I'm afraid of joining a gym.....too skinny?

In the City That Never Shuts Up, it’s refreshing to hear from someone who would likely not, say, march up to a pregnant woman in a restaurant and inform her that her ice water is “bad for the baby.” The difference in this case is that your concern seems well-founded (unless, supermodelishly, she lives on cheeseburgers and just doesn’t gain weight). And it isn’t as though you’d passed her once in the park; you have to deal with her daily, which makes it your business. The problem is, if she does have a disorder, a mini-intervention by a concerned stranger isn’t going to flip on her “I gotta get help!” lightbulb. And yes, you might piss her off. The best option for all involved: Air your concern in a little sit-down with the gym manager or a respected trainer; the onus is on these folks to be vigilant about their clients’ well-being. Then, knowing you’ve been a good Gymaritan and done all you can, try to focus on your own ***.
