I'm pretty with lucky with equipment really, virtually everything I need. Weights wise I have a set of adjustable dumbells that go up to 21 kg's each, and a nice bench that has 3 incline settings.

I've also got a bike, a rowing machine, and now Kinect has come out, a decent fitness program on that.

I used to go to a gym but I never went often enough to make it worthwhile so now my lounge is basically a gym.
