I have a little money saved, and want to use it to buy a home gym. We already have a treadmill that I've been using regularly. Any suggestions?

Look at how much space you have and what you like to work out. I really enjoy aerobics (so I have a step and some videos) and The Firm (which is aerobics and weights) so I have their special step and some hand weights. When we got a little bit more money my DH loves free weights so we got a bench (that can be flat or incline) and more free weights. Also, think about what you will keep up with and what you enjoy.
