Unless you live next door to a gym, I'm voting for a home gym being the best. Mine is far from complete, but it has allowed me to train intensely without having to worry about "did I bring a good change of clothes" or "did I forget something" or even "aw crap now I have to buy the Gym's version of a creatine/protein product because mine is at home." It has also allowed me to stop trying to sneak stuff in to work, because it's just not necessary. Focus is again where it needs to be at the gym, intensity, my music gets played loudly, and focus is where it belongs at work, myspace, youtube, failblog, explosm, etc.
