I know what you mean about finally finding a fitness community (like the alliteration? I should have continued with "fitness friends") you can relate to . None of my friends and acquaintances are particularly interested in fitness. The closest anyone comes is a good friend who has had a weight problem for a while, and finally lost weight by following the "curves" diet that another friend of hers had turned her on to. She now uses a Bowflex that her father bought for her for her birthday, but she's definitely not into it as much as I am into my workouts.
Another coworker is concerned about staying in shape (sort of) and I have passed some videos on to her, as well as a stability ball. I think she probably hasn't used them yet.
As for people who don't want to do what it takes to get and stay in shape, our former secretary was one of those whiners who continuously complained about the weight she couldn't lose (as well as her aches and pains and high blood pressure and high glucose, etc., etc.). I try not to be too pushy with diet and exercise advice, but when she would express interest, I'd suggest she get on a walking program and also suggested some changes to her diet (ie: eating more veggies and whole foods, and cutting down/out the cheesburgers, piles of restaurant mashed potatoes, etc. --though I did approach her more tactfully than that, making small suggestions here and there). Well, that was too much for her, even though she said she'd "do anything" to lose weight. Evidently, the only "anuthing" she was interested in was some kind of pill (she got some shaklee diet program) or shake (She'd have a slim fast shake for lunch a couple of days in a row, then have a cheeseburger and fries for lunch the following day). She was even considering taking phen-fen (sp?) right before it was taken off the market.
