Home gyms are great. I have had gym memberships (4!) and none have been close enough to my house to be useful. I always felt like after driving 15 minutes, I could be halfway done with my workout instead of arriving at the gym. I have a treadmill, weights, pull up bar, fitness ball, and the P90X exercise DVDs. These are pretty good DVDs because you have a whole set of DVDs targeting different things: upper body, lower body, cardio, but they are not for wimps.
Also discovered a new find on digital cable: free on-demand Exercise TV! I haven't tried any of these yet, but I plan on it.
