or a table). I started with Mark Lauren's book [0], which has a set of 10 week programs and lots of exercises to choose from. I could probably plan my own program now, but it was good to have a start to learn exercises beyond the basic push ups and sit ups (although you can get along way with those), particularly (for me) lower body ones like squats and lunges.
