I suppose it's certainly healthier than my past addictions to smoking and pizza. But I honestly don't feel good unless I get 90 minutes at the gym each night. I do it late, so I always wake up feeling wiped out, and yet never feel like I've quite worked out enough.
Part of the interesting element of my addiction is that it has a side effect (beyond losing weight) of watching a ton of TV. I purchased a DVD player and utilized my Netflix queue to get through multiple TV series while on the elliptical trainer. Right now, I'm wrapping up the BBC miniseries State of Play and have recently torn through Generation Kill, Torchwood, Firefly, Damages, Deadwood, Mad Men and a series of movies. I've also re-watched a couple of the seasons of The Wire that I own. So I imagine I'll use this journal to provide my thoughts on them as I wrap them up.
Another side effect has been the unfulfilling purchase of fitness gadgetry. It never seems to work out: be it dumbbells I rarely use at home (though I thank Amazon Prime for ridiculously letting me ship those for free), that chin-up bar that doesn't work on any of my door frames (but I still use as a push-up bar occasionally), the FitBit that I'm still waiting for word on when it will ship (and will review once I get it) and the Vibram Five Fingers that I actually love, but ordered just before it got cold and wet.
