I'm about a year away from my wedding (having some issues with flight details so haven't nailed it down yet), but FI and I are planning to use this year for gradual changes in lifestyle with the main goal of looking better naked! That's basically what it all comes down to, right? Although looking great for a beach wedding is an awesome motivator, we really wanted to make longer term changes (like all of us i'm sure!).
I've been doing Turbo Jam for the last month or so and have been really enjoying it. I think I need to work some more on what I'm eating as well though because apparently it's 80% what you eat and 20% how much you exercise!
Anyways, I've seen a few people asking about inexpensive dvds for working out and i just thought i'd point out the torrent sites (ex. isohunt.com). lots of the videos mentioned are available there (P90X, Turbo Jam, Shred and others i'm sure).
