I have a yoga mat, a pilates ball, a couple of hand weights, and a wheel-type thingy with handles... and i actually use these things! My parents have a treadmill that they never use. My uncle has a rowing machine (an erg?) that he uses everyday... It's all very personal, but my feeling is that you don't need to spend a lot of money on fancy equipment to get results. I have a friend who swears by lifting his own body weight.... he is 3% fat. cool, eh? He has this neat little routine he does everyday, with just his own body.
